Stan's No Tubes ZTR Flow MK4 29" RIM

Since 2007, the Flow rim has helped riders around the world progress, pushing boundaries and pushing the boundaries of what is feasible on their bikes.

The original flow was light, wide, tubeless and stable. It redefined enduro mountain bike rims and played a role in the evolution of this type of wheel. The current Flow MK4 relies on a rim bed with 30 mm inner width, asymmetrical profile for even spoke tension and the patented bead socket technology for the easiest tubeless setup and the most reliable, airtight performance on the trail.
Longevity and an almost uncanny sense of control on the trail have made Flow rims the preferred choice for many Red Bull Rampage riders, and the Flow MK4 goes even further. The reinforced spoke bed of the Flow MK4 in combination with the offset holes of the asymmetrical design results in an incredibly durable wheel that provides additional confidence every time you ride.
Unlike many other asymmetrical rims, the BST asymmetric shape of the Flow MK4 is designed to provide the same resistance to dents and tire beading on both sides of the rim, even in the worst rock gardens and toughest corners.
