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.

I’ve been riding these wheels for about a year now, and am in love! They make the flats feel effortless, and climb very well, and the disc brakes are awesome on mountain descents! I have a set of 25c tires and on these rims, they ride like 28s.
My FSX50.1s have proven to be a phenomenal wheelset and the deeper dish makes any bike look amazing. These wheels stand out against other carbon sets I’ve owned (Enve, Zipp). Forgiving and reliable. Extremely strong. No issues riding on bad roads, sand, grass, gravel or pot-holes.
