Help : Surly chain tugs

How do these things work?

I'm trying to figure it out. The axle goes through the hole, but when you adjust the screw (turn it clockwise), all you can do is move the axle forwards - hardly useful as this loosens the chain tension?

Heeelp.

axle goes through hole. the screw is facing backwards and is pushing against the dropout. if you pedal hard, the chain tensioner should prevent the hubs moving forward in the dropouts, preventing the chain from going slack.

it won't fit the other way around, i've tried. It only fits my dropouts like in the above pic.

I have this on my single speed. the screw fits into a little screwhole on the drop outs (which are front facing) and pulls the chain in the opposite direction to the pull of the cranks. on a bike with rear facing dropouts i think you use the hole closest to the screw (without the washer) and it fits somehow into the dropout.. not really sure, but it works ok on my front facing dropouts. oh and the little crests are a bottle opener - handy

here are my dropouts - will it fit these? there aint a screwhole ...

shrug. The condor shop guy said they would fit a track frame. try fitting it without the washer in either of the holes, or failing that go to the single-speed guy in the condor shop, he'll tell you whether it works or not :)

it should fit like the above pic. it should be in this order: hub, axle, dropouts, chain tensioner, nut. the screw moves against the dropouts.

don't bother with the surly they're £25 and don't come in pair, brcklane bikes have pairs for a tenner,i got some .

yeahh but you dont need a pair!

right-turn screw pushes the axle FORWARD though ... left-hand turn does jackshit to the axle.

And the washer's only for using with a quick release, init?

I like my cheapo ones from hubjub (EAI), though I had to 'spread' the 'cup' bit by hammering closed adjustable wrench jaws into it (for my thick alu dropouts).

anything like this?

sorry for the blurry pic.

asm yeahh but you dont need a pair!

i do, aluminium dropouts...as mike said and i listen to the wise ones ;)

Why do you need a pair on alu dropouts? I've been using a single one for about 15,000 miles, including high-stress sprints and climbs, and never had issues (other than psychological ones).

lpg - does this help: http://www.63xc.com/rickc/tuggnuts.htm

oh ok... dont bother with surly then. Bringmemyfix - yeah i remember now the washer is for quickrelease dropouts, the skewers on my bike are wierd semi quick release that use a tool that fits into the bolt to loosen. theyre pretty good actually!

asm - are they those semi-secure ones ie. not pitlock, but you use a 5mm allen key where there's normally a lever? Still got those on my wife's bike.

lpg - sounds like you've got something pushing against the axle that should be pushing against the rear edge of your dropouts/trackends.

hey lpg they do work i had one on my condor (similar track ends) the screw should have a cross plate on the endwhich pushes on either side of the track end (top to bottom not left to right) if the screw is pushing the axle it's broken

I've got two of the MKS ones from hubjub. Cheaper and work and NJS wank and I know you don't need two but I don't care and blah allen key or bolt type..

hippy I've got two of the MKS ones from hubjub. Cheaper and work and NJS wank and I know you don't need two but I don't care and blah allen key or bolt type..

I was one of the first to order one from Will, but it was before the 'fat' version, so I had to send them back. Been using the chav version he sent me ever since. 63xc RIP.

chav version?

Those cheapskate EAI ones he sells. I'm not talking about an MKS version with a Burberry paintjob.

haha doh.. just what the Raleigh needed!

pitlock sounds familiar... i should really pay more attention when the nice man in the bike shop waves things in front of my face and says "here thes are good, i'll fit them at the same time. better than plain bolts". basically its a little tool with a screwthread and a bolt which fits into a bolt-shaped hole on one side of the skewers. to take off the wheel you slide it in then tighten it and it grips it fairly hard allowing you to undo them/do them up very tight. theyre nice so long as you dont lose the tool.

Those Surly ones work well (although they're expensive). You need to turn the screw the other way, but you say that doesn't do anything. It might be that you have the axle through the wrong hole. The Surly tug requires you to use one of the two holes depending on where in the dropout the axle is. Give that a bash and it might work.

...jesus! what a 'mare!

Can someone please point me in the right direction for chain tugs that will fit a Langster and also protect the flimsy alu dropouts that are starting to look ragged?
