Super smooth pawls system

Why we chose the pawls system instead of the ratchet system? Please note that this is not an normal pawls system. According to our experimental results, The 36T ratchet system has approximately 1.47N rotation resistance, our new 4 pawls system as approximately 0.343N rotation resistance. This means that the running resistance of the hub body has dropped by 76.6%!

Not only smooth, but also fast

In the world of road bike, every watt of power waste is unacceptable, so we decisively chose the new system, and we also divided them into two groups to make it reach 72 click/round. (36T x 2 Group)

XDR/ HG-11/ CP compatible

You can install any Road bike Cassette with this hub.

if you need to install 8/9/10 speed HG standard cassette, you need add a 1.8mm spacer.
