Notubes Flow MK4 rim 29", 28 hole

Since 2007, the Flow rim has been helping cyclists make progress, push their limits, and achieve more on their bikes. The original Flow was lightweight, wide, tubeless, and incredibly stable. It redefined MTB rims and played a role in the evolution of cycling. Today's Flow MK4 continues this evolution with an asymmetric rim that is 30 mm wide, designed to create an even more resilient wheel. The durability and almost unbelievable control on the trails have made the Flow rims the preferred choice for many Red Bull Rampage riders, and the current Flow takes it a step further. The reinforced spoke bed of the Flow MK4, combined with the offset drilling design of its asymmetric construction, results in an incredibly durable wheel that instills more confidence on every ride. Unlike many asymmetric rims, the BST-asymmetric shape of the Flow MK4 is designed to equalize resistance to impacts and the seating of the tire bead on both sides of the rim, even in the worst rock fields and the most challenging corners. Combined with Stan's patented Bead Socket technology, the Flow MK4 offers the simplest tubeless setup and the most reliable waterproof performance on the trail. Accelerate your progress and enhance every ride with the confidence of the asymmetric Flow MK4 rims.
