rider_01 Posted October 21, 2007 Report Share Posted October 21, 2007 I made one the other day, It's all titanium even the nuts,bolts and washers are . The jockey wheel's carbon fibreI could probably do with taking a link out of my chain now.in favour of jim i have to say that the tensioner is the bizz works a treat and also looks the part i had a go of his bike and there is no chain slack what so ever top job jim sean Quote Link to comment Share on other sites More sharing options...

Krisboats Posted October 21, 2007 Report Share Posted October 21, 2007 Be honest with you...I think it looks better than people's who have done same as Bigman. I think that looks tacky and weak to be honest.Have you seen mine up close yet? They may look weak but you can smash them into things all day long and nothing happens to them, the chain won't even come off the cog.Yet with my mech it was an unnecessarily heavy block of metal that was attached to something that kept bending. Which meant i'd have to get off the bike and bend it back before continuing, rather than just carrying on like nohing had happened. Its not like their difficult or expensive to make, and they make the bike look neater with less stuff to worry about. Quote Link to comment Share on other sites More sharing options...
Bigman Posted October 21, 2007 Report Share Posted October 21, 2007 Haha, i know my tensioner may look weak, but i have hit that sooooo many times and it just keeps bouncing back, it would outlast a mech on a trials bike easily, i look at all these ones that people are making now and i have to say they are ok, but the way you mount the sprocket is quite important, like the one above with the carbon cog, having a big C shapped bracket is just begging to be broken, if you can make it so that the bolt that the cog bolts to go straight onto the spring steel it is alot better! (That is what mine is like, it has a small block of alu with a hole for the bolt for the sprocket, i can get pics for people if they want them).Adam Quote Link to comment Share on other sites More sharing options...

I like that Ti one but it would be much neater if you could tension up instead of down. Quote Link to comment Share on other sites More sharing options...

I like that Ti one but it would be much neater if you could tension up instead of down.It is not actualy that simple as you have to make sure that the sprocket is central on the spring steel, as otherwise if it is not the steel will twist, on mine the spring steel is around 1n inch across where the bolt fix's it to the L bracket, but where the sprocket is bolted it is only 10mm ish, so that the sprocket sits inline with where the bolt holds it onto the L bracket, if you can understand what i am saying....Adam Quote Link to comment Share on other sites More sharing options...

I'l see how it goes when I alter my gearing. Your right about the Ti not breaking. It's seriously tough stuff. I could have made it out of thicker gauge but I really didnt need to.

Im making a mahogony and jubilee clip tensioner similar to the steel one I have now. Quote Link to comment Share on other sites More sharing options...

Ben Beckett Posted October 24, 2007 Report Share Posted October 24, 2007 made one at work yesturday cuz my chain snapped on sunday in brizzol, and done a sidehop- made it on top of wall but not good positioning so i jumped off bike and my foot got caught behind wheel and bike hit floor bending mech hanger, so made this Quote Link to comment Share on other sites More sharing options...
2sixstreet Posted October 24, 2007 Report Share Posted October 24, 2007 Hangs too far down for my liking but top effort all the same. At least get rid of the mech hanger now. Quote Link to comment Share on other sites More sharing options...

Dan_Trials Posted October 24, 2007 Report Share Posted October 24, 2007 its gay man, i had to put 2 more links in for it to go round bash Put it on from the bottom bracket side of the chainring rather than the bash guard side. Quote Link to comment Share on other sites More sharing options...
JonMack Posted October 24, 2007 Report Share Posted October 24, 2007 (edited) Put it on from the bottom bracket side of the chainring rather than the bash guard side.Exactly. Put the chain onto the bike, then pull it onto the chainring then pedal the chain through, don't start from the other side!

toyota200x Posted December 1, 2007 Report Share Posted December 1, 2007 Has anyone built any new tensioners? I love this thread and I would hate to see it die. Quote Link to comment Share on other sites More sharing options...
gathsano Posted December 1, 2007 Report Share Posted December 1, 2007 Here's my attempt. I beat up my 74 Kings tensioner on a wall (what's new) so decided to hammer out the part that attaches to the drop out and bolt an old jockey wheel salvaged from a DMR tensioner. I took of a spring loaded,jockey wheel type recently due to it slippin all the time, this super bodge hasn't slipped once plus it cost me nothing. Bargain.

matt rushton Posted December 8, 2007 Report Share Posted December 8, 2007 Heres myne, took 5 minutes to make, 5 minutes to put on. Its just basically a piece of metal with 3 holes, a jockey wheel, and a spring. Quote Link to comment Share on other sites More sharing options...
2sixstreet Posted December 8, 2007 Report Share Posted December 8, 2007 My latest version has been on a serious diet. Rotates around the hub and tensions by the spring attached to the seat tube. Been running for over a month with no problems. The arm is spring steel so if it bends you can just bend it back. It has a small amount of side float too so it follows the chain line if it shifts.

Luke Rainbird Posted December 8, 2007 Report Share Posted December 8, 2007 It's not bad, Dave, but we need to work out a way to eliminate that spring somehow (well, to get it off the seatstay really)Streamlining is the way forward...

I'm open to suggestions. The way I see it the spring is necessary unless I go back back to the B-tension type arrangement. Quote Link to comment Share on other sites More sharing options...

Just a little messy to do that to something so pretty!It's like shitting on Keira Knightley's face Quote Link to comment Share on other sites More sharing options...
