The long awaited and highly anticipated Seismic hub from Eclat is now available! Eclat have designed a brand new cassette TCS (Toothed Coupling System) mechanism which features 2 couple d toothed ratchet rings which are inside the hub and the driver. The two rings are pushed together with a very special design of spring, which allows the hub to transfer power in one direction, and freewheel in the other. Basically a much stronger internal mechanism, which can't fail even after years of heavy use. No more skipping, slipping or popping, you can really crank this thing as hard you want and it's not going to fail. Even after years of heavy use, this hub was designed to keep going on and on. 2 x Nylon Eclat Hub guards included. ###section### Product Specs HUB TYPE: AXLE: 14mm Male DRIVER: DRIVE SIDE: Left Side Drive SPOKE HOLES: 36h WEIGHT: 466.9g (1.03lbs) Colour: Silver, Black; Size: LHD
