  • Hi All,

    I'm considering running a higher capacity gearing than what the Ultegra R8050 DI2 Rear is spec'd for....

    Shimano says its max capacity is 37t and I want to run 41t

    Anyone had any experience? Am i just being stupid?

    Dunno about DI2 stuff, but I'm running my 32t capacity Sora rear on a 36t cassette which works fine, had to unscrew the b screw a few turns, but otherwise works flawless.
