I'm at the point where I attach the chain (a 7/8 speed shimano hyperglide) to a new build up. The drive train is an 8-speed with an alivio triple. I'm not sure how to get the right length. Do I put it on the biggest ring and biggest cog (after threading it thru the derailer)? Or the middle cog and middle ring? Or what exactly?
Any tips much appreciated.
