Morning All
I've had a funny creak coming from the bike for a few days now and this morning I tracked it down to the cranks. Any ideas what would have caused it in the first place, or is it just general wear and tear?
Its a M770 9spd with an XTR bb that was fitted about 3 months ago.
I plan to remove, clean and re fit in the hope this cures the creak.
Cheers All
Having the same issue with my Sram GXP BB and Sram XO cranks... not got correct tools for job though so LBS shall be checking it out next week. BB's only 3 months old and creaking like a gate already!

Movement as in pedalling causing the creak or movement from fittings coming loose?
Guess it amounts to the same thing really.
I'd also remove the chainring bolts, clean them up and put a dab of something like Rocol on them to stop them drying out and seizing up. Chainring bolts are a common cause of creaks and are often over-looked.
My chainring bolts are seized atm so you ay well be onto something there Hadge.
I take it Rocol is similar to Loctite?
It's an anti-seize grease that withstands heat but basically it's to stop anything binding. I use it on all my chainring bolts and pedal threads for instance and they come undone very easily but not when they shouldn't. If your bolts are seized now I'd say that's your problem. Soak them with WD40 and then take them off. Give them a damn good clean and then apply the grease. I'm sure that will sort your creak out.
I tried the WD40 approach without any success so I've ordered some Plusgas Dismantling Lubricant which should do the job. I've ordered some new bolts too just to be on the safe side.
While I've got my ordering hat on wheres best to get the Rocol from and do I need a specifuic type?
I'm sorry but no idea where to get Rocol from. We used it at my old place and I put some in a small pot for "home use" lol. It's known as copper slip so try looking for that but there are other anti-seize greases available ok. It comes in huge tubs which you'll never ever use up and I've only got a small amount left or else I'd have sent some over in a film pot. If you get some be careful as it stains terrible. Try Amazon - type in copper grease - there's plenty on that site
just incase, lube your seat post, you wouldn't believe the noises that were coming from my bike as a result of this!
Ah i think I have some copper slip kicking about somewhere, I'll hunt that out tomorrow.
Cheers for help Hadge 🙂
For lubing your post is it just a thin coating of any old grease?
