Ultegra Di2 Rear Derailer - today I learned...
Today I learned that an Ultegra RD-6870-SS Short Cage Derailleur is firmware locked to not allow the configuration of an 11-32 cassette in the eTube software... So even though you can replace the jockey wheel cage with the GS version with a few turns of the wrench you can't program the darned thing correctly...
Grr...
Oh well, was a fun exercise in calculating chain length, swapping parts (the stupid screw that keeps the cage from rotating back too far would NOT budge on the new inner GS cage part - I had to dremel a slot in it to get enough torque on it to move it) and ultimately cursing the Gods in the heavens...!
Guess I'll just go order a RD-8050-GS and call it a day.
