    Would You Trust These Wheels?

    I just picked up my Trek Ion CX Pro yesterday and love the bike but did not put many miles on it yet. I wanted to get some feedback on the wheels before I ventured too far from home.

    I will be doing almost all smooth flat road just putting miles on, nothing extreme at all. I am 330 lbs and not sure if the wheels should be upgraded or I should give these a try first.

    I am not sure what happens when a wheel fails, do spokes break, does it slowly go out of round or does it just colapse?

    I hope to be under 300 lbs soon but do not want to be riding along and have a wheel just bend so hopeing to get some good advice from those of you who know more about them.

    Wheels should work if you ride on smooth roads. Bring the wheels to a good shop to make sure the spokes are properly tensioned and stress relieved.

    I would not go for a lightweight bike with low-spoke count wheels if I was over 250 lbs. An older Cr-Mo steel frame with 32c or larger tires would give you better handling and greater comfort.

    I've had some reduced spoke wheels that were bomb-proof (Rolf Vector Comps) and some reduced spoke wheels that were crap (Mavic CXP-22 rims). The crap rims would wobble, shimmy and vibrate. BTW: I weigh 220 lbs.

    I've had excellent results with both Mavic CXP-33 and Mavic Open Pro rims with 32 spokes.

    As far as failure, chances are that if those wheels give you problems, it will be with going out of true easily or a spoke or two popping. Then you should consider getting different wheels.

    However if you ever experience a 'speed wobble' where the bike is about uncontrollable, those wheels could be the problem. If you ever have such a wobble, I wouldn't ride that bike again until the problem is fixed. Of course it might not be the wheels, but it could be.

    Lastly there is a condition where a wheel can 'taco' all at once. This is very rare and I doubt that it happens to you.

    Thanks guys, I went with the better race wheels not for light weight, but thinking for a cyclocross bike, they would be made for taking a beating. I don't plan on jumping on and off the bike, or bunny hopping like many riders may.

    I can't wait until I am no longer concerned about failure due to user weight.
