Here's my recurring nightmare: I'm hurtling down a hill when my rim, worn away by repeated gritty brakings, ruptures and warps, stopping the bike instantly and launching me over the handlebars for a high-speed, unscheduled appointment with the pavement. So far, this has only happened in real life while I've been pedaling uphill. But, have any manufacturers come out with a road bike with disc brakes? I know they're heavier, but I don't care about weight if I can save skin and teeth. Mark Portland, Oregon
So, Mark, how about this: Replace the rims before they GET to the point where your nightmare becomes real. You wouldn't even need to do it that oftenone of my bikes is an Eddy Merckx that's now about eight years old. Sure, the front rim got tacoed in a crash five years ago and needed replacing, but the back rim is still the original. Thousands of miles on it, and still goong strong. Even the wheels on my rain bikea veteran of wet, grit, and the pressure of V-brakessurvived four years before I replaced them, and that was because the non-Shimano/non-Campy hubs sucked.
Still, for $1,500 you could replace your rims every three years for the next two decades, so there is that to chew over before you rush out and slap down a grand and change.
