was doing a bit of chain maintenance last night, took my front sprocket cover off to clear out all the gunk! noticed that there was wear on the top of my links, as if they had been rubbing against something enough to be worn down?

Anyone got any ideas? chain is at correct tention and was adjusted propely to spec at the weekend. I couldnt see/think of anything that it might have been rubbing against.

Trying to put a photo on but its taking ages to email to my comp - hopefully get it up at lunch

Thanks,

Matt

If the chain was run loose before it was adjusted it may have been rubbing against the stand (usually the mainstand , if you have one ) .

check along the chain path top and bottom, looking for any grooves where the chain has been rubbing

Could it be gunk inside the sprocket cover if it was sandy?

The lads are right Matthew, it has to be rubbing on something unless you have an attack of the "file fairies"!

Is you rear wheel in alignment ?

was aligned with verniers, then re checked with a steel rule after tightening, had the sprocket cover off and it was filthy inside - gonna take a proper look at the weekend - will keep yous posted.

that file faireys are a pain in the arse, they made my numberplate really small one night....

Guess what? Instead of just oiling my chain, I've removed it to give a good clean and have the same fairies! Tension has been within tolerances since putting the chain on new earlier this year following a break and can't see anything to explain it! Given the guard a good clean - only thing I can think of where its been rubbing. Around front sprocket was oily but no real dirt and no signs of damage on inside of cover.

Did you ever find your fairy?
