I'm wondering if you guys can give me some advice. I live in New York City and recently gave up running due to knee problems. I planning to stay in shape by biking, mainly around the city and in the park. Anyone who's lived here knows that the roads aren't the smoothest around and can be downright punishing to a wheelset and your body. I'm considering a cyclocross bike because of its larger tires, which I'm hoping would help absorb some of the road noise before it reaches my rims, bike, and body. Lately, however, I've been wondering if it would be possible/feasible to upgrade a traditional road bike with somewhat thicker tires and stronger rims to withstand city streets on a regular basis. How does a decent set of rims like Rolf Vector Comps hold up in regular city riding (I'm 5'9" and 150lbs) and what are my choices for going larger with the tires?
I really appreciate your help!
