I use a 1968 Pinarello road bike. So, I was on a nice ride when I heard this "boing" noise; before I knew it, the derailleur (I think it was the original) had tangled in the wheel. The derailleur is now in two pieces, so I need to replace it. Are there any brands or models you could recommend? Can I put new gears on such an old bike? Could this have been prevented? Anthony Green Bay, Wisconsin

I thinking of upgrading my steel fre road bike to a carbon fork. I have tried a carbon fork in the past, and found it to be somewhat unsteady at high-speed (40 plus mph) descents. I weigh 185 pounds-does weight have a lot to do with the choice of a fork? Any suggestions? Should I just save the money and stay with my tried-and-true steel fork? Steve Weinberger Spokane, Washington

I've been doing some research on altimeter watches and have come across a lot of bad reviews for watches that I thought were good. Which watch would you recommend between the Casio Triple Sensor Pathfinder, the Timex Helix Works, and the Suunto Vector (some guy told me the workmanship on this was terrible and it fell apart)? Nadav Jerusalem, Israel

Are there any one-person tents that you can combine to make into a two-person tent? Denise Centennial, Colorado

In search of the Golden Boot over the years, I've owned disappointing Danners, Limmer mid-weights that ate up my right heel, and a forgettable pair of Meridians. I have a fairly low-volume foot, and while my current boots—a pair of Vasque Sundowners (Gore-Tex old style)—work pretty well, my feet still get hot spots and ache after a 12-mile walk. What's the boot for me? Stephen Decatur, Alabama

I'd like to invest in a pair of waterproof-breathable pants for one- or two-week treks where I might encounter rain and snow. Ideally, the pants would not be too bulky as they might spend quite some time in my backpack (I hope). If possible, please note any brands that I can find in Europe! Nicolas Heverlee, Belgium

My Boy Scout troop is planning to buy some rappelling gear, but we need some advice first. Eric Shelbyville, Indiana

I'm looking for info on bike trailers, having checked out some B.O.B. models, the Yakima Big Tow, and Burley's Nomad. Any insights as to which one would be best for city commuting? Also, any suggestions for where I might look for a used one? Linda Olympia, Washington

I currently have an older version of the Tubbs Sierra snowshoes, but I find them to be too bulky and heavy for those trips where crampons are also required. How does the MSR Denali snowshoe compare to its competitors, and what is the "floatability" factor of the MSR snowshoes? It seems they're very narrow, so I'm curious if they will keep you from sinking in soft, deep snow. Scott Newmarket, New Hampshire

Will a pair of electric socks, worn inside waders, work when I'm steelhead fishing? More importantly, will these be safe if I'm wading in water? Ed Pawling, New York

I've got a Bibler Betid tarp, and looking for some extra protection for my Mountain Hardwear sleeping bag (down with Conduit SL shell). I don't want to carry the Betid's floor since it is a bit heavy, and doesn't offer the protection I want. Please suggest a sleeping bag cover or bivy that will allow my bag to breathe, yet shed any moisture from condensation or the occasional exposure to rain. I'd prefer not to break the bank on this, as well. Dennis Staley Englewood, Colorado

What are the alternatives to Gore-Tex? Are there any that stand out from a protection as well as breathability perspective? I would love a Gore-Tex shell, but cannot afford to drop $400 on one. Alex Charlotte, North Carolina

Do you know of any evidence that pepper spray is an effective defense against a mountain lion attack? Mike Rapid City, South Dakota

I have an aging Columbia anorak shell that I'd like to replace. The problem is that I'm having trouble finding any new anorak-style jackets. I don't mind pulling the thing over my head and love the big front pocket. Any suggestions for a replacement, something I can use when hiking, climbing, and skiing? Chris Albuquerque, New Mexico

Where can I buy a hip belt to use as a harness for pulling my homemade gear sled? Bruce Easton, Pennsylvania

Dear gear swi, I'm looking to get back into mountain biking but have absolutely no clue about mountain bikes these days. I haven't ridden one nor done any research in about six years. If you could reach into the vast knowledge that you call a brain and offer some advice on bikes in range of about $1000, I would be in great debt to you. (And I would prefer a hardtail.) J.R. Venice, California

