Product Details

The original Flow was light, wide, tubeless, and strong as hell. It redefined mountain bike rims and played a role in the evolution of riding. Today's Flow MK4 continues the progression with a 30mm wide asymmetric rim designed to build an even stronger overall wheel.

The Flow MK4’s 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. The Flow MK4's BST-Asymmetric shape is designed to equalize resistance to dents and tire bead retention on both sides of the rim under even the worst rock gardens and hardest cornering. Combined with Stan's patented Bead Socket Technology, the Flow MK4 rim offers the easiest tubeless setup and most reliable airtight performance on the trail.
