Am considering upgrading the wheels, there are some decent Shimano race wheels around the traps from what I can see, just wondering if I get a narrower wheel, will the brakes on the bike at the moment work properly with these? I'd guess the sidewalls of the current braking surfaces on my wheels are about 2.5cm apart, the racing wheels look to be closer to 1.5cm... They usually have much narrower brakes on the bikes running these wheels right?
Any suggestions/comments welcome
