Right now about 215 lbs riding this (custom ti) with 32h Stan's No Tube rims. Can't remember which ones though. Hand built around CK hubs. Never had wheel problems, although the hub cracked and CK warrantied it. DA 9000.
Don't drool.
When touring, I carrying a lot of weight on this. 36h Alex Adventurer. New had any wheel problems even though I have taken it on some rough, hilly/mountainous, unpaved roads. Into its 8th season. Also serves as my commuter/errand bike.
