Stans NoTubes Arch MK4 29" 32H Wheel Rim Black

Great Rim For Descending And Climbing
The Stans NoTubes Arch MK4 Rim is light enough to take XC racing but was born from research and testing on the Enduro World Series circuit, to be a great rim for anyone looking to improve both descending and climbing. Constructed of lightweight and ultra-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.

Strong Tyre Retention On Both Sides Of The Rim
The Arch MK4's BST-Asymmetric shape improves spoke angle, allowing for a stronger overall wheel build. Unlike most asymmetric rims that struggle with tubeless inflation and consistent airtight seal under hard cornering, the Arch MK4's shape is designed to equalise pressure for easy inflation and incredibly strong tyre retention on both sides of the rim.

Ready For Whatever You Can Throw At It
Stan's patented Bead Socket Technology, combined with a stronger asymmetric design, light and durable 6069 alloy, and the perfect rim width for balancing control and weight, make the Arch MK4 your best choice for all-around riding. Powering up rocky switchback climbs or slapping berms on every descent, the Arch MK4 is ready for whatever you can throw at it.
