Maladie Posted September 20, 2009 Report Share Posted September 20, 2009 I don't really see any benefit in running a chain loose.Make it as tight as you dare really, just beware it could snap at any time. Quote Link to comment Share on other sites More sharing options...
Warbs Posted September 20, 2009 Report Share Posted September 20, 2009 Just not too tight as it will kill your bearings in the hub and freewheel!!! 1 Quote Link to comment Share on other sites More sharing options...
PaRtZ Posted September 20, 2009 Report Share Posted September 20, 2009 Are you running front freewheel?As far as Im aware, all freewheels do something called floating (some are worse than others) Basically as you spin the cranks round it looks like the freewheel is wobbling but this also alters the chain tension as the cranks go round giving tight spots in some and loose spots in others.Find the freewheel tight spot and put the cranks in the position. Then do chain tension so that when you push the top of the chain down with a mediocre force, halfway along the chainstay, the chain deflects about say 10mm. This should be enough so as not to kill your bearings, but keeps engagement quite accurate. Remember to check chain tension with the loose spot on the freewheel (usually 180 degrees away from the tight spot)Slack chains mean that as well as the chain smashing into your chain stay every hop, drivetrain components can also skip. Tight chains mean that drivetrain components are highly stressed, in some cases wont turn, it can stress bearings in a bad way, stresses the chain... theres no benefits to doing either, you need to spend time setting up your bike before riding it [/hypocrite] Quote Link to comment Share on other sites More sharing options...
Guest itstroy08 Posted September 20, 2009 Report Share Posted September 20, 2009 my chain is slack, but not slack enuf to fall off, just push your chain to one side spin cranks, watch you fingers mind if you have a ffw, as i now have a bit of finger missing bloody ffw but if you can push it w/o it coming off, your sorted, not too tight to snap ans screw your bearings up( dm if sealed) and not too loose to kill you Quote Link to comment Share on other sites More sharing options...
