DMR Chain Tugs Chain Tensioner is rated 4.4 out of 5 by 14.
Rated 4 out of 5 by bredamatos from Does the job Does what is announced. A bit tricky to mount, though. Had some difficulties with my 30 year old Orbita (Portuguese bike). In the end, it is securing the chain and I am happy with my single-speed, 30 year old bike.

Rated 4 out of 5 by PhilFromBahrain from Nice product but requires longer axles Well made and works fine but adds thickness to the axle housing which means ideally having a longer axle. Otherwise the wheel nuts are only half filled.

Rated 4 out of 5 by PJ2009 from does the job! I have bought two pairs of these after the original DMRs just got too corroded after years of wet muddy and salty conditions. These were better but on one particularly fast and bumpy ride I lost the adjuster nuts as they had come loose. However, they work well with the bike.

Hi Anyone used these on a Charge Plug or know if they fit the Charge Plug frame? Particularly the frame sized as 'small'. Many thanks in advance MG

Are these suitable for a 2008 Specialized Tricross Singlecross?

I ask because this bike has a steel reinforcing plate on each rear dropout and I have seen comments saying that some chain tugs will not fit over it TIA
Asked by: riposte
We believe this item will fit this bike but not totally sure as we do not sell this bike. If these are incorrect you will be able to return them under our returns policy but please keep the packaging and labels if you wish to do this. Please also note you will have to pay the return postage on this item or use the collect + service.

Sorry, could someone explain the difference in the size?

Is it the diameter of the hole? i have a single speed MTB and don't want to rode the wrong size.
Asked by: SmeeZee
Yes, diameter of the hole. The larger one is for a solid axle, the smaller is for Quick release.

This is really basic - do these things allow you to pull backwheels back symmetrically?

I have a commuter bike with Shimano NExus gears. Chain stretches and starts to jump. Can I use these to help me pull the wheel back hilst keeping it aligned - adn do they just fit while I use them or do they stay on all the time?
Asked by: RAJ47
Stay on all the time. I've got one fitted to an Alfine. Make sure you have the white "non-turn" washers as they will be compatible with this. The blue/green turn washers need to go into the slot on the dropout which will have the tensioner in it so won't fit. They will allow you to pull the wheel back symmetrically although you'll need align it yourself. I'm assuming your dropouts are slot dropouts. If they aren't this won't do any good.

Are these suitable for 3 speed hub geared bikes?

For example a Sturmey Archer or Sachs Huret 3 speed hub.

Hi Will this fit the new Charge Plug 1, the 2016 model? I'm guessing its's easier (lazier) to set tension with this? Thanks David

Suitable for a Reynolds 531C fixie conversion ?

Will these fit a 531C road frame with conventional forward-facing horizontal dropouts ? (i.e wheel opening at the front, not the rear-facing dropouts of a track frame )
Asked by: YouMustEnterANickname
Unfortunately this would not be suitable as they there is no resistance for them to work against.
