Help me solve the creaking crank!

apoc_reg

Hiya,

My crankset is shimano XTR and not long after i got them i started to get some annoying creaking when pedalling hard (uphill or standing up etc). I thought I was just unlucky with my set so i brought some replacement cups (http://www.chainreactioncycles.com/Mode ... elID=38336).

For a short while they were great but after a week or so they are doing it again!

For cleaning I use muc off degrease on my chain, rinse followed by muc off, rinse and then bike spray water disperser/protector. I also usually put some GT85 on the chain/crank area and obviously normal chain lube.

Could one of those be causing the problem.... or something else? I don't want to buy another set only for the same thing to happen again

Thanks a lot

There is a sticky on this website covering creaks.

The two ones to check first for me are

1: Chainrings TIGHT

2: handle bars on tight (seriously) Cos when you put power through the pedals, what are you pulling against?

Whats a good grease to use if i have to take my BB apart?

Thanks

BB is ball bearing I think, I had replaced mine when mine was 'creaking' :P

It's a cheap job

Cheers guys, got plenty to go on now!!

Next time im going to buy a crankset that doesnt need 3-4 specialised tools though

It wasnt the drivetrain at all, its the suspension pivots. Will have to look at getting them serviced!
