I bought this primarily for the chain catcher. My 10 speed Rival front derailleur had a propensity to drop the chain on the downshift. The new Force 22 is totally compatible with the rest of my 10 speed set up. However, I still need to use the trim function on the shifter to avoid chain rub. The YAW technology does not solve that issue, at least not worth my set up. The shifting is much lighter and smoother. Well worth the upgrade.
