Rims from Triton Cycles

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, 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. The Arch MK4's BST-Asymmetric shape improves the 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. Stans 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. Versatile 28mm internal rim width optimised for 2.2-2.5in tyres Light and durable 6069 aluminium with welded joint and reinforced spoke bed BST-Asymmetric design combines Stans legendary easy tubeless inflation with a stronger, more balanced wheel build 3-year rim warranty with 1-year crash replacement

Stans Crest MK4 Rim - 29" / 700c

Crest rims are part of the history of mountain biking. Introduced in 2005, the Crest's design evolved directly from Stans earliest ideas, including the legendary 355 rims. Stan wanted a simple and durable rim that would work well without a tube and weighed less than everybody else's rims. The Crest achieved those goals. With a more durable and lighter 6069 alloy and an asymmetric rim shape that balances spoke tension, today's Crest MK4 has technology that's lightyears ahead of the early design, but the spirit of the original Crest lives on: make it light, make it serviceable, make it resist flats, and make it go as fast as possible. The BST-Asymmetric rim design of the Crest MK4 allows for a stronger wheel while offering easy inflation and Stans trademark unmatched airtight seal. The Crest MK4 rim is optimised for 40mm Gravel tyres and up to 2.3in mountain tyres, making it a great, versatile choice for a wide range of bikes and riding styles. The durable but forgiving ride of the Crest MK4’s 6069 alloy construction and lightweight, low-profile rim shape offer an unbeatable ride quality uniquely suited to Gravel and short-travel XC riding. Like all rims that bear the Crest name, it’s built for speed. The Crest MK4 combines the heritage of Stans legendary tubeless design with today’s best materials and a stronger asymmetric design.
