    Shimano Nexus SG-3C41: can coaster brake be removed?


    Can the coaster brake attachment (looks like a projecting arm) be removed without any negative effects? If not, can it be left unused?

    You cannot do it. Whenever you back pedal, the hub will also turn backwards and the brake will not work. This "projecting arm" also attaches in a specific place in the hub, so no possibility to assemble it somewhere else.

    The SG-3C41 (exploded parts diagram) has a roller-cam actuated coaster brake, copied from the old Fichtel&Sachs design. I have never done this with a Shimano hub and IT MIGHT BE DANGEROUS and/or destroy the hub: it might be possible to remove the six rollers from the Y-33R-90700 Carrier Unit and disable the coaster brake, and saw off the coaster brake arm (which, unlike the modern SRAM coaster hubs, is made as an integral part of the Y-35U 98050 Brake Arm Unit).

    Me? I'd sell it and buy an SG-3R40 non-coaster hub.

    I have done it on a 7 speed hub by removing the rollers and cuting the arm with a grinder.

    You can get some of those hubs dirt cheap, not a big "financial" risk.

    I must add : It was not feeling like a normal hub after the transplant , a bit clunky.
