Enhance your mountain biking experience with the versatile and durable Flow MK4 wheelset. Since 2007, top riders worldwide have trusted Stan’s for reliable, high-performance rims. Designed for aggressive trail riding, the Flow MK4 allows you to corner harder, send jumps further, and maintain higher speeds through challenging terrain. Its patented BST-Asymmetric rim shape ensures a superior tubeless seal, while the robust 6069 alloy construction and reinforced spoke bed deliver exceptional durability. The unique asymmetrical design enables the use of a single spoke length on both front and rear wheels, simplifying maintenance and ensuring consistent strength.

At the core are M-pulse hubs, featuring magnetic locking engagement for smooth, reliable performance. Based on the innovative Project321 system, these hubs offer quick, precise engagement with six Neodymium magnets, providing minimal resistance during coasting and maximum power transfer when accelerating. Crafted from 7075 aluminum with Enduro double-row bearings, the hubs are sealed for all-weather protection and feature adjustable preload for reduced drag and increased speed. Compatible with Shimano Micro Spline, HG, or SRAM XDR freehubs, and available in 6-bolt or Centerlock configurations, these wheels are ready for any setup.

The tubeless-ready rims come pre-installed with rim tape, combining a 30mm internal width for optimal tire shape and traction with lightweight, welded 6069 alloy construction. The BST-Asymmetric design ensures easy tubeless inflation and a balanced wheel build, making every ride more confident and controlled. Perfect for 2.3-2.6” tires, these wheels deliver strength, speed, and reliability across all trail conditions.
