The older I get, the faster I used to be ...
Thanks - lots of useful information ......
- if you click through to 6800GS mech it states 32T compatible, and a number of brands are offering 32T cassette options on their bikes.The dropdown spec here however does say it would only accommodate a 28T large cog. A +6T push is quite a lot which imho would be impossible to predict without trying, but certainly not unprecedented.
