What do I do if my front derailleur hanger is too short for my road bike project?
EDIT: My derailleur hanger is too LONG... I have an 88 Miyata 512 frameset that I built up with a full SRAM Rival groupset.
When I initially finished the build I could not shift into the lowest (inner) cog on the rear derailleur without the chain rubbing the inside of the front derailleur cage. The lower limit screws are set as low as they can go, their is no cable tension, and it still rubs. Someone mentioned that I should put an extra spacer on the crank side to move the chainrings in which IMO would solve the problem but then I would not be able to fully tighten the crank arms together without crushing the bottom bracket? Any ideas on how to cure the chain rub?
P.S. I tried rotating the rear of the front derailleur in towards the frame which stopped all rubbing but then I repeatedly got chainsuck that left the chain locked between the outside of the front derailleur and the inside of the front chainring.
