Make steep climbing that little bit easier.

By: on 19 November 2020
I don't have the legs to climb the steeper bits with the standard 11/28 cluster. The 11/32 has certainly made things easier and I have not found it too detrimental on the flat given that there are bigger gaps between most of the gears. If you're still building your "tree trunk" legs and need to get up the steep bits then this definitely helps. Slots straight in in place of the 11/28. I did have to adjust the DI2 a couple of touches and then perfection.