I have a few trips planned in bug-infested territory. The problem is that I hate DEET. I just don't like using the stuff. And citronella-based products are useless. Is there anything new out there that is effective, safe to use, and won't melt plastic? Jake Santos Chicago, Illinois

In November I'll be doing the Hong Kong Trailwalker (www.trailwalker.org.hk), a 100-kilometer race with a lot of big ups and downs. I will probably do in about 25 hours. Last time I did it in Reebok DMX10's. I liked that they were lightweight and I think the cushioning helped my knees a lot on the downhills, but I developed large blisters and lost three toenails, which was rather unpleasant (I didn't get feeling back in one toe for six months.) I'm thinking that maybe the DMX's were just too flimsy for the trail and let my feet move inside them too much. What are your suggestions for other shoes to consider this time around? Mike Luechtefeld Dallas, Texas

After spending all my life camping in the mountains of the eastern United States, I've fallen in love with the southwest Texas desert, and I'm in the process of learning about those techniques and equipment that will work in that very different environment. No trees, blazing sun, the ground too hard to set stakes, fairly constant strong winds... The first problem to solve would be creating some shade... My Integral Designs Siltarp, which works great in the forests of Virginia, is useless as a sunshade, being almost transparent. Are there any tarps out there that would be suitable for sunshade duty, or is a piece of black six-mil poly my best bet? Bill Stell Charlottesville, VA

I looking to buy a new tent for canoe tripping in the barrens of Canada's Northwest Territories. I expect lots of wind and rain so an expedition tent would be best. But what is an "expedition tent" anyway? Robert Guelph, Ontario

In answering the question, "What's the lightest three-person tent available?" a few weeks ago, you missed by far the lightest candidate: the Stephenson WarmLite! It can weigh as little as 3.25 pounds and has 52 square feet of space! Dave SteinerNew York

What type of bag would you recommend for climbing Denali? Down or Polarguard insulation? What specific bag would you recommend? What about as far as clothing—layers, brands, models etc.? Would you recommend a full down suit? Or a down jacket and either down pants or a shell with layers? Bob Grish Boise, Idaho

I planning a weeklong sea kayaking trip in northern Quebec. I (and my backside) would appreciate any of your thoughts on a decent portable sleeping pad. Is inflatable the way to go? And what about length? We anxiously await your deliberation. Nicholas B. Westmount, Quebec

I starting to gear-up in preparation for climbs of Mount Baker and Mount Rainier this summer. I have an older Princeton Tec headlp that I use for backpacking, but can you recommend a good replacement? Are any of the newer LED headlps good enough to use when climbing? Kleet Renton, Washington

What's your take on the soft-shell craze if the activities are both ascent and descent in nature? In other words, I very interested in the breathability for aerobic activities, but concerned about warmth for activities like downhill skiing. Question is, can I have my cake and eat it too? Second, if I can have it both ways, what is your first choice and why? Brad Peacock Medina, Ohio

I looking for a cold weather running jacket that is extremely breathable and wind-resistant (waterproofness is not a necessity). I've been using Lowe Alpine's Adrenaline jacket, which is great for hiking but stes up quickly when I running hard. I usually buy The North Face and Patagonia products but I not sure that they make the best stuff for running. What do you think? Nick Kogevinas Washington, D.C.

I'm looking for a hydration pack that I can use for cycling. But, I also want to be able to stick the bladder in my Gregory backpack for extended hiking trips, thereby knocking out two birds with one bladder. I have looked at products from CelBak and Gregory, but what do you recommend? Ronald Cookeville, Tennessee

I'm discovering that my late-fortyish feet are inexorably growing longer and wider, and the hiking boots that served me well two years ago are now giving me blisters and scrunched toenails. Companions on a recent Sierra backcountry hike were wearing low-cut trail shoes that looked only slightly more rugged than running shoes, and which allowed their wearers to pretty much dance over the rocks and scree without twisting ankles. For hiking relatively rugged trails without a backpack, what sort of characteristics should one look for in such shoes? And, while I'm here, can one backpack in 'em? Richard Truckee, California

