roozor Posted February 17, 2005 Report Share Posted February 17, 2005 I dont have the cash for a dmr single speed chain device thing, but on my zebdi, cant i use my rear mech and lock it out so it's stiff and use that to get extra tightness in the chain? I wanted to lock it up and cable tie it to my frame. If so how?, i heard you have to take out the springs. Alex Quote Link to comment Share on other sites More sharing options...

tipsy Jock Posted February 17, 2005 Report Share Posted February 17, 2005 Theres another way. instead of faffing around with springs and circlips just remove the spring and circlip, put a magura evo mount washer in its place and tighten until it locks up :) Pete Quote Link to comment Share on other sites More sharing options...

If you have any old velcro watch straps lying round use that instead of a zip tie so you dont have to cut off the zip tie everytime you need to take the wheel out...

rich4130 Posted February 17, 2005 Report Share Posted February 17, 2005 extra tightness in the chain? ← You'll not get any extra tightness, it will just stop it banging. You need to shorten your chain to do that. Quote Link to comment Share on other sites More sharing options...

Mark W Posted February 17, 2005 Report Share Posted February 17, 2005 If you want it so it takes up some chain slack, there is another way... Break the chain and take it out of the mech. Then, thread it through so it goes UNDERNEATH the top jockey wheel, whereas before it went over it. You can then run it straight from that jockey wheel to the chainring, so it'll mean that because of the natural movement of the derailleur it'll keep pulling the chain tight. You can then cut down the excess (the bottom half) of the mech and Bob's your uncle... Mark. Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted February 17, 2005 Report Share Posted February 17, 2005 One 'problem' with that is you dont get very much chain/sprocket contact, which wears everything out a fair bit faster. Quote Link to comment Share on other sites More sharing options...
Mark W Posted February 17, 2005 Report Share Posted February 17, 2005 Hadn't though of that, I see where you're coming from now. Because it gets pulled up quite near to the chainstay though, it might not be *so* bad? Either way, I'll check out how my friend's bodge like that is going and let y'all know. It basically ends up like being a Forge tensioner, but actually good :huh: Quote Link to comment Share on other sites More sharing options...
