A while ago i was riding home after a days laning and from the back end of my bike i could just hear "KKKKKKKKKKKKKKKKKKKKKKKK"......i real "metal on metal" sound. when i got home i could grab the rear sprocket and move it about an inch! the sprocket carrier bearing had disintegrated!

Well......

on sat on was riding on home, and what did i hear coming from the back of the back...."KKKKKKKKKKKKKKKKKKK"!! the same ****in noise.

Its a rhythmic metal on metal sound, if you pull the clutch in the sound stops - so its only when its under drive.

When i grabbed the sprocket....no movement!
so i grabbed the back wheel.....no momement!
swing arm?....no movement!

i put her on the center stand and into first, gave her some throttle.....no noise. i did notice how unbalanced my Army special tyre is though and the rear sprocket had a very slight fluctuation.

i dropped the revs down, put her into second gear and opened her up....."KKKKKKKKKKKKK" coming from the back wheel area. (also nearly fell off the center stand!)

Just very quickly dropped the wheel out....all looks fine? i know my cush drive is ****ed so am ordering a new one from Wemoto. i know my chain is ****ed and will be getting one soon-ish (i don't want to put a new chain on in the winter )

More investigation needed....any thoughts?

Thanks
