Is there any simple way of using an 11-32 cassette on a 7970 Di2 system?

    *7970. No such thing as 7870.

    And no, probably not.

    How low a gear do you need? Are you already running a compact chainset?

    32 spocket???? Man up and develop some thighs, or buy a hybrid. :D

    Yeah sorry, I meant 7970.
    I need it for a "100%" climb on my route, and don't say change the route, bike etc. - ok, I'll change both.

  • I was looking into this & apparently several people have made a 32 fit (depending upon hanger & bike geo apparently).

    I'm trying a 30 and hunting down a 33 ring for the front. But then I'm going to be climbing Alpe D'Huez 6 times in a row so i need some contingency for the latter climbs.
