lightly grease the chainring bolt threads?

Tried it - made no difference.

mine makes alittle bit of noise but i think that it could be abit of chain stretch... whats your tension like?

I don't think it's chain stretch. The chain is only a couple of months old. Tension is spot on I reckon - 1/2" vertical play.

Try seeing if the chainring is bent vertically, or offset slightly in the spider bolts
i.e. it moves slightly up and down rather than side to side like you've already ruled out.

That would make your chain slightly tighter at a certain point in the pedal stroke, and cause such a noise, perhaps.
If it's that, there is an excellent article in Sheldon's about it but i can't for the life of me find it right now. It's in the fixed section, somewhere :)

Or alternatively it could be your cog on the rear with a similar problem.

I don't reckon it's vertical because when the bike is upside down, if you look down from above, i.e. in the plane of the chain ring, at the chain you can see the part of the chain on the bottom of the chain ring (nearest you) move out one way whilst the other part of the chain on the top (nearest the ground) move out the other way.

I'm pretty sure it's not the cog. EAI on Goldtec, and the chain and cog move round smoothly there, it's between the cog and chainring that you see the chain move laterally.

my reply

"I've watched the cranks go round, and I don't think it's them. I put a bit of blue tack between the chain stays and inside of the spider, and it doesn't move much. Perhaps 0.5 mm? Next to nothing; probably 0.5mm because of me moving rather than the cranks relative to the frame."

thats not even worth mentioning

I know... that's what's puzzling me... When it's all together, you can visibly see the chain move laterally.

Loose chainring bolt(s) ?

After you took the chainring off for inspection - did you put it back on to see if the problem was still there ?

Nope, not chain ring bolts. They were tight when I took it off for the first time. I put it back on yesterday evening, with light grease, and it made no difference.

This is so strange :S Thanks to all your replies so far.

Could possibly be a tight link in the chain? You haven't got a half link in there have you?

Nope. Bog standard SRAM 1/8" chain. I gave it a proper clean down and then went through every single link with a drop of lube, too. Made no difference at all.

both my bikes have slightly out of whack crank spiders..

one's noisy, one isn't.

I think these things are common with less expensive cranks and rings..

Yeah, it's weird. Slightly disappointing as I spent the extra £50 to get the Miche ones over the Sugino Mess RD thinking I wouldn't get any hassle like this. I just find it really weird it's suddenly started making more noise :-/

obivious but clicking cracking noise on down peddle could just require bit of re-greasing before putting back chainset-happened to me after lots of wet riding days?

Hmm, I don't think it's that because I can see that the chain moves side to side as the cranks rotate. I'll guess I'll find out tomorrow when/if I put them back on.

Yeah, I know :s I'm worried Condor are just going to fob me off. Don't have money for new cranks, either.

On Sunday I noticed my drivechain was making more noise than usual - almost a clicking at a particular point of each crank revolution.

Got back home, took chain off and spun the cranks hard whilst holding the seat tube and there's no vibration or noise. So definitely not the bb. No side to side wobble of the spindle, either. It's (Miche) only a couple of months old, not done too many miles, anyway.

Put it all back together, and with the bike upside down, when I spin the cranks you can see the chain move side to side as the cranks go round.

Take off the chainring, lay it flat, with the outside facing up, on a couple of surfaces and one side is raised by about 1-2mm - you can press it up and down.

Take it to Condor and they lay it facing down on a glass counter and say it's fine and to bring the cranks in.

I've watched the cranks go round, and I don't think it's them. I put a bit of blue tack between the chain stays and inside of the spider, and it doesn't move much. Perhaps 0.5 mm? Next to nothing; probably 0.5mm because of me moving rather than the cranks relative to the frame.

I was wondering what anyone else might think it is? I'm taking the cranks to condor tomorrow morning, but i don't see how they're going to test them - just wondered if any of you had any suggestions... takes me ages to get there on public transport plus I've got loads of uni work I'd rather be doing!

Edit: they're condor miche cranks.

Yep, it does.

Blimey, that's a bloody good deal on the pac... £160 is what I paid for my street scene large :O

It's often quite difficult to know what these kinds of ambiguously structured sentences are attempting to say.

Are you saying that the 'London trendy types' only ride fixed wheel or single speed bikes because these bikes are expensive ?

Bloody hell... my post made no sense whatsoever: writing lab reports for the last 8 hours until 1am clearly frazzled my brain. Perhaps I should proofread them one more time...

I think I was trying to say that ss/fixed is considered desirable by a reasonable number of people only in the cities. Outside of the cities, a massive Saracen full sus downhill with 38947 gears is desirable for the average Joe. They're needed for those massive kerbs. And there are more average Joes. I just can't see most people people buying a £99 singlespeed over a £99 full susser.

I'm going to stop typing; I'm getting no where :s

I can't believe it took 15 posts until someone mentioned Sheldon! :o

yeah so I wonder how fast you go on your Brompton, eh? ;)

haha :P I'm so glad that thing is gone :)

the trick is to be lane-assertive but go fast enough that you're not really slowing them down very much.

you can't cycle in the middle of the lane and be slow.

