Stan's NoTubes ZTR Alpine Rim, 26" 32H

Stan's NoTubes ZTR Alpine 32H Rim

• Every other rim in the world has a bead hook. This rim does not.
• This new rim design will eliminate the bead hook and move the sidewall of the rim down by 2-3mm.
• 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 center 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 tire bead while creating a tighter seal.
• By lowering the sidewall of the rim we also reduce the mechanical leverage the tire 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 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 than any rim in the world.
• Can be used with or without tubes.
• Guaranteed less than 352g and usually are between 330 to 340gr.
