G Sport Ratchet Hub
The Ratchet hub is the current rear hub. You shouldn’t call it a cassette, there is no cassette of cogs here, just a rock solid one-piece driver. Every component has been designed from the ground up to be as smooth and solid as possible. The 3 pawls and ratchet ring are oversize, and because the driver and hub both run on the famously stiff 20mm GSport axle, everything will always be held in strict alignment. 3 independent long-travel springs keep the tension. The spring and pawl retention system ensures optimum alignment of pawls and drive ring, and keeps the hardware securely in place during routine maintenance. The oversize ratchet ring with patent pending square tooth profile makes for easy left/right drive switching, with no extra parts and virtually no tools.
