feetup Posted September 3, 2014 Share 24T Crank with a 36T Cassette VS 30T Crank with a 42T Cassette Will the granny gear be the same? Link to comment Share on other sites More sharing options...
Nibali Posted September 3, 2014 Share Quite close, but not strictly the same. The one gives a ratio of 0.67 and the other 0.71, so close enough I would say. Link to comment Share on other sites More sharing options...
NotSoBigBen Posted September 3, 2014 Share Also apparently a difference in how it feels, something about the 'lever point' ? Link to comment Share on other sites More sharing options...

PeterF Posted September 4, 2014 Share If you are putting a 42t on the back then you really should look at putting a 34t on the front, maybe a 32t if you really ride a lot of very big hills. With a 30t in front I think that you will be spinning out often. Steven Knoetze (sk27) 1 Link to comment Share on other sites More sharing options...

Wolfie1 Posted September 4, 2014 Share I am running a 30t with 11-36 cassette, Spin out on 36 km/h But i seem to not do that often and when you do spin out, it's normally doing tar riding. Cheapest option to do a 1x10 setup and still have a granny of some sorts Link to comment Share on other sites More sharing options...
