Chain tension
« on: October 24, 2013, 06:02 PM »
Ok, a bit of a question that I should know the answer to.

I am having difficulty getting the chain tension right on my Haro, on my old burners I have the raleigh chain adjusters so its easy to get right. With the Haro I am putting my knuckles between the tyre and the bottom bracket to push the wheel back, lining it up straight and then tightening it. But when I tighten it, I find the wheel moves a touch and the chain seems slightly slack.

Whats the correct chain tension for a bmx? and is there a tried and tested technique for bikes with out chain adjusters?

I always have a few millimetres of slack, it puts less strain on the freewheel and hub. :daumenhoch:

Get some tensioners Steve probably move again when you ride it.

http://www.ebay.co.uk/itm/Conspiracy-BMX-Chain-Tensioners-Adjusters-Tugs-10mm-or-14mm-Incl-safety-end-nuts-/251272203655?pt=UK_sportsleisure_cycling_bikeparts_SR&var=&hash=item3a80fd8d87

Check out a half link better for small adjustments.

I think I have a new set of 10mm burner copy ones in the garage, I'll have a look,  that will pull the wheel back evenly
