DESCRIPTION:

The Flow MK4 wheelset lets you do more. Since 2007, there's a reason the best riders in the world have come to us to ask for Flows. Corner harder, send it further, and carry more speed through any section of trail. Today's Flow MK4 gives you the control you need to push boundaries.

The Flow MK4 rim's patented BST-Asymmetric shape creates the most reliable tubeless seal. The rim's durable 6069 alloy construction and reinforced spoke bed, combined with the offset drilling of the asym design, builds into an incredibly durable wheel that brings added confidence to every ride. Strength and serviceability are long-standing priorities of every Stan’s wheel, and the Flow MK4 wheel takes those priorities further than ever before. The asym rim design allows for a single spoke length to be used on both the front and rear wheels. As with all Stan’s wheels, traditional J-bend spokes and lacing are used for their proven strength, ride quality, and serviceability. 

Available with Shimano Micro Spline, HG, or SRAM XDR freehub, and 6-bolt or Centerlock brake style, with options to fit all popular axle configurations.Tubeless ready with rim tape installed.   

Wide, light, strong, and tubeless, the original Flow redefined what a mountain bike rim could do. Today's Flow MK4 gives you the confidence to do even more.

WHAT'S INCLUDED:

Flow MK4 wheels include pre-installed tape for tubeless use and presta valves.
