Since 2007, the Flow rim has helped riders make progress, push boundaries, and achieve more on their bikes. The original Flow was lightweight, wide, tubeless, and very stable. It redefined mountain bike rims and played a role in the evolution of riding. The current Flow MK4 continues this development with a 30 mm wide, asymmetrical rim designed for an even more stable wheelset. Durability and an almost uncanny feeling of control on the trail have made Flow rims the preferred choice for numerous Red Bull Rampage riders, and the latest Flow goes even further. The reinforced spoke bed of the Flow MK4, combined with the offset drilling of the asymmetrical design, results in an incredibly durable wheelset that provides extra confidence with every ride. Unlike many other asymmetrical rims, the BST-Asymmetric shape of the Flow MK4 is designed to offer the same resistance to dents and tire bead formation on both sides of the rim, even in the worst rubble and tightest corners. Combined with Stan's patented Bead Socket Technology, the Flow MK4 rim offers the easiest tubeless setup and the most reliable airtight performance on the trail. Enhance your progress and make every ride even better with the confidence of the asymmetrical Flow MK4 rims.
