Stans No Tubes ZTR 355 Disc MTB White 32 Hole Rim

By eliminating the bead hook and lowering the sidewall by 2-3mm we reduce the weight of the rim. Some of this material can be used in the centre part of the rim making it stronger and stiffer. The curve of the rim sidewall is the same shape as the bead of the tire so they fit together like a ball and socket joint. This design will help reduce the strain on the tyre bead while creating a tighter seal.

By lowering the sidewall of the rim we also reduce the mechanical leverage the tyre has on the rim. This will make the rim stiffer and last longer by eliminating flexing that can cause cracking.

With these short sidewalls the tyre 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 tyre than ever before. The tyre will have larger air volume giving you better traction than any rim in the world.

The ZTR 355, is fully compatible with the 21mm yellow tape and valve method for tubeless use. Most riders elect to use the thin 5g yellow spoke tape and no rim strip. All wheelsets built by No Tubes will have the yellow tape and valve installed as standard practice. The tape and valve method creates a lighter wheelset and the rim design will allow you to run extremely low pressures with very little or no burping.
