Stans Notubes Rim, Flow Mk4 29, 32h, Black / Gray

Since 2007, the Flow rim has been integral to enhancing rider capabilities, expanding boundaries, and elevating performance on bikes. The initial Flow was lightweight, wide, tubeless, and incredibly durable, revolutionizing mountain bike rims and shaping the evolution of the sport. The current Flow MK4 carries on this legacy with a 30mm asymmetric rim that further fortifies the entire wheel. With a reputation for lasting durability and unparalleled control on the trails, the Flow MK4 rim has become the top choice for numerous Red Bull Rampage riders. This latest version of the Flow takes things even further with a reinforced spoke bed and an asymmetrical design that boasts offset drilling, resulting in an impressively sturdy wheel that instills confidence on every ride. Unlike many asymmetrical rims, the BST Asymmetric shape of the Flow MK4 is specifically created to distribute resistance to dents and maintain tire bead retention on both sides of the rim, even in the toughest of rock gardens and corners. Additionally, the Flow MK4 rim, equipped with Stan's patented Bead Socket Technology, offers the easiest tubeless setup and the most dependable airtight performance on the trail. Elevate your riding and experience the enhanced assurance of Flow MK4 asymmetric rims.