When out hiking, I'm tired of getting my good-quality boots soaking wet when crossing knee-high stres. Worse still, repeatedly taking off my boots and putting on sneakers or water shoes is a drag, not to mention time consuming. So what's the solution, gear sage? Are there any "water boots" that are sturdy enough to handle trail hiking with a 25 to 35 pound pack, but that can also withstand multiple stre crossings and total immersion? Surely I'm not the only soggy hiker out there. Mitchell Fountain Valley, California

I'm getting back into backpacking after a 20 year hiatus and boggled by the array of different stuff they're making socks out of these days. Merino wool, acrylic, Coolmax, ultimax, wickdry??? What's the deal on fabrics for HOT weather hiking/backpacking for short-to-medium trips (one- to two-day) over varied terrain and carrying moderate loads? What's good, what's bad? Lew Atlanta, Georgia

I travel consistently for my job and like to hike and cp when I home. Could you recommend a digital camera that holds up to the abuse of travel and camping but still takes great pictures? I'm looking for something around the $500-mark. I have looked at some Nikon products, but what else would you recommend? Matt Minneapolis, Minnesota

Do I need to replace my 1994 Oakley sunglasses? I wondering if the 100 percent UV protection in the lenses breaks down over the years with repeated exposure to the sun. If so, are glass and plastic lenses equally vulnerable? Joel Las Cruces, New Mexico

I live near North Carolina's Outer Banks and want to purchase a kayak for island hopping. What boat would you recommend for a beginner paddler? Jie Beaufort, North Carolina

I'm going overseas for approximately two years. Unfortunately, there'll be no camping opportunities the whole time. Before finding out I was off, I purchased a new tent, sleeping bag, and backpack. What's the best way to store this gear so it's as good as new when I get back? Gil Beaumont, Texas

What do you know about the "Stealth Can" and its effectiveness? From what I read, it's impenetrable to bears and seals in odors to throw animals off the scent. I like the idea of pre-empting animals from entering cp, rather than "teasing" them with food they can smell but not reach. Mark Ewing, New Jersey

Will boiling or adding chlorine dioxide to water neutralize all organic chemicals (i.e., industrial waste)? Also, should you filter water after using iodine or chlorine dioxide to purify it? Does ViralStop (from SweetWater) kill anything other than viruses? Basically, what's the simplest, lightest way of neutralizing EVERYTHING? Seyil Toronto, Ontario

My sweetie and I are going to Everest's Khumbu Icefall this December, where it's likely to be numbingly cold. I'd like to buy her a toasty parka for this trip and have homed in on Feathered Friends' Icefall and MEC's Frobisher. But will those jackets be significantly warmer than our current 550-fill REI parkas? Should I pay for the 800-fill down or Nextec Epic (apparently the best thing since somebody figured out how to shear a sheep) if I go with Feathered Friends? Or should I be looking at other parkas? Robert Fairview, Oregon

I've noticed a strange paradox in my personality. When I go out to the woods, sitting in some remote beautiful locale I often in want of one thing: a margarita. I've often theorized different devices that I could construct to make a blender but nothing ever made sense. And then I found the GSI hand-cranking Vortex Blender. While I would never take this backpacking (OK, maybe on a day trip to be fancy in front of my exhausted friends) I would definitely be interested in it for kayak camping and car camping—so long as the ice lasts. But does the thing actually work? Or is this really a doomed fantasy of mine? I'm skeptical about the amount of effort this thing would take to crunch up ice. I'd love to pop this out and be a hero. Brian McCarthy Glendale, California

Long time reader, first time questioner: I have long been a fan of liquid-fuel stoves, but recently read your advice about the difficulty in obtaining white gas products abroad ["Do they sell white gas for stoves in Europe?"]. I about to head out on a nine-month round-the-world trip, so would like to take along a reliable canister stove. Do you have any information on which canister stoves will mate with the multitude of international propane canisters that I'm likely to find? Europe and Oceania are my probable destinations. Aaron Green Bay, Wisconsin

I'm interested in testing the triathlon "waters." Can you suggest any good bikes for a beginner triathlon biker, say, for under $1,000? Gary Quito, Ecuador

