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 aluminum alloy, with a reinforced spoke bed and 28mm internal width ideal for 2.2-2.5″ tires, the Arch MK4 can get you up the climbs easier and make the descent even better. Utilizing Stan’s patented Bead Socket Technology, combined with a stronger asymmetric design for balancing control and weight, the Arch MK4 your best choice for all-around riding.

The Flow EX3 is the most reliable tubeless rim made for handling faster speeds on the most demanding trails. If you’re looking for the ultimate rim for Enduro and DH racing, something to handle the increased weight and added speed of an E-bike, or just want the most durable rim possible, this is it. The Flow EX3 combines the 29mm internal width and durable 6069 aluminum construction of the Flow MK3 with the incredibly strong triple cavity design of the classic Flow EX rim. The result is a new rim shape that perfectly balances radial compliance with lateral stiffness and sets an entirely new benchmark for durability and impact resistance.

Durability and an almost uncanny feeling of control on the trail have made Flow rims the preferred choice of multiple Red Bull Rampage riders, and today’s Flow goes even further. The Flow MK4’s reinforced spoke bed, combined with the offset drilling of the asymmetric design, builds into an incredibly durable wheel that brings added confidence to every ride. Unlike many rims, the BST Asymmetric shape is designed to equalize resistance to dents and tire bead retention on both sides of the rim under extreme conditions. Combined with Stan’s patented Bead Socket Technology, the Flow MK4 rim offers the easiest tubeless setup and most reliable airtight performance on the trail.
