I recently bought a Trek DS 8.4. My rides are usually 10 to 12 miles on paved trails, once or twice a week, with a goal of riding similar distances 5 days a week - gotta get up earlier so it doesn't interfere with work and family. I hadn't though much about my weight being an issue (270lbs) for the bike until I read something about wheels wearing out for heavier riders. My rides have some hills, but no bumps or jumps. I'm wondering how concerned I should be, and if there is anything else I need to take into consideration.
