Notubes Flow S2 Shimano HG

Based on the legendary Flow rims that have won World Cup downhill events and the Enduro World Series, the Flow S2 wheel sets are an excellent upgrade for riders looking for better tubeless performance and great durability. The patented Bead Socket technology makes tubeless inflation easier and boosts confidence on the trails. A focus on durability means a reinforced spoke bed with eyelets, a quality rim strip with sleeve, and a 6061 alloy construction. An internal width of 30 mm makes the Flow S2 an ideal choice for tires ranging from 2.3 to 2.6 inches.

Durability, serviceability, and value are the three priorities around which every E-sync hub is built. From chromoly steel axles and double-row Enduro bearings to heat-treated steel ratchet rings and a ratchet design that reduces stress on the freehub and bearings, every detail of the E-sync hub is designed for durability. The E-sync hubs are also designed for quick engagement, with four pawls requiring only 8.18 degrees of rotation to engage simultaneously and transfer power to the ground. These hubs are perfect for e-bikes and riders who demand stronger components while still wanting the quick engagement of a high-performance hub.

The Flow S2 wheel set is available with a Shimano Micro Spline, HG, or SRAM XDR freehub, and a 6-bolt brake style, with options to accommodate all popular axle configurations. Ready for tubeless with pre-installed rim tape, the S2 wheels are built to last but also designed to be easy to maintain and update as axle and cassette standards evolve. Traditional J-bend spokes and lacing have a proven track record of ride quality, durability, and serviceability, and the matched S2 wheel sets all use a single spoke length, making it even easier to own and maintain your S2 wheel set for years. The Flow S2 with E-sync hub is the perfect wheel set for riders who value durability and tubeless performance.
