I recently bought a 1986 Cannondale SR500.
It has the original Shimano 600 MF6208 13-18 freewheel.
I would like to use an MFTZ20 14-28 freewheel (full part # is EMFTZ206428T).
Will that work? If not what should I use to get a larger freewheel?
Should I change the chain too? What chain?
Thank you for your input.
Jim
