Based on the legendary Flow rims that have won World Cup DH and Enduro World Series events, Flow S2 wheelsets are a great upgrade for riders looking for better tubeless performance and excellent durability. Patented Bead Socket Technology means easier tubeless inflation and more confidence on the trail. An emphasis on durability means a reinforced and eyeletted spoke bed, a quality sleeved joint, and 6061 alloy construction. A 30mm internal width makes the Flow S2 ideal for 2.3-2.6” tires. Low-profile 30mm internal width optimizes tire shape, traction, and control for 2.3-2.6” tires. 6061 aluminum with sleeved joint and stainless steel rim eyelets. Patented BST low-profile rim shape for easy tubeless inflation and the most reliable seal. Matched wheelsets use traditional J-bend lacing and share a single spoke length for easy serviceability. E-sync hubs feature Enduro bearings with double-row freehub bearing and cromoly axle offer 47% increase in max torque capacity over Neo hubs. Tubeless tape installed, requires additional valve stems. 32 Spokes.
