If you're looking for more durability than a dedicated race wheel, check out the Easton EA90 SL Clincher Wheel. Leaning more to the heavy-duty side of things, the EA90 SL still slices through the air and spins up quickly, but—thanks to added spokes front and rear—it'll handle heavier loads than race-stock units.
I beat the round out of these but they stayed round. These wheels are solid. Great city wheel. Light enough to spin up fast, but strong enough to survive a beatdown. The aluminum freehub body is bad on witness marks. These would make a great trainning wheel if you can maintain the hub yourself.
