Do You Trust Spke Chain Tensioners


Matt Vandart

Recommended Posts

I made this spoke tensioner and was wondering if I got it right.

Luckily the frame had a couple o holes in the drop out which I could use as a reaction thingy.

It's held on at the back by a nipple.

It seems to tension the chain quite well but whats to stop the tensioner falling off the chain if you get me.

Here are some pics.

How long have you been using spoke tensioners?

Ever had any problems?

Surely they wear chains out quicker?

Quite a few months.

None at all.

Nope. In fact, the tensioner wears down because it's (relatively soft) stainless steel.

I wouldn't trust yours Matt unfortunately, it needs at least 2 coils to produce enough force to stay in the groove of the chain. Without any coils, the spoke just bends and tension falls away.

Not hard.

Bend a spoke just before the threads (threaded section in a vice, use a hammer).

Put that little handle into a hole in your frame.

Wrap it anti-clockwise around the spacer on your rear hub's axle.

Bend it in an S-shape at the end so it sits on the rollers of your chain.

Profit.

Any betterer?

I have some trust issues with mine after I saw it dipping it's little spokey hand into my wallet, but now we're pretty much on the level so although I do keep an eye on it, I'm reasonably trusting of it.

Pissing myself laughing

dude...you have to be able to take another link out of that chain. you should be attempting to have as little chain on your bike as in that picture mark posted earlier....on top of this you would get more of the spoke which wrapped around the hub, which sould mean more tension.

this is what you seem to be missing you little sausage

I know what your saying but it wont, or if I do it will be mega tight and the f**king stupid tyre will foul on the frame.

By the way, a chocolate teapot works beter than the tensioner I just made, lol.

By the time I have done this that 16t sproket will have got here knowing the Tart and his wee tartlets, working away like busy beavers packing and sending off shit to all the lucky boys and girls that have taken up this incredibly annoying sport.

f**k this I'm getting a new BMX...........

If you've got your old chain still put 5-6 old links in your new chain and that should give you enough length to wear in part of the new chain without the tyre hitting the frame. Then, when that's cool and the gang, replace the older links with newer ones. Winner.

Matt, try putting a bolt through one of those holes, and coil the spoke around it to create a spring. Like I have:

By having this you can take your rear wheel off as normal (incase of pinch flats, re-grinds, etc..) - instead of having your tensioner wrapped around the hub and it causeing problems :rolleyes:
