Rim Features:

• This new rim design eliminates the traditional bead hook and uses our new bead socket technology™. It moves 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.

Yellow Spoke Tape: The ZTR 355, is 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 NoTubes 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.

Note: This rim has a small inner valve stem hole to allow use with the small 5g valve stem in conjunction with the 21mm yellow tape. If you are using a UST tire don't use the rim strip, use only the yellow tape. If you want to use the Olympic rim strip you can use it with the hole that comes with the rim, but you will have a large bump at the valve stem that will make inflating with a floor pump more difficult. If you want to use the Olympic rim strip and inflate tires easily with a floor pump you should enlarge your inner rim cavity hole to 3/8 inch. Keep in mind, once you enlarge the inner valve stem hole to use the rim strip you can no longer use the small 5g valve stem, as the inner rim cavity hole will be too big.