Do you have any tips for taking a dog on trail? I'm taking my dog on her first trip and want to protect my gear without constantly worrying about it. Are those packs dogs wear a good idea? Will she dage the inside of my tent? Kieran Hosey Frankfort, Kentucky

I'm looking for a pair of Gore-Tex mountaineering pants that I can use snowboarding in the Alps, climbing in rainy Scotland, or cross-country skiing in Norway—all without maxing out my credit card. Any suggestions? Jakob London, United Kingdom

I recently unpacked my tent to be hit by a powerful smell of chemicals and mold, so bad that it gives me headaches and I can't sleep in the tent. Could I just wash it with some mild soap to get rid of the stink? I believe that the ses were sprayed with some sort of leakproof sealant, so I think that's why it smells. Janie Kuala Lumpur, Malaysia

I have been contemplating hiking the Appalachian Trail. Having spoken to a number of through-hikers, I'm told that many are using homemade alcohol stoves made from soda cans. Can you give me your take on alcohol stoves? Have you had any dealings with an alcohol stove known as the Trangia? Mark New York City

How do I wash the sweaty odor from my polypropylene toque? I used Wisk liquid detergent without success. The toque is clean but it still smells badly. I need help. Alexander Do Toronto, Ontario, Canada

Just wondering if you know of any companies that do any sort of maternity outdoor wear, the actual technical garb. I realize that a pregnancy only lasts so long and we already have to add to our wardrobe as it is, but it just so happens that my few biggest months will be the hiking season. I have tried on some of my other gear and think a few pieces will work, but is there a manufacturer who makes stuff that will actually let me and the baby hike comfortably? Charlotte Winnipeg, Manitoba

I have an early-nineties GT mountain bike with a titanium fre. It's still a good-looking, lightweight bike, but its rear U-brake has no real power. Are there any compatible brakes with better grip, or are there any pads with magical powers? Andreas Reno, Nevada

I've read your praise for the Yashica T4 point-and-shoot camera and was attempting to locate a refurbished unit on the web, when, lo and behold, up pops the new Yashica T4 Zoom with a Carl Zeiss Lens (28mm to 70mm). In the wilderness, I've always managed to catch more pictures than fish, and would appreciate your thoughts on a lightweight point-and-shoot for my arduous outdoor adventures. Scott Maple Valley, Washington

Why did Sno-Seal fall out of favor? I kept a pair of heavy hiking boots alive for years with some welt dressing and this stuff. Joe Midland, Texas

I'd like to buy my dad a comfortable bike for exercise and recreation. He doesn't like to be hunched over a bike because he has a temperental back. He also needs a comfortable seat. Is there anything for $800 or less? Joe Edison, New Jersey

I have been searching online for the past few hours for piece of equipment that I believe I saw in some gear magazine (the mail order kind). I will describe it: digital watch, with a compass, stopwatch, etc., and a lighter, signal mirror, and small knife blade with various other attachments. It hung from a lanyard and cost around $100.00 or so. Can you help me find a name for this product or where I might be able to order one? Thanks for the help. Bradford Hammar Charleston, West Virginia

For the second year in a row, we have just returned from our annual spring camping trip in southern Utah, and because of blowing dust, the zippers on the tent are EXTREMELY difficult to operate. Are there any methods for treating "dust-laden" zippers in the field? Also, now that we're back, we've washed the tents, sprayed silicon on the zippers—they're better, but still not like they used to be. Any suggestions? I've been told to buy some "zipper wax" to carry camping next time, but no one here seems to carry it. Thanks! Kirk Astroth Belgrade, Montana

I have a 2001 Honda Civic coupe and will be making a cross-country trip. I looking into a cargo rack to outfit my Civic but I'm not sure how much to spend and which brand to go with (Thule, Yakima, or Saris.) The rack will probably only be used for a rooftop storage bag. If you could suggest a rack model I would greatly appreciate your help. Pete Lptey Fairfax, Virginia

I just returned from Mount Rainier with a rope I had bought specifically for this trip but with the intention of using it for rock climbing. I hate to think of the number of times I saw it go under foot. None of my ropemates put a crampon into it, but I sure don't see myself taking a lead fall with it now, especially 100 feet up. But what about glacier travel? Certainly the guides on Rainier leading newbie mountaineers don't replace their ropes after every trip. Is there anything I can do to physically check the condition of my rope and feel comfortable using it for glacier travel? I truly hate to toss a rope after one trip.

