This mountain bike (MTB) rim features a robust 6069 aluminium alloy build that makes it tough and dependable as you hit the trails. Stans No Tubes has also equipped this model with a BST asymmetric design which combines Stans legendary easy tubeless inflation with a stronger, more balanced wheel build. As a result, you’ll enjoy tubeless benefits such as the ability to run lower tyre pressures for increased stability on rough terrain, low rolling performance and fewer risks of flats or punctures. This makes it a great choice for completing your next wheel build or for upgrading your existing stock rim.

Tubeless Ready MTB Rim

Mountain bikes have changed in the decade since the original Arch rim helped introduce the world to tubeless technology. With a 28mm wide asymmetric rim shape and ultra-strong 6069 alloy, todays Arch MK4 rim has evolved to match these more capable bikes. Through all the years of testing and refinement of this rim, one thing has never changed: versatility. Now more than ever, when you want a reliable rim that can handle every trail, the Arch MK4 is for you.

The Arch MK4 rim is light enough to take XC racing but was born from research and testing on the Enduro World Series circuit, making it a great rim for anyone looking to improve both descending and climbing. Constructed of light and strong 6069 aluminium alloy, with a reinforced spoke bed and 28mm internal width ideal for 2.2-2.5 tyres, the Arch MK4 can get you up the climbs easier and make the descent even better.
