Sponge Posted April 16, 2014 Report Share Posted April 16, 2014 Who knows how to make one of these from scratch? The photo below gives an idea of how it works, but even better would be if anybody has one and could explain how many & what small parts there are to it in all? - Where are good places to source the individual parts from? - What are the pros & cons of jockey wheels vs rollers? Bearings or bushings? It's just a tensioner at the end of the day, but it's a nice change to the usual and it'll be fun to make one. Something that runs quietly, smoothly and maintenance free would be ideal. Recommendations are appreciated! Thanks Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted April 16, 2014 Report Share Posted April 16, 2014 Personally I wouldn't bother - fixed tensioners are hit and miss at the best of times, even with two mounting positions. With just one it'll come loose all the time. Quote Link to comment Share on other sites More sharing options...
*gentlydoesit Posted April 16, 2014 Report Share Posted April 16, 2014 (edited) From the pic the only small part will be the collar and washers over the bearing bolt. What does the moveable arm anchor to? Edited April 16, 2014 by *gentlydoesit Quote Link to comment Share on other sites More sharing options...

Sponge Posted April 17, 2014 Author Report Share Posted April 17, 2014 Thanks for the heads up guys I had no idea they were like that! Are the Crewkerz Freed tensioners any good? The curvature of the mounting arm looks like it'd fit way better than other sprung tensioners with my hanger. I think it comes as it does in the pic below, so if I added an M10 bolt + a rubber washer + steel washer, would it mount like how the Trialtechs do?

forteh Posted April 17, 2014 Report Share Posted April 17, 2014 I made one from scratch, double jockey wheel, sprung, completely hidden and weighs nothing 5 Quote Link to comment Share on other sites More sharing options...

Al_Fel Posted April 18, 2014 Report Share Posted April 18, 2014 It's easy to see where your chain is joined! haha 1 Quote Link to comment Share on other sites More sharing options...
dan609fluid Posted April 21, 2014 Report Share Posted April 21, 2014 I have one of these on my leeson had loads of problem with other chain devices which always sliped. Fitted the k.i.s.s.s an never looked back. Its basicly a flat plate which bolts to the mech hanger using a nylock nut an blit. Other end is a bolt with a spacer and at roller bolted on. Realy simple. I will take a few pics Quote Link to comment Share on other sites More sharing options...
marshole82 Posted April 22, 2014 Report Share Posted April 22, 2014 I made one from scratch, double jockey wheel, sprung, completely hidden and weighs nothing i like this - how does it bolt up with the hub/frame? pic from above maybe?

bing Posted April 22, 2014 Report Share Posted April 22, 2014 It'll be heatsink/74kingz style, a right angled bracket that goes on the end of your axle Quote Link to comment Share on other sites More sharing options...
monkeyseemonkeydo Posted April 22, 2014 Report Share Posted April 22, 2014 It'll be heatsink/74kingz style, a right angled bracket that goes on the end of your axle You can see it's a 74Kingz style bracket but it's bolted to the hanger bolt rather than the axle.

bing Posted April 22, 2014 Report Share Posted April 22, 2014 You can see it's a 74Kingz style bracket but it's bolted to the hanger bolt rather than the axle. So it is, I've only just noticed. Very clever design Quote Link to comment Share on other sites More sharing options...
forteh Posted April 22, 2014 Report Share Posted April 22, 2014 Ask and ye shall receive! The chunk of aluminum angle is screwed through the mech hanger bolt and secured with a nylock, the height of the tensioner can be adjusted from here to allow for different chain length / ratio. Knocked up in my kitchen in an hour out so with hand tools Quote Link to comment Share on other sites More sharing options...
