NoTubes ZTR Arch 29er Disc Rim

Designed for aggressive cross country use

  • FEA optimized centre arch increases stiffness more than 20% over the ZTR 355
  • Unmatched strength to weight ratio for a cross country rim
  • Welded joint
  • Black anodized finish
  • This is NOT a tubeless (UST) rim. The appropriate tubeless rim kit must be purchased separately before running tubeless a set up.

Bead Socket Technology:

  • 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 tyre 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 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 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 tyre than ever before. The tyre will have larger air volume giving you better traction.

ZTR Arch 29er :

  • ISO - 622x19
  • ERD - 604 mm
  • Weight - 470g

Note: This rim has a small inner valve stem hole to allow use with the small 5g valve stem in conjunction with the 25mm yellow tape. If you are using a UST tyre 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 tyres 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.

Rated 5 out of 5 by 1 reviewer.
Rated 5 out of 5 by Excellent rims for 29er xc Strong. Relatively light. Easy to build/true. Easy to set up and run tubeless, as you'd expect. A great rim if you use it for cross country. For free ride and downhill you'd want something a bit stronger (e.g. Flow). I'm running them tubeless with Stan's yellow 25mm rim tape, Conti Race King 2.2 and CaffeLatex goo. Use the Stan's valves, not the CaffeLatex. 27 July 2011
