Whether you´re navigating technical singletrack, charging down enduro stages, or sending it at the bike park, this rim provides the perfect balance of strength, weight, and stiffness to elevate your mountain biking experience.The Flow MK4 is built on a foundation of proven Stans NoTubes technology, refined for the modern rider. Its generous 30mm internal width creates a superior tire profile, optimized for tires ranging from 2.3´´ to 2.6´´. This WideRight design ensures your tires have the ideal shape for maximum traction in corners, improved climbing grip, and lower rolling resistance on the flats. You´ll feel more connected to the trail than ever before, with predictable handling that inspires you to push your limits.At the heart of the Flow MK4 is the innovative BST-Asymmetric rim design. This intelligent shape offsets the spoke holes, allowing for more even spoke tension between the drive and non-drive sides of the wheel. The result is a significantly stronger, stiffer, and more reliable wheel build that can withstand immense forces without flinching. Coupled with Stans´ legendary Bead Socket Technology, setting up your tires tubeless is incredibly simple and secure, giving you the benefits of lower pressures, increased puncture resistance, and a smoother ride.Enhanced Durability for Your Complete Wheel SystemToday´s trails and riders demand more from their equipment than ever before.
