Designed to tackle technical terrain everywhere from Montana's winding wooded trails to the rocky mesas in southern Utah's desert, the Stans Flow MK3 27. 5in Wheel brings you the ideal combo of stiffness and strength for powerful riders who salivate at the idea of attacking some of the world's gnarliest terrain. As strong as it is light, the Flow MK3 27. 5in Wheel utilizes 6069 alloy construction for a bit of weight savings without sacrificing its legendary strength, while internal rim width puffs out to a 29mm platform built to pair with tire widths ranging from 2. 35 to 2. 8in. Since Stans is a tubeless pioneer, it's not surprising that the Flow MK3 with Bead Seat Technology (BST) brings you a proper seal and secure fit without worrying about burping issues when you're railing corners at high speeds and crushing across rock gardens. The Flow MK3 rims are laced to Stan's new Neo hubs, which feature oversized, smooth-spinning bearings that glide on a strong, stiff, swaged axle. The Neo holds the bearings at a wider stance for a claimed threefold increase in strength compared to standard hub designs, and it utilizes four precision pawls that simultaneously bite into a forged-steel 36-tooth ratchet ring for snappy, ten-degree engagement. Stan's built in its new SealLock end caps for easy installation and Slip-Fit axle ends for easy conversion.
