Fixed broken again :(

[Joe24]

Well, only a few weeks after it was fixed, its now broken again Yes fixed is simple, and its ment to be hard wearing, but not my fixed!
At some traffic lights trackstanding, go to move off and my power goes, look down and my chain is off. Ok i thought, the chain has just jumped off(luckily it didnt catch) so i pulled over and got to puting the chain back on. I then notice a chainring bolt has come out
So, thats me done. I wasnt going to ride it home as it was so i got a lift back.
Called bike shop up and he says i need a new frame. The chain-line isnt exactly spot on, but its good enough, the crankset isnt the best, but its good for the money i ave, and the frame is abit old and flexy and not really ment to be run as fixed.
Ive sort of decided to get a new frame, and build up a proper fixed. The fixed now is abit of a bodge(as bad as it is to say) because its a 120 hub spaced up to 130.
The chainline cant be got any better because the cranks are over as far as they can go already, so they cant be got better.
Am i doing the right thing? I love riding fixed, but the problems with it now are just making it hard for me to see the fixed i have now as reliable.
Ive priced it all up, and its abou £280 as a quick look without shopping around too much. Ill give it a go building it up completely myself(probably with some help from dad if needed) and see how i go on.

is it worth you buying one of these and converting it?

Sorry, I know it's not the point, but I just can't work something out. You were track standing and the chain came off?

Fall off the table at school again JoJoe?

 

[Will1985]

Too much force again Joe?

Maybe these incidents are a way of telling you not to ride fixed...

 

[Joe24]

I moved off from traffic lights, slowly aswell.
Stop riding fixed, i dont think so.
This time it was due to the chainring bolt coming out, not me putting on too much power.
Bike hasnt been on a table since the first time i did it, well i did it again after but that was on the same day
Dave R, i could do, would just mean me putting in my back wheel from the fixed.
Possibility, but we dont buy from the internet so it wont work out as cheap if i bought that from a shop. Thanks for the suggestion though.

You don't buy from the internet? Wassat mean? (genuinely interested)

Well, what happens is i go to shops instead of clicking my mouse. My parents dont like it mainly, and i just dont do it, i go to shops instead.

Yes thanks I do understand the concept of not buying from the internet, I really meant why...but you knew that

My parents(well my dad) was born in a cave and thinks buying on the internet is bad and unsafe

 

[Radius]

Caves are all the rage you know.
Spose that's a good mentality in a way, I mean yeah you can save loads of money, and there's no evidence recurring enough to be viable that it's unsafe if you're careful, but you don't half (generally) get better support when you've bought from a shop. Plus you get to have whatever you're buying straight away

What frame and bits Joe?
My fixer is a 1949 frame and flexes like a spring, cheap wheels and chainset and it's lasted for years... I'm finding it hard to see where the problem is? More info required!

Its a 91 road frame, with system ex read hub, sunrace cranks with a strong(ish) chainring on.
I think the main problem is because the chainring cant get over far enough to get the chainline spot on.
It must be something for me to keep having problems with it though

OK, chainring needs to be further away from the frame?
Have you got the right width Bottom Bracket or could you get wider?
Use an old double or triple chainset (Bike Plus have triples for around £40) and swap the rings around. My fixed uses an old 52/42 chainring with the 42 where the 52 was. Even if the crank is too far out it may be easier to move the rear cog to meet it with spacers. Just a thougt. From your photo's the chainline does not seem that bad to cause the failiures photo'd.

Mal Volio and Fixedwheelnut on YACF are amongst the best and most experienced fixie brains around, could always ask them for some ideas.

I think i need to get over there.
Its less reliable then the Giant at the moment(but only because someone in the club sorted that out)
But what i dont get is how things seem to break or happen on it when really they shouldnt.
The chainring needs moving in abit in, but it cant. Not see spacers for sprockets though, so maybe this will help.
