Details of the Stan’s NoTubes Flow MK4

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.

Each detail of the M-pulse hub was engineered to systematically eliminate weaknesses found in other designs. The 17mm axles are made of 7075 aluminum and roll on Enduro brand bearings. The entire hub is also shielded, meaning no bearing seal is visible, offering superior protection for all conditions. Beyond the strength and speed of engagement, M-pulse hubs feature adjustable preload, allowing a tremendous decrease in drag for less resistance and more speed.
