Stan's NoTubes ZTR Crest 29" rims are lighter than the Arch and built for cross country and light trail use. The Crest 29" rim is a go to choice for building a light and reliable 29er wheel. We have build many sub 1500-gram 29er wheelsets with DT240 disc hubs, DT Aerolite spokes, alloy nipples and ZTR Crest 29er rims.

Notubes rims are made without a bead hook which allows the sidewall of the rim to be reduced by 2-3mm reducing rim weight and providing several other advantages. Some of this material can be relocated in the center part of the rim making it stronger and stiffer. By lowering the sidewall of the rim mechanical leverage the tire has on the rim is reduced. This will make the rim stiffer and last longer by eliminating flexing that can cause cracking. With these short sidewalls the tire should not hit the rim and pinch flat as often as standard rims, either with or without tubes. This design will allow you to run lower pressures and use 4mm more of the tire than ever before. The tire will have larger air volume giving you better traction versus any other rim in the world.

A result of blending a ZTR Race rim with a ZTR 355, the ZTR Crest is the best of both worlds. All the wall thickness and corresponding durability of a 355 with the next generation bead socket technology provides the tire stability and tubeless seal while creating a wider rim cavity with shorter sidewalls. The Crest 29" rim can be used with or without tubes. Requires 21mm or 25mm Stans Yellow tape and a value stem for tubeless (sold separately).
