Mark W Posted October 26, 2010 Report Share Posted October 26, 2010 Easiest way is to get the longest spoke you can (I used to use 268mm spokes and they were about right), then using a hammer and vice bend the spoke just after the threaded section 90°. With your wheel in the frame put that end of the spoke through your bolt for your mech hanger (so it goes from inside the frame pointing out), then put a nipple on it to keep it in place. Then you just have to wrap the spoke anti-clockwise around the hub axle as tight as you can, then once you've got a couple of coils around the hub axle just use a pair of pliars to put a gentle 'S' shape in the spoke to get it to sit nicely on the middle of the chain. Put a little upward kink on the tip of it so it doesn't stick into the chain and you're good to go. As I said, that's the easiest way of going about doing it. There are other ways that are a bit nicer in the long-term, but if you're just starting with them that's probably the best way Quote Link to comment Share on other sites More sharing options...

Azarathal Posted October 26, 2010 Report Share Posted October 26, 2010 There have only been a few pictures / written guidelines posted before, I suggest someone needs to make a definitive guide? I've failed to make quite a few, to be honest though I was using 158mm spokes Quote Link to comment Share on other sites More sharing options...

Is it for your Inspired? If so, your mech hanger bolts onto your frame - the bolt it uses is hollow, so just run it through that. Quote Link to comment Share on other sites More sharing options...
alex-trials-boy Posted October 26, 2010 Author Report Share Posted October 26, 2010 you i got yea i think so i bend the 90° put it through the bolt, screw a nipple in the end then wrap the spoke anticlockwise then make the small "s" and bend the end up? think im there lol ill go try it now longest spoke ive got is 260mm is that ok??

Mark W Posted October 26, 2010 Report Share Posted October 26, 2010 That's about right, yeah Spoke length depends on hub, sprocket size, etc. - mine were on either a Pro 2 T or a King (so quite a large axle to cover), and with larger sprockets which meant I needed more spoke. If you've got a 15t or under sprocket I would've thought it would be fine. Quote Link to comment Share on other sites More sharing options...
alex-trials-boy Posted October 26, 2010 Author Report Share Posted October 26, 2010 Well that failed say the spoke is 2mm thick the axle that is betweent the end of the frame and the end of the spacers was also 2mm the spoke rubed against the spacer when the bike moved forward and i made a rite hash of bending it in to sit nice on the chain Quote Link to comment Share on other sites More sharing options...
WIGAN ?? Posted October 26, 2010 Report Share Posted October 26, 2010 They are really tricky to make iv tried loads of times to get it right but just can't and I don't really trust them to be fair thers nothing really stopping the chain just bending off the spoke then your f**ked, I know people who run them and are confident with them will argue different but that's just me Quote Link to comment Share on other sites More sharing options...
alex-trials-boy Posted October 26, 2010 Author Report Share Posted October 26, 2010 you lol I've just gone back to using my sprung sensioner Quote Link to comment Share on other sites More sharing options...
Mark W Posted October 26, 2010 Report Share Posted October 26, 2010 thers nothing really stopping the chain just bending off the spoke then your f**ked, If you make it right, there's no reason it would do that? Your chain's going in a straight line, the spoke should be sitting in the little dip between the side plates - there's nothing to make it move sideways anywhere. Ran spoke tensioners for the past 9 months, haven't had it happen once... Quote Link to comment Share on other sites More sharing options...
dann2707 Posted October 26, 2010 Report Share Posted October 26, 2010 I've made one tonight, really really quick bodge. I used a mod spoke though, only managed to get it once around the axle bolt but seems to be okay-ish for now. Going to rob a 26" spoke from an unused bike outside tomorrow Quote Link to comment Share on other sites More sharing options...

I know what your saying but I think it's just a phycological thing that thers just that little bit of steel keeping my teeth in, I'd rather use a nice sturdy tensioner with jockey wheels Quote Link to comment Share on other sites More sharing options...
ogre Posted October 28, 2010 Report Share Posted October 28, 2010 usually your chain can't jump off anyway, unless it's mega slack, then a spoke tensioner probably isn't up the job, it doesn't take away masses of slack chain it just keeps a chain thats the right tension tighter Quote Link to comment Share on other sites More sharing options...
