Vanilla 1.1.10 is a product of Lussumo. More Information: Documentation, Community Support.
When I reach a certain speed on my plug racer, there is a strange feeling unlike I have ever felt (or tried to describe). I feel it through the right pedal, so the source could be anywhere from the crank to the free wheel hub really, it is a deep kind of rubbing vibrating feeling that you can hear a bit.
Unfortunately that is the best description I can provide.
It is not effecting riding, I don't think, but it is incredibly annoying so if anyone can decode what I have said it would be greatly appreciated.
can you flip flop to fixed? if it disappears, there's your problem.
How old is the bike? I have a similar thing on my bike, but I know that the BB needs replaced. Could be that?
Have you got mudguards on?
It's a few weeks old, noticed it before I put mudguards on - they simply add to the orchestra.
slint:can you flip flop to fixed? if it disappears, there's your problem.
I guess I should, at the very least it would rule it out
Hmm, probs not the BB then. Could be a slight rub from the back brake if you've got one. If it's speed dependent, it could be wind passing through something (ahem). I've had funny noises from reflectors etc before.
I've heard that these work quite well with sorting out noise coming from the bike.
*chortle*
Yeah, i hate any sort of vibration. It kinda screams that the bike isn't set up correctly. Just a pet hate of mine. :)
Can you replicate the noise by lifting the backwheel off the ground and spinning the cranks?
I am certain it is from the drivetrain if that's what it's called.
Grinding is another word to add to my vague list.
euan:Can you replicate the noise by lifting the backwheel off the ground and spinning the cranks?
Yes, removed my chain for a clean earlier and after reassembling it was still pissing me off
is the back wheel straight in the frame?
it seems to be, but I have been wrong before. I will flip the wheel round and see what it tells me fixed. If that doesn't work, you can all point out something obvious to me at the alleycat

It's probably due a free service/check soon anyway (six weeks/1000 , miles or so) so you should mention it when you take it in.

Not many people ride 24 miles every day in the winter.

True. It's still probably due a service though, especially if there's vibration and noise that can't be accounted for.
yeah if itys that new
Could be that your chain tension is too high, that'll give you a nice grinding / vibrating feeling at the high point in the chainring where the chain tightens up slightly... I know it shouldn't but most chainset/chainrings have a very minor high point at the very least.
that was my next suggestion
take everything unnecessary off your bike, turn it over to fixed, throw out the above unnecessary items and there you go! on a serious note, yes, high chain tension is a) very common on of the peg s/s bikes as they come out the box and b) does give you an odd grinding noise at higher speeds. you can either wait till your chain stretches in or pop into a bike shop and ask them to re tension it for you...
I'm putting a bet on chain tension/lubrication
euan:I'm putting a bet on sexual tension/Lack of lubrication
It's 99% likely to be that over tightened new chain feeling.
It's like once you get above a certain rpm then you get this kind of sub bass feeling in your leg and it vibrates the whole pedal in a real deep way. Like the Sub Club floor.
That's happened to me with new chains that I've had a bit too tight. It doesn't seem to happen as much with old chains even if you over tighten them although if you really tighten them then it does happen.
Aye so basically don't panic, just loosen your wheel slide it forward a few mm and tighten it again.
Ended up stopping off at cycle lane on the way home from work, guy in the shop said the exact same thing. It has helped a little...though there is still some amount of vibration.
I am gonna flip the wheel on Saturday for a ride up the canal somewhere, hopefully everything will be nice and smooth. Anyone interested?
how is your chanline?
I have actually only checked it drunk...I remember thinking it appeared to be pretty centered. So it is probably fucked, I'll check again 2moro.

How many chains could you see?
