Ratchet Upgrade Options


The ratchet upgrade option is a good choice for those who want a smoother feel at the pedals and quicker power transfer to the wheel. This is especially true for those running larger cassettes.


With the standard 18 tooth hub ratchet, there are 20° between each point of engagement in the freehub body. This means that there can be over 2 chain links before the hub engages on larger, 42 tooth cassettes. The 54 tooth ratchet upgrade improves the hub engagement to less than 1 chain link on 42 tooth cassettes.
