Stans No Tubes Flow Mk4 32 bolts rim

Increase your progression and improve every ride with the safety of Flow MK4 asymmetrical rims

Since 2007, Flow rims have helped cyclists progress, push the limits and do more with their bikes. The original Flow was light, wide, tubeless and incredibly strong. It redefined mountain bike rims and played a role in the evolution of riding. The current Flow MK4 continues this progression with a 30mm wide asymmetrical rim designed to build an even stronger wheel overall. Durability and an almost extraordinary feeling of control on the trails have made Flow rims the preferred choice of many Red Bull Rampage riders, and the current Flow goes even further. The Flow MK4's reinforced spoke bed, combined with the offset drilling of the asymmetrical design, creates an incredibly durable wheel that brings more confidence on every ride. Unlike many asymmetrical rims, the Flow MK4's BST-Asymmetric shape is designed to equalise the tyre's dent resistance and bead retention on both sides of the rim, even in the worst rock gardens and tightest corners. Combined with Stan's patented Bead Socket technology, the Flow MK4 rim offers the easiest tubeless setup and most reliable airtight performance on the trails.