Yep. If you are slow, you just piss them off, then they try and overtake you when there's a traffic island in the middle of the road, and will end up knocking you off.

Sheldon reckoned its fine with a good quality skewer.....

He says it's fine for singlespeed. Fixed and brakeless? Hmm.

i'm not sure i agree with that. thinking like a driver is the only way to cycle, i think, in london: you gotta be aggressive, you have to be confident enough to sit in the middle of the lane and piss off all the cars behind you that can't squeeze by (and therefore knock you off) etc etc. if you cycle around like some pussy cyclist, always in the gutter, you are bound to get knocked off sooner or later.

I don't think I've made my point very well... It shows that I don't drive!

I agree with you about being aggressive and positioning yourself prominently. You'll never catch me doing it - pretty much my whole way to uni I ride in the middle of the lane, all the way along Hammersmith Road, Kensington High St and Kensington Gore. Riding in the gutter is a away to get yourself killed.

I think what I'm trying to say is a car driver doesn't have to think at traffic lights about pulling away quickly, or be overly worried if another driver might pull out on them when going past a junction on their left with a car turning onto your road, and so on. Overall I think a car driver has to be a lot less alert than a cyclist... A collision for them in London will probably be no more than a hefty nudge. For us it means serious injuries.

As I said, I don't drive, so I'm speculating what it's like for a driver.

Not an option with many banks at the mo, I applied about a week after the whole "test case" thing kicked off and all banks are now just sitting on the complaints until there told they have to pay. As they've appealed the decision it could be a while. Although they MUST act now if your in hardship (see the original linky above)

Ah right, didn't know that. Was over a year ago, maybe.

It amazes me how banks will get on their high horses when a customer goes a small amount overdrawn, yet they'll chuck students like myself with no collateral whatsoever and no full time employment a £1250 overdraft and a credit card :S

Ahh, I got the impression you had just bought your first fixed-wheel off some bloke, and were riding brakeless.

Asm and Tynan reckon it'd be ok with a tug/good quality QR skewer. Personally, I wouldn't just in case, and would have a look at the hub to see if it can be used with bolts.

Hmm, I can't see it catching on.

In my home town, Basingstoke, I think I can safely say I'm the only person riding singlespeed or fixed wheel. I hardly see another road cyclist, let alone ss/fixed! The town centre racks are full of cheap halfords bikes etc. These are the towns that have the £££ spare to just pop down Halfords (there are two bike shops in my town: Halfords, and Action Bikes!)

People look at it and are totally confused. Small children mock me (yep, "hahaha are you too poor for gears?!" from some little brat!). My mates think I'm bonkers. London is flat. Basingstoke, like the majority of the UK, isn't.

In London, where it's flat, and with the trendy-types. But then again, they've got the money, and if it wasn't expensive I'd doubt they'd do it.

Cynical? Maybe.

Actually, where can I get some Surly chain tugs?

This has got to be a wind up.

Try your library, if you don't want to buy them, but I highly recommend.

From what I've read regarding accidents, and from what you said, I'd say that it's probably your fault. I read a book called Cyclecraft* - can't remember the author - but he's an expert witness on cycle accidents. I reckon he'd say that you shouldn't of been filtering down the left hand side, and should have been in the primary position or centre of the road. Also, the driver should have looked before they turned. Both at fault.

+1 to what Momentum says about turning away. To avoid a collision: accelerate, brake, or turn sharply.

Glad to hear it wasn't serious.

*Yeah, yeah, I know, I know. Lot's of crap on how to put ride with one hand etc, but I highly recommend the advanced chapters. I don't drive, and even if I did, being a cyclist is totally different to being a driver in terms of how you behave.

Yeah, I really like wtp although I think if I were to get one the decals would be coming straight off. It's like an angsty teenager with a couple of photoshop has gone wild with dirty brushes.

Phoenix pro is out of my price range but i'm very tempted with the others...

Yeah, I'm after something for street, not race. the pk ripper looks awesome though :)

Do as Salmonchild says. Just go into your branch and be polite yet firm with them.

When I got stung for £60 for going overdrawn by a couple of quid, because of an unexpected direct debit when I was in between jobs, NatWest credited it back after just being polite and explaining the situation.

Condor might be able to get them for you. In the leaflets with my spesh shoes, which I bought at Condor, it says to just contact your dealer for replacement parts.

With some rim and tyre combinations it can just be a nightmare to get them on.

What I'd recommend is to put the wheel on a table. Stand facing side onto the wheel, with the side that the bead is stuck on facing towards you, positioned at 12 o clock. Place your palms on top and push down and then kind of roll it up and away from you. Use your body weight.

Good luck - don't give up!

I've got a 2HiP Death sitting under my bed not being used

Ahh man looks very nice from what I've seen on their web site. I'm not sure whether it's a good idea for my first proper dip into bmx to be a custom jobby I've put together.. I love building up bikes though :)

make me an offer I cannot refuse

The price on their web site is $300, so £150 brand new. What condition is it - used? Fork as well? What price you after? ;)
