I already have a Shimano Sora groupset. I don't like the shifters or sprocket. I don't really want to spend a lot of money for a new complete groupset, so which components are absolutely required? Which is the least amount of parts I can get?
I have the Sora and I'm looking at the 105. The Sora is 9 spd and the 105 is 10 spd
