help before i ghost ride it into traffic!!!!!!!!!!!!!!!

[rakas17]

i'm trying to get my hawk f24 up and running and its got a horrible creak when  putting pressure on while pedaling.  i put a new chain on it, same. i tightened every up , same. i changed the back wheel , same. i changed the chain wheel, it had gone.  i looked at my chain wheel that was on there and it had a little bur on every tooth so i thought it might be catching on the chain.  so i set it up on the lathe and cleaned it all up, put it back on, same

 its a dmr one and i supposse its for mountain bikes, does this mean i'm using the wrong chain, my chain is a kmc £5 jobby.  do i need the other (racing) size chain and would i need a new freewheel too.


 please help before i smash it all up in a fit of rage...

In my experience creaks like that are usually caused by the pedals.

[harris]

back the crank arms of then grease then re tighten.
stodgys 26" started doing this ,it was the arms being an arse
then back the pedals of and try again then re tighten

[rakas17]

but it didnt do it with the other cd!!!   does what i said about the chain size thing not make sense?

[harris]

is it inline correct ,turn upside down and look down from chain wheel to freewheel  see if its offset

[MartyC]

Like Dan said but also check to see if it's out of true, i.e. not flat as the chain will pull it across as it rotates, other than that I have no idea  .

[harris]

if that lot fails ,get your camera out before it goes into the traffic 

[rakas17]

its defo in line, i'm pretty sure its flat. anyway, its at work now and i'm at home so it'll have to wait.

the creak is your bones mate, nothing wrong with your bike

age is creaping up

[Webdawg]

had the same prob today, me cranks were noisy as fcook.


Gonna have to take her apart, grease n c wot happens

luckily my creak aint me bones

[rakas17]

the creak is your bones mate, nothing wrong with your bike

age is creaping up

my bones are pretty fvcked but nothing to do with age, i'm only 30. younger than you bunch of bmx perverts

[superbikedan]

your  30,   spring chicken    rite then back to looking at your bike

does seem like your crank,  have you tried good old wd40

[rakas17]

not yet but nobodys listenung to me....    i changed the sprocket and the creaking wasnt there. it wouldnt be an issue but the sprocket on it ys mt cnc'd customised one

[harris]

we are listening rakas ,i was just checking the obvious as the new disc might have been a tad thicker
so you might have just got away with it with the other disc.
check the crank arms arnt catching anywhere  ,also some discs are off center and you might have a tight spot.

[MartyC]

Also, you might want to try and put copper grease on all the touch points of the chainring such as the axle hole, fixing bolt hole.  Is there much movement around the axle hole at all or is it a sung fit on the axle?

[bodamus]

I have had a terrible creaking noise before on my old Hutch and was convinced it was the Crank but turned out it was actually the Pedals were to tight.

What size Chain are you using is it definately 1/2" X 1/8" or is it the narrower race size? Might be worth investing in a better Chain anyway?

As others have said the disc could be slightly off centre which will throw it all out of line.

Good luck and hope you sort it out.

right, i've put my 39 tooth xposure one on that was on my single speed mountain bike and its not creaking. so i'm gonna order a new one of those and do the cnc'ing again..   

 thanks for all your input fellas, luckily the bike never did get ghost ridden into the m25 traffic.
