I'm fairly new to the biking, so this may be a stupid question. I purchased a used 1990 Cannondale 3.0 Criterium, and I need to change the rear cassette to make the bike easier for climbing.
I was in the process of switching out the 11/25 8 speed rear cassette for a 12/32 8 speed rear cassette, and discovered the new one doesn't fit!
The old cassette is a Shimano 600 8 speed, and was switching to SRAM 850 8 speed. The hub on my wheel is too big for the SRAM to fit! Aren't SRAM and Shimano compatible?
