Cycle Fan Posted February 2, 2010 Share Hi guys, I need some advice/help please. I recently bought a new frame and components but ever since the build, my chain keeps jumping when in the middle gears. Does it when I'm in small and big blade. Taken it back to LBS twice now. They've replaced the cables but keeps doing it. Any suggestions? Link to comment Share on other sites More sharing options...
Mojoman Posted February 2, 2010 Share Was the chain also replaced? Any sticky links? Link to comment Share on other sites More sharing options...
Captain Slow Posted February 2, 2010 Share It sounds like your chain needs some Ritalin! Link to comment Share on other sites More sharing options...
Cycle Fan Posted February 2, 2010 Share Was the chain also replaced? Any sticky links? Chain, cassette, FD, RD - all new. JUst bought a new crank & BB which needs to be fitted. Hoping that might sort it out. Link to comment Share on other sites More sharing options...
chuck Posted February 2, 2010 Share Crank and BB won't fix it as it cannot cause it. You do not mention new chain rings? Based on the list of new items this would be the most likely culprit/s Link to comment Share on other sites More sharing options...
techguy Posted February 2, 2010 Share stiff link in the chain, pedal backwards and when the RD "blips" you've found the stiff link, then twist the chain along its length to loosen it... www.parktool.com has photos Link to comment Share on other sites More sharing options...
Cycle Fan Posted February 2, 2010 Share Thanks guys. Chainrings aren't new (but will be with then crankset). I'll ask my LBS to look at the stiff link. Thanks for the help! Link to comment Share on other sites More sharing options...
Tankman Posted February 2, 2010 Share try this! rear derailleur barrel needs to be adjusted... turn 1/8 at a time, then pedal and shift through the gears till you find the sweet spot. did the trick when i had the same issue. cable tension needs to be fine tuned after a couple of rides with new equipment or cables.
