STANS NO TUBES Flow MK4 29´´ RimDominate every trail with the legendary STANS NO TUBES Flow MK4 29´´ Rim, the next evolution in high-performance MTB Cycling. Born from a legacy of trail-taming strength and innovation, the Flow MK4 is engineered for riders who push their limits. This rim is the go-to choice for all-mountain adventures, enduro racing, and aggressive trail riding, offering an unbeatable combination of control, durability, and the world-renowned tubeless simplicity that defines Stan´s NoTubes.The Flow MK4 is built to inspire confidence on the most challenging terrain. Its wide and low-profile design provides exceptional stability and helps prevent pinch flats and rim damage from rock strikes. This modern design, combined with Stan´s patented Bead Socket Technology (BST), ensures a secure, reliable, and incredibly easy-to-inflate tubeless setup, allowing you to run lower pressures for phenomenal traction and cornering grip.At the heart of its superior performance is the BST-Asymmetric design. This intelligent feature offsets the spoke drilling, which improves the spoke bracing angle and allows for a much stronger, stiffer, and more reliable wheel build by balancing spoke tension between the drive and non-drive sides. This means your wheel stays truer for longer, even under the punishing demands of aggressive MTB Cycling. The WideRight rim profile is optimized for 2.3 to 2.6 tires, ensuring your tire maintains the ideal shape for maximum traction, minimal rolling resistance, and predictable handling.
