London Fixed-gear and Single-speed SJS Cycles

Recently I've notice that there's a sporadic 'click' sound (feel through my feet to be precise) at every couple of rotation, usually when i'm trackstanding, defintely not the pedal as I temporary swapped them for clipless one (and almost fell over since I hasn't use them in years!).

could it be the frame being a bit flexy? as it's not a pure track frame to says the least, or perhaps I swapped the Miche Advanced chainring with a Campangolo one that's slighty thinner?

UPDATE: problem solve, a mere case of the crankset not being tighten enough to the BB, it was nowhere near the recommended torque.

I know this is going to sound strange, but check handlebar/stem interface.
mine used to click all the time on my BJ.
then check your chain, and see if any links are tight.
then check all the drivechain right down to the crankbolts.

oh and i've also found it can sometimes be the cog as it settles in.

Have you left a mouse in there?

I have one crankbolts that are not tight but can't be removed due to the shitty metal get chipped when trying to loosen it.

BB might need regreasing

could be the pedals

check your headset as well

I thought you said it was track specific :)

Your tyres are on backwards,

ah piss off pifko, itll take at least 3 pages to fix that shit!

fail wording on my part, more track specific, not literally.

there's no click sound when I put the bike on the stand, spinning the crank doesn't seemed to make noise, only when I'm trackstanding or applying a bit of force when turning.

Are you sure it's not just the bike frame flexing a bit?

I had the same problem, probably BB

when you put your foot down the shell takes a lot of pressure

Dont think the frame would be noisy unless there was a crack in one of the tubes

Could well be, but it's not the frame making the noise.

Clicks 'n ticks are usually from non-moving parts, ie interfaces.

Saddle against post, post against frame, frame against clamp, etc, etc....

Me too, on my first conversion, took the BB out and replaced it, no click.

I'll check out the BB first thing in the morning, it's a Miche one, it should last a bit considering I never even touch the BB from the Bianchi for years and still fine.

Check the cups are nice and tight.

i'm still going to back the handlebars being the source of the sound.

Not the Titan stem..?

I can't hear it mate, I feel the click through my feet, not my hand, it's very obviously from the drivetrain.

Ok, I understand.
In that case I'd say BB, what type you have in there?
also double check they brazed the ST to the BB shell...

A Miche Primato BB for the Miche crankset, it's a sealed cartridge one, I'll check it in the morning properly when I pop round to the LBS, don't have the tools with me.

ahh, sometimes they don't lock in or something.
did you use Threadlock or locktight?

BLB installed it for me for free when i went to pick up the frame, so no idea thought.

I'll find out tomorrow netherless.

...?

Buy some decent crank bolts? They shouldn't be loose, and they definitely shouldn't chip while you try to loosen them.

Similar thing was happening to me, I took everything off and re greased and put back on nice and tight (except chainring bolts) but to no avail.

I then took out the chain ring bolts, cleaned them, greased them and put them back on real tight and my problem was solved.

actually what happen was that the original crank bolts was too wide for the campangolo chainring, so I end up getting a shorter one, I replaced them all with the shorter one unfortuantely one of them refuse to come out and need to be drilled to removed it, that why I couldn't replaced just the one asap.

The Miche bolts are defintely quite weak.

In the timeless words of adam savage of mythbusters, 'There's yer problem.'

I'm replacing a miche primato (utter crap) BB since mine clicks as well on every rotation. So I'm going for a Campagnolo Centaur BB.

funny, my BB - also a miche primato - also clicks under load (accelerating, climbing)

Mine doesn't click when I accelerate or climb, only when I spin (which is most of the time).

I'd say BB needs taking out, cleaning, re-greasing(bearings), re-tightening - nice and tight. Had the same problem a few months back, fine now

your bike is clearly fucked Ed.
throw it away and start again.

Bob Jackson?

yeah, that'll be the BB shell coming adrift because they don't bother brazing them in properly

Did you run over one of those people counters recently?

I had something like this and it turned out to be this master link in the chain. I noticed it happened once for every 2 rotations of the cranks, then i noticed that the master link in the chain came round once every 2 rotations of the cranks.

It was a stiff link

Lordy, i've got the same thing on my road bike after switching chainsets, used diff pedals/chain, regreased everything, but still to no avail. after taking bb out, i saw it's not threaded exactly square on drive side and shell needs facing.

I had this problem on my old MTB. Every time I put some good pressure on the pedals, the clicking/squeeking noise started.

If you're completely sure it's not the pedals, then maybe fixing that crankbolt and getting a good one will fix it? Thinking that crank might be just sliiiiightly loose, so it moves abit when pressure's applied and makes the noise.

But if the crank is loose, you either have a busted taper or a busted crank. Or mixing JIS with ISO. Either way, exchange the cheaper part for one that fits or is not broken (the BB)

Everyone stop posting, I've already sort it out, but thanks netherless.

tighten the crank, clicking disappear, ride smoother than melted butter on a baby's arse.

The crank is simply not tightened enough to the BB, I didn't notice it because it feel solid and stable, thank fuck for that as I carefully chosen the component specifically to ensure a smooth and reliable ride.

is your bike a pipebomb?

But i like posting in this thread, I can relate to crappy bbs and loose cranks..

Or it could be the logos not aligned up properly.. :)

Nonce alert

Haha!

surprisingly a friends bike "click" sounded like it came from near the BB, but it was actually the handlebar interface.
it just appeared to be coming from there... weird.

It might be your legs, chop them off and go to the body shop for some new ones.

except as ed reminded me, he doesn't actually hear it, rather feels it through the legs.
in which case, chances are its the miche BB, as though I never had a problem with mine, lots of people complain about them coming loose, and clicking.

But yeah, the handlebar click is a hidden menace that is slowly taking down bicycle riding from the inside...
sinister fucks, thats why I ride using my finger and the stem.

already been sorted, it's simply the crankset not being tighten enough to the BB.

Fixed again, the clicking noise was still there, but not so noticable when the cranks wasn't tightened.

it turn out that the Campangolo chainring on a Miche Advanced cranks wasn't entirely in-line with the chain, it was at less a little under a millmetre out and consquencey cause the clicking sound (I think, or the teeth shaped slighty different to the Miche).

swapped it back to the Miche Advanced chainring - perfection.
