Flow Mk4 Rim

The MK4 is the latest incarnation of the legendary Flow MTB rim from Stan's No Tubes, featuring an asymmetric rim profile and 30mm internal width, and continues the progression of a mountain bike rim that has played a role in pushing the boundaries of mountain bike riding.

The 6069 Aluminium alloy rim features a reinforced spoke bed, BST-Asymmetric shape and 3mm offset spoke drilling to not only provide a more proportioned and even spoke tension, but to equalise the resistance to dents and improve tyre bead retention to keep you rolling through the toughest rock gardens and hardest cornering.

The low profile design and 30mm internal width is said to optimise the tyre's shape and improve traction, control and feedback while reducing pinch flats, allowing you to push harder and ride even better, with confidence. Designed for All-Mountain, Enduro and DH applications, the MK4 has been optimised for use with 2.3-2.6" tyres.

Who's this item for: Trail, All-Mountain, Enduro and DH riders wanting a tough aluminium rim that will build into a super-strong wheel with even spoke tension and excellent tubeless bead retention.

Tubeless: Most definitely, from the pioneers of tubeless MTB technology. The Flow MK4 features Stan's patented Bead Socket Technology for super easy tubeless inflation and best in class bead retention.