This July I climbing Mount Rainer. My climbing partners have told me that a synthetic bag is necessary because of the rain. They recommended a 25- to 40-degree bag. We are going light and fast, and plan on using open-air bivys, so I think a bag with a microfiber shell would be a good thing. Unfortunately, I not having any luck in my search for the perfect bag. I have stumbled on only a few bags that are synthetic and have microfiber shells. Integral designs makes one, but it uses Primaloft2 as its insulation material. I have been warned to stay away from short-staple fibers because the bags don't last very long. Do you have any suggestions? Mike Ads Newark, Ohio

My wife and I are going bike camping this summer. Are there any light two-person sleeping bags, or single bags that zip together? We need the bag(s)—preferably down filled—to also fold down as small as possible. The cheapest we've found is about $500 for two. Do you have any better suggestions? Harvey Davis, California

My family and I enjoy car camping in Alaska's interior. However, as I get older, I'm finding that my back gets stiffer using my old sleeping pad and that my air mattress doesn't give enough insulation. What type of pad or combination of pad and air mattress do you recommend to minimize back pains, provide insulation, and allow for a comfortable night's sleep? Shane Juneau, Alaska

Is DryLoft on a down sleeping bag worth it? I've noticed that it's not appearing as often as it used to on down winter sleeping bags. David Morlock St. Paul, Minnesota

I'm planning a mountaineering trip to Bolivia in June. I have a pair of Koflach Degre boots, which have been fine on Mount Hood and when winter climbing in New Hampshire. Will these be OK for climbing Bolivia's 19,000-foot peaks? Do I need Alveolite liners? Brian Augusta, Maine

I would like to buy shaped skis. I currently ski on straight 160s and 5-foot, 2-inches tall. I've gotten so many different opinions on how long my shaped skis should be. Help! Jacklyn Meriden, Connecticut

I need something to go over snow terrain in the most efficient way possible for a winter approach/ascent of Split Mountain in the Sierras. Instead of clunky snowshoes, what do you think about the Yupi Skishoes? Or the Salomon Meta Skis? Between the two for rough, snowy terrain, which would you recommend? By the way, I'm a VERY novice skier, so something easy to learn is important. Jake Kim Irvine, California

In one of your long-ago columns, you gave the scoop on the well-known Cascade Designs Chair Kit and the Therm-a-Rest Chair Lounger. But in the spirit of "discovering" unknown, neglected products, does the Gear Guy have a take on the Sling-light chair (naturally, at slinglight.com)? Does this alternative, lightweight product deserve our consideration? Marshall Atlanta, Georgia

I have been searching for a backpack for extended trips, and it seems like all the local shops vacillate between Osprey and Dana Design packs. If you were going to buy a pack today, would you buy an Osprey Crescent or Dana Design Glacier? If so, why? Matt Albuquerque, New Mexico

I recently bought a secondhand Osprey backpack. Every time I use it and break a sweat, I'm overwhelmed with odorous memories of someone I've never met. Is there a way to rid the suspension of the previous owner's "scent"? Stan Gainesville, Missouri

All-knowing Gear Guru, I intrigued by Dana Gleason's concept of separating a backpack's suspension and pack into two separate components. Is this idea worthwhile? Also, Kelty is "the first licensee" of Gleason's Mystery Ranch System, and Kelty's line is significantly cheaper. Is there any difference? Dion San Francisco, California

I'm looking to get a lightweight and compact pair of binoculars to carry with me on hikes. Do you have any general tips and some recommendations for good buys? Joe Voelcker Philadelphia, Pennsylvania

I new to whitewater kayaking and was wondering about a practical, fairly inexpensive way to get into the sport. Jimmy Cullowhee, North Carolina

Several years ago, I bought a pair of "funny-looking" Salomon Adventure 9 boots. They were virtually perfect, but are finally wearing out. Since there's no sign of a similar boot in today's U.S. Salomon line, can you think of an alternative? Ray Cleveland Heights, Ohio

