Kieran Morrison Posted November 2, 2010 Report Share Posted November 2, 2010 Hey, i have this really loud rub coming from posibly my cranks, its really more of a big screech, sounds like a sharp stone rubbing down a wall or something. What could it be? Possibly a stone in my freewheel? Quote Link to comment Share on other sites More sharing options...
trials owns Posted November 2, 2010 Report Share Posted November 2, 2010 worn cranks? do they wobble? Quote Link to comment Share on other sites More sharing options...
Kieran Morrison Posted November 2, 2010 Author Report Share Posted November 2, 2010 (edited) worn cranks? do they wobble? Nope, they don't wobble. The cranks are pretty* new. *tbc But in all seriousness they are quite new. I think it was a stone in them as the rubbing has almost stopped, and there are little broken up bits of gravel on my carpet. Also theres a big line going around my rim, so i also think that the bits beside where the pad goes on the cylinder (the 4 pointy things on each side) were hitting the rim as the pads were reeeeally close to the rim and they wore down alot.

It's this. New pad time, or at least re adjust the offending slave Quote Link to comment Share on other sites More sharing options...

t33zr Posted November 3, 2010 Report Share Posted November 3, 2010 (edited) Normal places to squeek.. 1. Cranks (between bb and cranks). Pull of cranks and grease on the bb where the cranks are mounted. Tighten good. They dont need to be broken or wobble to make noise. 2. Handle bar. Take the handlebar off, and lube the place where the handlebar clamps are. Some other places to check... Headset Freewheel Bottom bracket On these places you can normaly feel where its coming from.

LukasMcNeal Posted November 3, 2010 Report Share Posted November 3, 2010 You are aware how a freewheel works right? If there was a stone,rock or gravel etc in there you would known by now! Quote Link to comment Share on other sites More sharing options...
Kieran Morrison Posted November 3, 2010 Author Report Share Posted November 3, 2010 You are aware how a freewheel works right? If there was a stone,rock or gravel etc in there you would known by now! Oh sorry, i just thought it was possible that the gap between the bit with threads on it and the bit with the teeth on it could have a tiny bit of gravel in it causing it to scrape around both parts of the freewheel. Hopefully One of the suggestions that someone wrote will fix this. New pads should also be a win. Actualy now to think of it, i failed a sidehop the other night and hit my chainstays, possibly hitting my cams causing them to move (the space between the teeth is big as the teeth were cut into it) so maybe the snail cam bolt is inbetween the teeth? causing to make the wheel move over ever time i put pressure on the pedal? If not, it has to be the bb or freewheel. But with the scrape around the rim its also something to do with the pointy bits on the cylinder. Thanks to everybody who helped!
