Stan's No Tubes ZTR Arch MK4 29" RIM

In the ten years since the first Arch rim appeared, mountain bikes have continued to evolve. They are longer, flatter, and more aggressive than ever. In order to meet the new requirements, of course, the Arch in the MK4 version also had to be adapted to the new challenges. In the rim bed measuring 28 mm inside width with its flat rim horns, tires of 2.2 "- 2.5" sit perfectly formed and airtight in place. The asymmetrical BST design with 2.5 mm offset of the spoke holes allows an evenly tensioned impeller that withstands any outrage thanks to the robust 6069 aluminum alloy. At 481g in 29 ", the rim is light enough for XC races, but thanks to extensive development work it is also robust enough for use in the Enduro World Series.

So it doesn't matter whether you want to drive your next XC race, plunge down rocky slopes or just want to enjoy your extended Sunday tour. The Arch MK4 is ready.