I'm a letter carrier looking for a quality rain jacket to keep me dry in spring showers or pouring storms, all through the New England seasons. Could you please point me in the right direction? Michael Springfield, Massachusetts

On a recent winter excursion in the Adirondacks, my Whisperlite stove failed. The fuel was pressurizing, but it wasn't reaching the ignition wick due to a blockage in the fuel line. Why does this happen in cold weather (our temperature was in the single digits), and how can it be prevented? John Buffalo, New York

I'm beginning to think that today's trend toward Assos-esque padded cycling shorts—padding formerly being the saddle's job—has left me with more saddle sores. This bulky new style only serves to form a bulk of soggy material once the sweat soaks through, causing blisters and general discomfort. Does anyone make shorts or bibs with either minimal padding or something akin to the original chois style? Between the incontinence of infancy and agedness, I prefer not to wear a diaper while riding. Can you help? Clay Wimberley, Texas

I have been backpacking and hiking for many years but I was recently told that for long hikes I should put on my liners, spread Vaseline on them, and then put on my hiking socks. Do you know anything about this or is this a joke? Joaquin Lira Oshkosh, Wisconsin

I'm going trekking around Mont Blanc and have been told not to drink any glacial meltwater because it contains tiny sharp particles of rock, called talc, which can shred one's insides. I have an Aquira water bottle with a two-micron filter, which is supposed to remove microscopic pathogens. Will it stop talc? Hal Berkeley, California

I've been shopping for a car-camping tent for our family (myself, my husband, two kids aged 14 and nine, plus one growing golden retriever puppy). I want a three-season tent that gives us a fair amount of space, maybe with dividers, but the mind boggles with all the choices: nylon, polyester, taffeta, fiberglass, aluminum, this D mesh, that D mesh. I feel like I need a degree in materials engineering to figure this out! Can you help? Tracey Irvine, California

Sage of swag, I'm in the market for a road bike, and looking for direction. Initially, I'll be using it for fitness riding, but I anticipate riding in local road races in the future. I'm a family man with a limited budget for recreational toys. That said, I want something that's going to stand up—a bike that I won't have to replace or extensively or upgrade as I get into the sport in a bigger way. Is a bike equipped with Shimano 105 group the "minimum" I should be looking at? Which models should I be considering, and at what price point? Greg Basky Saskatoon, Saskatchewan, Canada

I'm planning a through-hike of the Continental Divide Trail this summer, and I want to go ultra-light. What's the best tarp to use—the easiest to set up, the best in wind, and so on? Syd Seattle, Washington

Great burning bush of the gear desert, Marmot Precip hat or urban sombrero? I want to buy a good waterproof hat; hoods are cool and all, but they're sometimes a pain in the fanny pack. I have read that you often prefer hats to hoods. So, would you choose the Marmot Precip Safari Hat, the Outdoor Research Seattle Sombrero, or something different altogether? Please help me before I do something dumb—like ask someone else. Jay Eugene, Oregon

I'm a big guy (six feet five, 270 pounds) who's interested in buying a hybrid bike for some urban biking and trail riding (nothing too extreme or competitive). So I need a bike that fits but doesn't cost a fortune. Also, can you explain mountain- and hybrid-bike sizing conventions, especially as there doesn't seem to be a standard way of measuring hybrid bikes?

As a thrifty person with only occasional needs for real cold weather gear, I'm tempted by the down jacket that Land's End sells for $70. Pretty simple design, 650 fill, seems like something that's pretty tough to screw up. Any experience with how this jacket stands up to some of the pricier down parkas from the more traditional gear makers? I'd be using it for an around the cp and belay over-jacket in the Sierras. Raymond Tarto Oakland, California

I want to buy a bike to ride the two miles to work and head downtown on the weekends, about a 15-mile ride. Thing is, I have an attachment to big comfy handlebars, seats, and three-speed internal gears; I cringe at all the "touring" bikes with their rock-hard seats and hunched-over handlebars. I currently have a cruiser and walk it up hills. Can you recommend a bike that won't break the bank? Tiffany Santa Barbara, California
