You mentioned changing to a different change width? Also, any changes to the BB required?
Here's a pic of me and this bike.
Thanks!
I am not sure I follow. With your standard (double) crank, you can easily go to a 29 with the medium cage derailleur. You can switch to a compact crank and still reach the 29. I have a short with a 50x34 13x26 with no problem. I think the only time you need the long cage is when you are using a triple with the 29.
I did not switch my BB when I went from standard to compact.
I am not sure about the chain length. I would put the new crank on and see if you can remove 2 links or not.
