Notubes Flow MK4

With the Flow MK4 wheelset, you can achieve more. Since 2007, there’s a reason why the best riders in the world come to us asking for Flow wheels. You can take harder turns, ride further, and gain more speed through every section of the trail. The current Flow MK4 wheelset gives you the control you need to push your limits.

The patented BST-Asymmetric shape of the Flow MK4 rim provides the most reliable tubeless seals. The durable 6069 alloy and the reinforced spoke bed, combined with the offset drilling of the asymmetric design, result in an incredibly durable wheel.

The M-Pulse hub combines the best materials and constructions with an intelligent engagement system, designed to roll smoothly for longer. The heart of the M-Pulse hub is the magnetic locking system based on the innovative Project321 design, manufactured in a high-precision small-batch production. The M-Pulse freehub features six pawls equipped with neodymium magnets that engage with more force every 1.66° than traditional spring-based pawl designs, offering less resistance when coasting. With reduced friction and resistance, Stan's NoTubes provides a 5-year warranty on this convincing and durable technology!
