Stans No Tubes Flow MK4 MTB Rim

Stans No Tubes Flow MK4 MTB Rim

This high-quality mountain bike (MTB) rim is engineered for fast and smooth-rolling performance, whether you’re shredding your favourite local trails with your riding buddies or exploring new mountain routes on your own. It features a rock-solid 6069 aluminium alloy build, which makes it more than capable of handling all the hits associated with modern trail riding. Thanks to its tubeless ready technology, you can enjoy tubeless benefits such as the ability to run lower pressure tyres for increased stability, comfort and fewer risks of flats or punctures. One final highlight is this model is disc brake compatible, which means you’ll benefit from power and consistent braking performance as you carve your way around the mountain.

30mm Wide Asymmetric Rim

Since 2007, the Flow rim has been helping riders progress, push boundaries, and do more on their bikes. The original Flow was light, wide, tubeless, and very strong. 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.

Tubeless Ready

Durability and an almost uncanny feeling of control on the trail have made Flow rims the preferred choice of multiple Red Bull Rampage riders, and today’s Flow goes even further. 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. Unlike many asymmetric rims, the Flow MK4’s BST Asymmetric shape is designed to equalise resistance to dents and tyre 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.

Ramp up your progression and make every ride even better with the confidence of the Flow MK4 asymmetric rim.
