FINDUS Posted December 28, 2009 Report Share Posted December 28, 2009 Not sure why you would use a spanner But to use the mech as a chain tensioner you need some gear cable.you need one end to still have the nipple on and the other you thread through the mech as circled in my lovely picturethen bolt up and off you go!!!

Mark W Posted December 31, 2009 Report Share Posted December 31, 2009 Just as a side note, make sure you're still getting decent chain wrap around your rear sprocket! In that picture, it's kinda borderline, but if you had less than that you're starting to run the risk of the chain skipping more, or just simply putting more pressure on the chain by having less teeth on the sprocket engaging with it. If you can get your chain to go above the first jockey wheel of your mech then that'd be ideal. Quote Link to comment Share on other sites More sharing options...
