DESCRIPTION:

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” tyres.

Durability, serviceability, and value: every E-sync hub is built around these three priorities. From chromoly steel axles and double-row Enduro bearings to special heat-treated steel ratchet rings and a pawl design that reduces stress on freehub and bearings, every detail of the E-sync hub is designed for durability. E-sync hubs are also designed for fast engagement, with four pawls needing only 8.18° of rotation to engage simultaneously and put power to the ground. E-sync hubs are perfect for eBikes and riders who demand stronger components, but still want the fast engagement of a high-performance hub.

The Flow S2 wheelset is available with Shimano Micro Spline, HG, or SRAM XDR freehub, and 6-bolt or Centerlock brake style, with options to fit all popular axle configurations. Tubeless ready with rim tape comes pre-installed. S2 wheels are built to last long, but also be easy to service and update with changing axle and cassette standards. Traditional J-bend spokes and lacing have a proven history of ride quality, durability, and serviceability, and matched S2 wheelsets all use a single spoke length, making it even easier to own and service your S2 wheelset for years. The Flow S2 with E-sync hub is the perfect wheelset for riders who value durability and tubeless performance.
