Anything I need to know, having a few chain skipping moments and I think it’s down to having a bit of dried grass stuck around the bolts. Is it a torx key or Allen key to undo the bolts. ?

Torx……………………….you can do it with an Allen key but it takes ages and alot of swearing and you won’t be able to retention them after wards 😆

Torx if they’re the bolts that came with the cranks. Surely you can just firk the grass out with a small screwdriver?

if you can get the grass out without removing the rings then i would if i where you. getting them undone can be a PITA but getting them tight again without the proper tool to hold the back of the ring bolt can be even worse.

Torx – and I think Shimano use a mile long bar to tighten them up at the factory too 👿 best get a piece of wire or screw driver to clean them out if you can

cheers guys, think i might try getting it out with a small screwdriver first, its pretty well stuck in there, can see it taking some time….

Torx 30…..do not use a T25 as it will strip them.

managed to get it all out….. with an old knife and fork of all things!
