if you have a 8 speed cog and a "supposedly" 10 speed crank? Thinking of getting the 105 5650 compact crank, I've got a 8 speed now, but plan to upgrade over the next several months. Just want to make sure if it'll cause any issues, or collect all the parts first before doing the swap. But it's not easy having a new part, and not putting it on. lol
