Chain: Tight-Loose-Tight...

fuck. my friend is riding around on a fixed gear with one of those biopace rings... been meaning to swap it for him! thankfully he doesn't ride that often. the slacker.

Just tried Sheldoning it, and it's a bit better, but I'm gonna keep playing.

Pip, it's the difference between being very tigh (just how I like it) and looser, not crazy loose, but it's just annoying, and noisy.

And Dog's, no Biopace is shit!

TA rings are pretty shit. I've got one on my bike and it's pretty hard to get perfect chain tension.

I thought it was an Ok ring! :(

Has yours always done this?

Yup. It's not awful by any means...just a little (read a lot) annoying not being able to keep the chain tension the same throughout the crank rotation. At its slackest it isn't dangerously (or embarrassingly) droopy. You get what you pay for I guess. TA rings aren't bad but they're just not as good as Sugino/DA.

Damn my shallow wallet! :(

i get ya Dunc. if you can't see any distortion in the ring it self maybe it's a combination of chain ring, tight spot in the chain and rear cog

Looks like you got a fun evening testing man. process of elimination it is

did you make a sacrificial offering to tynan? said the magic words? etc etc

Tynan demands payment upfront. Until then your bike will slowly degrade into a Unipak

Does he take Solo or Electron?

Ye mockers shall feel the lick of my flame.

Anyone think it's worth going to Condor and getting another ring? This may just be a dodgy one!?

put the old one back on

they are known to be shite!

Tried that Hippy, kinda worked but not completely! And I ain't no noob!

Donut:

raises hand

explain the prob to them when you're there, they will tut, shake their heads and sell you something rahter expensive, chuckling as you solemnly leave the shop.

Thats no good!

option 2 is that you just ride it and ... well, stop complaining! hahaha! :D

Only noobs say they're not noobs.

Noob.

Racist.

either....
A. take it back.
B. put the old one back on (it looked much better)
c. stop digging yourself a hole in this thread before it turns into edscoble trying tp put a tyre on!..;)

You will never get it perfect. Get over it and ride!

Thanks all!

it will wear down eventually

BioPace is fine... I have a bike with BioPace on it and it's quite a nice ride... It is geared though.

maybe the cog on the rear isnot really round either, you can try putting the wheel in another position and try it again?

and you might want to move your chainring around a bolt or two

and pat your head and rub your tummy, whilst putting your left leg in and your right leg out..

put the old chainring back on.
