I can't find a good mountain-biking seat that doesn't make me feel like I was violated after a long ride. One friend suggested stuffing my shorts with Vaseline. I ride a fair ount, and it's always pretty bad after a long one, but even a moderate 20-miler leaves me walking like I have a pole in the pipe for a day or two. What gives? What can I do? Jayson Los Angeles, CA

When a company like Specialized dreams up a new ride, design teams are deployed, test frames are destroyed, and the stakes are huge. With the 2009 Epic, the goal was suitably grandiose: to create the fastest, most responsive mountain bike around—and earn a world championship to prove it.

I'm looking for a backpack for commuting (note: I’m not interested in panniers). The ideal pack would have a ventilated back and expandable volume—some days it's just for work clothes, but some days I’ll throw in a book or my computer. Internal pockets would be good, and water resistance is a plus. I'd also like my Eagle Creek clothes organizer to fit inside. Is this too much to ask for? Dave Sierra Vista, Arizona

I'm looking for a bike to do a bit of everything: commuting year round, several short rides in spring, and some off-road racing in early fall. What's your opinion of the Gary Fisher 29er bicycles, and how exactly do they differ from other high-end hybrids (for exple, the Cannondale Bad Boy HeadShok or the Kona Dr Dew)?

Can one bike do it all? Jarle Bergen, Norway

Have I got an expensive proposition! I'm planning a trip to Italy and thinking it might be the perfect time to buy a new road bike straight from the factory, say Pinarello, De Rosa, or Colnago. Are there any advantages to doing this, such as incredible savings, or seeing the bike in progress and test riding it in the mountains? Are there drawbacks, such as duties, taxes, exchange rates, warranties and language that would make this way more trouble than it's worth? Thanks for your wisdom! Bob Foster St. Louis, Missouri

Do you know of any underwear or pants that could help fight this problem? Karl Rostock, Germany
