My set up Di2 52-36 & 11-28. Using the di2 6870 short cage the max chain capcity is 33, exactly what my set up has.
I'd like to try the 11-32 without the cost of a new rear mech, the rear 32 with the front 36 should be fine but not with the front 52 which would increase the chain capcity to 37, and could cause damage/won't work as documented on many other threads.
Using the new 6870 firmware, I believe the syncro modes can be set to prevent 52:32 happening.
I am adding the bluetooth EW-101 di2 componant tomorrow, and will be able to test the scinerios using the existing 11-28 before I try swapping out for the 11-32.
Whilst I believe my logic is correct, is this idea flawed in any otherway?
