Creaky bottom bracket...

[Hebden]

Hi Guys,

I have a Camagnolo Ultra Torque Centaur crank set (about 1 year old) on my road bike. And when I stand and push hard on the crank side pedal I hear/feel a creak....creak...creak. It’s kind of annoying and I would like to get rid of it.

I was looking for some opinions on if I should try it myself and what I will need. I need some kind of bottom bracket tool that fits the 16 tooth ring on either side if the BB. And Do I need a toque wrench? Is that so I don't over/under tighten anything?

If I do it, what should I look for? What could be causing the creaking? Do I just grease it up and put it all back together again? Also what grease should I use?

Thanks heaps, in advance!
Mark

You sure it's the BB and not, for example, your handlebars? When you push down on the pedal you pull up on the handlebars.

Sadly creaks and noises can come from almost anything ... headset, bottom bracket, cranks, pedals, frame etc ... I've resigned to living with a similar type of creak for a while with my bike. Hoping one day I'll take some part off and re-install and the noise will go

Yeah I am pretty sure. I was suspecting the handle bras at first though. So I had my son get down next to the crank and I held the bike still and put some weight on the drive side pedal. He said its coming from inside the BB. And it creaks every time I push on it.

I wish it where the handle bars... I have an Allen key

Great link, thanks! I might get a second opinion on the source of the creak too.

i dont know if this is above board but i have solved creaking 'bottom bracket' issues with with a bit of marine grease on the rear quick release frame/clamp interface

Creaking bb, cranks, pedals will all sound like the noise is coming from the bb; since the latter two are easier to remove/install than the bb I'd be doing them first...

IMHO the seat post is always the first thing to check. Stand-up and see if the noise goes away.
