This is also considering you swap out the cogset from 12-25 to 11-23.
Probably. Assuming you're using a short cage rear derailleur you are going to be pretty close to your derailleur's capacity to wrap up chain. If your chain is longer than it needs to be, it might well be too long. When I installed mine I resized the chain using the big/big method and took out 1" (2 links) of chain.
