Bombproof Velocity Deep V and Chukker wheels
If you are having trouble with breaking spokes or your wheels won't stay in true, these may be the answer. Riders weighing 200lbs or more, often have troubles with low spoke count wheels sold with many stock bikes.
The Velocity Deep V rim built with 32 or 36 hole hubs is a great solution. The rims build into a very stiff wheel that won't flex under the increased power loads bigger riders exert on their wheels.
If the Deep V isn't enough or you just want a wider rim, the chukker is the next step up in Bombproof wheels.
These wheels transfer power better and will stay in true without breaking spokes.
