    Question on 1x11 swap

    I have a gt sensor elite am thinking about going to a 1x11 set up. Here's my question... stock is the fc-m612 crank set... I'm looking at going with the xt fc-m8000-1 crank set. Does anyone know offhand if my current bottom bracket will work out is the only way to know too try?

    Both are 24mm hollowtech cranks, so should work fine with the same bb. You should be able to convert the fc-m612 to 1x though by removing the inner and outer chainrings and replacing the center one with a narrow-wide ring, so no need to replace the whole thing.

    Definitely try your existing cranks first. Sometimes the 2x and 3x cranks can give a nicer chainline anyway, it depends on your specific bike. Plus you can often play with the spacers/washers either side of the BB - technically it throws the cranks a little off-centre, but you'd struggle to notice in practice.

    I converted my 3x by removing the small ring, replacing the middle ring with a narrow wide, and replacing the big ring with a bash ring, that kept the chainline right in the center where it needed to be.

    Yeah, if you have a triple crank, just take off the 3 old rings and put a narrow/wider ring in the middle ring position. Easy!
