RyanRs Posted April 23, 2005 Report Share Posted April 23, 2005 Help!! AAAARRG! For no apparent reason, my chain occasionally skips, like when it isn't in gear properly.. i have a KMC kwel chain, all links are good, the cog at the wheel isn't bent, the chain line from the rear cog to the chainring is almost a straight line, and my mech is setup in the right position to keep it on this gear (as i have taken all my other cogs off) if i turn the pedals anti clockwise, every 1 and half turns of the cranks, the chain jumps as it rolls onto the rear sprocket, like if one of the teeth are bent, but there ok! my chain is tensioned nicely too. Is it possible my KMC has worn out my rear cog? as they both aint exactly new! I no there are single speed cogs with longer teeth, should i get one of these? and where from? What is wrong with the bloody thing! its driving me insane as it completely takes my confidence away when going for a gap or even Pedaling fast!! HEELPPP!

Lawnmowerman Posted April 23, 2005 Report Share Posted April 23, 2005 your sprocket is worn, check the teeth to see if they are hook shaped >_< Quote Link to comment Share on other sites More sharing options...
Urpedigreechumdog Posted April 23, 2005 Report Share Posted April 23, 2005 (edited) You my friend, may have a stiff link >_< Find it and sort it :turned: Edited April 23, 2005 by Urpedigreechumdog Quote Link to comment Share on other sites More sharing options...
RyanRs Posted April 23, 2005 Author Report Share Posted April 23, 2005 You my friend, may have a stiff link >_< Find it and sort it :turned: ← nope, no stiff links. checked every one! expecially where it jumps. but the jumps on the rear cog seem random! i think trialsboy560 may be correct with the worn sprocket though?? -i hope it is something as simple as this!

N.Wood Posted April 23, 2005 Report Share Posted April 23, 2005 Could be: Chain, Mech, Mech hanger, chainring or sprocket. Pedel forwards, if it catches on the chainring, replace it as it's hooked. Your mech/hanger may be bent, check that. Check everything! Quote Link to comment Share on other sites More sharing options...

You will need a locked out mech or SS tensioner for it to work. I'm not sure how this wil sort your problem. Check everything in the vacinity as i have said above.

ZeroMatt Posted April 25, 2005 Report Share Posted April 25, 2005 Maybe you have the chain on upside down, because on one side there is a larger section removed, that side is meant to be down when looking onto the chainring apparently. Just a very rough guess and probably wrong. Matt Quote Link to comment Share on other sites More sharing options...
Davetrials Posted April 25, 2005 Report Share Posted April 25, 2005 your sprocket is worn, check the teeth to see if they are hook shaped (Y) ← One of the 1st things to check when you work ina bike shop. Quote Link to comment Share on other sites More sharing options...
RyanRs Posted April 25, 2005 Author Report Share Posted April 25, 2005 Thanx for the help everyone! Seems it may have been the rear cog being warn and the general straightness of the chain line, as i have replaced the rear cog and moved it up the freehub a bit to get a perfect chain line with the cranks. the problem seems to be fixed now!
