Tairin R1 Hook Flange Rear Hub - 6-Bolt - 12x142mm

Tairin R1 Hook Flange Rear Hub This is the new Tairin hub, with the modular magnetically ratcheting R1 drive configuration. It features ring gears that are preloaded to ratchet with attracting and repelling magnets. The magnets are designed to attract the gears together so that their magnetism is strongest when engaged in torque transfer, and lowest during ratcheting to reduce freewheeling drag, which is the opposite of a spring system. With only one moving part, and magnets that don't fatigue in preload, it is almost service free. The Tairin hub can be disassembled without tools, and the drive unit is removable with a tire lever. The Tairin hub can swap between the S1 and R1 drives without tools (the silent S1 drive kit is not included and can be purchased separately). Convertible between most axle standards, we have 4 platform models: -Standard: that can be converted between: 12x142mm, 10x135mm, 12x135mm (on request) and boosted with a kit to 12x148mm -Boost: (native at 12x148mm) tha
