  • So after eight faithful years service my etap 11 speed rear mech appears to have died.
    Assuming nothing miraculous happens and it suddenly comes to life, I have a decision to make about getting my good bike back on the road.
    I want fully wireless shifting as the frame is old and has no internal routing for wires, so does that mean I’m looking at Sram again? Or is shimano on the table?
    It’s a rim brake frame and I have brake callipers and a power meter chainset, so I don’t need a full groupset.
    Also, I’d prefer to stay 11 speed if I can as I have another bike running 11 speed and have various chains and cassettes that are all 11 speed, but if I have to move to 12 speed then I’ll suck it up.
    I’m completely out of touch with groupsets so any advice would be appreciated.

  • Shimano Di2 12-speed is what they term a semi-wireless groupset. Basically the shifters have their own battery each, then the front and rear derailleur is powered by a battery that they are attached to by wires. There is no compatibility between 11 and 12 speed.

    SRAM remains completely wireless, but is also 12 speed. You might be able to pick up an 11 speed groupset, but they are becoming increasingly harder to find.
