Stans No Tubes Arch MK4 MTB RimThis 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 Stan's 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 RimMountain 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, today's 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.Strong, Lightweight and Durable Asymmetric DesignThe 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 equalize pressure for easy inflation and incredibly strong tyre retention on both sides of the rim.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.Features: Material: 6069 Aluminium Alloy Use: Mountain Bike (MTB), Cross Country (XC) Brake Type: Disc only Hole Count: 32 hole Rim Width: Internal: 23mm; External: 31.4mm; Depth: 18.9mm ERD: 27.5" Option: 561mm; 29" Option: 600mm Offset: 2.5mm Valve: Presta Single or Pair: Single Weight: 27.5": 451g; 29": 481gTechnologies: Versatile 28mm internal rim width optimised for 2.2-2.5” tyres.
