I'm building a new set of wheels which will be general purpose for my cross, commuting, light touring, nasty weather road riding bike. Do I go with a regular width road rim like the mavic CXP22, or should I go with a wider and heaver rim like the A719? I want to be able to run 32mm wide tires. I already have a road bike with light wheels/narrow tires for the good pavement / fast rides. It there a benefit to the wider rims or is it just extra weight with no benefit? Your thoughts and advice are much appreciated.
