Friedpiggy Posted March 21, 2016 Posted March 21, 2016 I currently ride an 8 speed cassette with 12-21. I just saw a mtb 11 speed 11-42 cassette in the classifieds and was curious about compatibility with a road bike. Short version, could one use a mtb rear derailleur and cassette on a road bike?
Brother Brett Posted March 21, 2016 Posted March 21, 2016 Hi, It is possible to run a mtb rear mech and cassette on road bike but you will need same speed shifter. Furthermore to run 11 speed you would need 11 speed compatible wheelset. Most older wheels are 8,9 or 10 speed. If you are looking for easier gears perhaps run a triple chainset upfront? Or change to 8 speed mtb rear mech and cassette on rear. Good luck.

David Marshall Posted March 21, 2016 Posted March 21, 2016 You see quite a few tandems running Shimano MTB RDs and cassettes with road shifters - 8-10 speed. I think I read some where that 11 have different pull ratios. However I doubt that you will find an 8 speed RD that will take a 42 cassette.
Friedpiggy Posted March 21, 2016 Author Posted March 21, 2016 Was thinking of how easy hills would be with a 30 front and 42 back.
