I’ve had enough of my SRAM red groupset
And now the rear mech is playing the harp on my spokes….even tho the adjuster is at the limit.
So I’m wondering…will the Di2 still work if I kept my SRAM red crank…..or does it need to be full shimano?.
Thanks

Red 22? Chainring spacing is slightly different,may cause issues.

Cranksets are not Di2 specific. Any 10 speed crank will work fine on 11 speed. The difference is so small its not noticeable.

May cause a bit of rubbing on the big chain ring when on the smallest sprocket and small ring.
Use to run a SRAM quarq power rank on my di2 bike, which has the same chain ring spacing

Ahh……sounds like it will be best to go full shimmy

Thanks guys

You sure the hanger isn’t bent?

Try putting a washer between the mech hanger and the mech.
