Chain on my wrongster

My chain keeps get slack on my fixed wrongster, I use chain tugs so what the hells going on is my chain stretching? two nights in a row i've had to readjust

your chain is made of metal right? Its not stretching.

my doller goes on incorrect setup. ignoring the tugs for a second, how tight are you doing up the track nuts and are you sure the wheel is straight when you do it up? I mean, reaaaaally sure.

1.they hub will move slightly no matter how tight the nuts are or how tight the tugs are.......and yeah chains stretch a lot.......depends on how you ride......and what kinda chain you have......the shittier the chain the more will it stretch.....and its langster so its not top end ,is it????

2.the cog and the chainring will never be co-centric. So there will be tighter points and slacker points.......the higher the end the components are the more co centric they are......and maybe when you have tensioned the chain you have done it at the tight point of they chain.......and didnt check at the slack end.......

or.......

no its made of good old elastic. The wheel is straight and I tighten it so that its tight enough without binding, and put some serious pressure on the track nuts when tightening. Is it a job for brixton cycles or am I just being really stupid i think the latter

Check yer chain ring bolts

bog standard langster chain, had a link removed before to accommodate the the tugs, an chain recommendations?

scoober your chain is made of metal right? Its not stretching.

hehe i wish it was that easy:-)......why the fukk do they sell the chain tool to check the STRETCH of the chain......hm.....must be a scam then........
and your frame is made out of metal so it will never brake because of the material fatigue......

ok. without getting into the semantics of whether 'stretch' is a good term for the elongation of a chain caused by bushing wear, Im still gonna go out on a limb and suggest that his chain didnt appreciably stretch twice in two nights.

to the op, check your dropouts. You said you cranked down on the nuts pretty hard? It may be that you caused some indentation in the dropouts and now the nuts slip back into that indentation when you put the wheel back in.

Geez, two Sheldon's in less than an hour.. and both about chains..

Cyclists often speak of chain "stretch", as if the side plates of an old chain were pulled out of shape by the repeated stresses of pedaling. This is not actually how chains elongate. The major cause of chain "stretch" is wearing away of the metal where the rivet rotates inside of the bushing (or the "bushing" part of the inside plate) as the chain links flex and straighten as the chain goes onto and off of the sprockets. If you take apart an old, worn out chain, you can easily see the little notches worn into the sides of the rivets by the inside edges of the bushings. With bushingless chains, the inside edge of the side plate hole that rubs against the rivet has a smooth radius instead of a sharp corner. This probably contributes to the greater durability of bushingless chains.

Use good track nuts and tighten properly. Anyone know what the stock nuts are like?
You can use the chaintugs to drag the wheel back to get nice tension but they are a backup not the primary means to hold your wheel. Get your nuts right first.

cheers guys, I'll see what more I can achieve

i regularly get my nuts off, clean them and give them a good seeing to, before a good, hard screwing back on.

No, it's just a phrase used to denote bushing wear.

Chains don't really stretch, the bushings/links wear out eventually so the chain will lengthen, but this will take a lot lot lot longer than two nights (perhaps 4 months if you ride 6 hours a day in bad weather/mud).

I often buff up my nuts to a high shine before going out.

hippy Get your nuts right first.

I live by this motto.

I like to gently massage my nuts whiles wrenching my extendable spanner. Then lube them up a manmade lubricant.
