Hi all, anyone know if it's possible to convert a short cage Ultegra di2 (6800) to take a larger than 28 tooth rear sprocket simply by changing the cage?
I'm suspecting the electronic head is the same on both derailleurs?
Thanks

    Ive read at least one person managing to run a 32 tooth rear on a short cage but wouldnt personally recommend it. The cages are the same on the regular mechs (i wrecked a di2 rear and bought a normal one as it was cheaper than all the parts). I did read that someone thought the parallelogram was different between them but i doubt it to be honest. Have a look here as it gives you the different part numbers and shows compatibility http://www.madison.co.uk/search?tags=rd ... t=&x=0&y=0

    It is possible to fit a larger cage - I think Ultegra do a medium cage version Di2 rear mech so the cage should be available as a spare - piece of cake to fit.
