I recently replaced my bottom bracket and crankset and while tuning my bike up, I noticed that when the chain is on the lowest possible gear (biggest cog and smallest chainring), the chain rubs the inner part of the front derailleur.
The chain line for the crankset is 45mm and the front derailleur is also for 45 mm. The front derialleur
Both the front derailleur and the crankset are Shimano Soras but the front derailleur is front the last gen. one. However, seeing as the chainline is the same at 45 mm, they should both be compatible.
As for the limit screw, I've loosened it all the way but the problem still persists.
I'm thinking that I might possibly need bottom bracket spacers.
I'll try to measure my chainline later.
