Another slack chain question

Are you doing the nut up tight enough?

Right, im a little confused....

The chain slackens off as the video shows after 30 mile rides. I am happy to get chain tugs fitted if this would sort the problem out? Maybe a trip to BLB would be best.

Im tightening the nut up as much as possible, ill tension the chain (tighten with wrench) and go for a ride later today and see if its any better

Turn the bike upside down and stand over the cranks looking down the length of the rear wheel. Do up the right hand nut (tight-ish) and leave the left-hand nut loose. Now push the wheel to the left and tighten the nut on the left. Loosen the nut on the right and push the wheel to the right. Tighten the right-hand nut. Loosen the left-hand nut and push the wheel to the left. Tighten the left-hand nut... Repeat until you've got the required tension.

i didnt use tugs for a while and kept getting slack. im guessing this is from doing hops fairly frequently. chain tugs solved all this.

i also do the sit behind the bike with feet on the pedals, and use one hand to pull the wheel and the other to tighten the nut.

You only need one on the drive side.

If you don't want a tug job (hehe), then be prepared to experiment further with more expensive (eg. Dura-Ace) track nuts, and/or scrape the paint off your track ends.

I'll have to check which track nuts i have, but at a guess they'd be dura ace as the wheelset is.
I got the chain taught (not over) as it should be and tightened both nuts up with wrench.

Chain has slackened slighly after spending a lot of time leg braking over a 5 mile ride... so i guess chain tugs would be the way forward.

Any advice regards a good setup for these? i have searched but there doesnt seem to be a definative answer

What width are your dropouts?

I have a pair of the MKS 'fat' tugs (http://www.hubjub.co.uk/mks/mks.htm) for £15 posted if you want.

Rolled up towel between the seat tube and the tyre while you tighten the nuts does the trick.

I've been using one of these things (I think they were free, but worth about 99p or something) on the drive side of my Condor since 2003. I think spending more than a fiver on tugs is fucking ridiculous, but some don't, so whatever.

chain tugs not only will help you get it tight at first but will also help you keep it tight continuously

Slack is better than too tight. Too tight wears your bearings and makes it a grind too ride. A bit slack rolls smoother and quieter.

Unbelievably, I only truly found this out within the past 4 days. My chain has been slightly slack....well loads more slack than I've ever had it before, and the result? A whisper quiet and honeyed ride. I really and truly can't believe the ride. Its so smooth, its better than any bike I've had from new. Even close to the hack I rode back in my courier days (a beater built up with a Campag and Miche parts...smooth and effective).

Why oh why have I followed the slack-is-bad mantra of this forum? I suppose too much slack is bad, but a bit of slack is like a night with the partner of your dreams. I will tighten it a bit, but never again the uber-taut chain from before.

As you were men (and graceful ladeez).

street baggers is the way to go.

murtle said so.

velocio has shares in bike component companies (and he owns the manufacturers of spoks and most tyres)

this whole forum is a scam to get us to misuse bike parts and wear out components, tyres and to lust after spoks

the "i dont like advertising" thing is a ruse

this whole website is about guerilla advertising

street baggers is the way to go.

it's** street slack**, or baggers

I think you'll find that if you had have followed the 'slack is not bad you muppets' mantra repeated by myself and RPM and and and instead of the wobbly trackstand-attempting hipster set you'd have been ok.

and me, chunks

Fair enough hippy and murtleflaps. I don't read most of this forum's stuff, as I'm sure you've gathered, but had I seen that advice, I would have tried it. Oh, who is this "RPM" you refer to, is he on this forum? ;)

Slack is better than too tight. Too tight wears your bearings and makes it a grind too ride. A bit slack rolls smoother and quieter.

Too slack, of course, means you get a quick demonstration of your minimum stopping distance, probably in rush hour traffic, as happened to me yesterday. Properly bent the chain too, so running slack didn't get much extra life out of that one.

chian noisy cause it needs oil.

clean all mating surfaces and tighten the bolts up more.

mating

hehe

Hi there, firstly the chain doesn't actually stretch, it wears out.

It strecht. Try puting a new and used one in parallel.

the link plates themselves do not stretch. the holes and pins wear, causing the chain to get longer.

i'm not too sure about that, i have had two chains, one new, one old, identical. count the links and even push the old ones links together, it will still be longer.
so i think the plates stretch too

Interesting. I've long seen the argument on this forum, that chains do not stretch. Not being the engineering type, I didn't want to get involved with that argument. But there is a lot of credence to what one sees with one's own eyes. Mirages are rare, and hallucinations don't occur that often either, and my eyes have said that chains stretch, though I have respected and believed the "doesn't stretch" comments on here.

Any mechanical engineers in da house?
