KEEPitSTUPID Posted May 22, 2011 Report Share Posted May 22, 2011 Is this as simple as its the wrong chain? I was out on my XC just started a trail and boom, the chain went, luckily i could get to a road and coasted to the onsite bike shop, and bought an sram 9 speed chain, i fitted and got on with the trail, but the small set was unusable over anything slightly rough. Im useless with setting gears, im just learning all the setting up now as ive never had a bike with more than one front crank before, Quote Link to comment Share on other sites More sharing options...
trialsmax04 Posted May 22, 2011 Report Share Posted May 22, 2011 Remove the extra links to make it the sane size as the old one? New chains come longer than needed... Quote Link to comment Share on other sites More sharing options...
KEEPitSTUPID Posted May 22, 2011 Author Report Share Posted May 22, 2011 Awwww no, dont say ive made a school boy error, i shot the old chain in the bin and threw the other one on to get back on the trails, what an idiot, is there a way to work out how tight to have the chain? So i can work it out myself Quote Link to comment Share on other sites More sharing options...
davey1991 Posted May 22, 2011 Report Share Posted May 22, 2011 Get the chain so it holds the mech in the highest back gear without a cable. tada. Quote Link to comment Share on other sites More sharing options...
trialsmax04 Posted May 22, 2011 Report Share Posted May 22, 2011 Yes. Shift into the granny ring on the front, and the smallest gear on the back (i.e. 9th), then undo the power link connector and tighten the chain by overlapping the two pieces until the chain is tight enough to be ridden (should still taught, but the mech will still be swung back). Remove excess links from one side of the chain with a chain tool, then fix the chain with the power link. Finally check you havnt removed too much, by shifting into the biggest gear on the rear (1st) then biggest on the front (3rd). Mech shouldn't be any more than 45 degrees pointing forward.

So i can work it out myself Stick it on the 2 largest sprockets and shorten it until the rear mech is being pulled forwards at about 45°, this should give enough slack to still be able to change down, but not so much that it loses tension in the granny ring http://www.parktool.com/blog/repair-help/chain-length-sizing Quote Link to comment Share on other sites More sharing options...

Cap Posted May 22, 2011 Report Share Posted May 22, 2011 Not a case of worn cogs and new chain riding over them is it? Quote Link to comment Share on other sites More sharing options...
KEEPitSTUPID Posted May 28, 2011 Author Report Share Posted May 28, 2011 Not a case of worn cogs and new chain riding over them is it? Na theyre pretty good, you can see a sag in the top of the chain, ive ordered sum small splitters, ( through work haha) so will sort it and try and get that 45 degree angle that has been mentioned, and go from there Quote Link to comment Share on other sites More sharing options...
