    I can’t get the non-drive side crank off! The spindle is attached to the drive side so, once the bolts have been taken out, the non-drive side crank should just slide off shouldn’t it?

    Brute force? Am I missing something?

    Any help gratefully received 😀

    Is there a locking collar which is operated by an Allen Key on the non-drive side, perhaps. Have a check.

    Not really but thanks 😀

    The problem is simply taking the crank arm off. There’s nothing else in the shell that can be holding it in as far as I can see. It’s a different system from both race Face and Shimano though:roll:

    BTW if you look at that link it says 16mm alan key 😯 It says it on the printed version I’ve got. Think it means 10mm 😆 surely.

    Dont think so on this system. I thought you only needed one for Isis and square taper 😕

    I’m not much of a mechanic mind…

    For future reference what you apparently have to do is leave the 10mm bolt in place and undo the 8mm one inside it. The bolt should be self extracting apparently 😀

    Gonna give it a go and see if it works.

    Was just about to say self-extractor.

    Its a bit of a ball ache. You have to put more force in than you’d expect.

    I always double check to see if I’m doing it right coz it doesn’t seem to do much at 1st. I used a hammer to tap the allen key round to get it started. 😯

    I’m not having much luck here 😆 Can BB’s seize in the frame? I can’t get mine out at all. I’m defo turning it the right way – opposite to the little indicator arrows.

    I’ve put a little chain oil on to see if that loosens it any.

    Any other ideas guys?

    “The left arm has a one-key release system. No puller is required to remove, simply use 8mm hex wrench and turn crank bolt counter-clockwise.”

    Hah, yeah sorry – forgot to update and say thanks. Yep cranks came off easy. BB removal tool just needed some erm, persuasion with a hammer.

    All done now – buttery smooth. 1st fairly major repair done 😀

    Thanks for all your help guys 8)
