Headset bearing's?

[DWiggy]

Hi Guys,
My bikes in need of replacement headset bearings (creaking and grinding), I have a BMC Street racer SR02 2011 that originally came from Evans:

FSA (45x45)
Does anyone know what size bearing and where to get them from?
Was kind of hoping these would do;

Many thanks in advanced and sorry for the stupid question but I'm getting a little confused

Your important bit is the 45 x 45 and 1 1/8th.

Mine are FSA 36 x 45. Both common

That link is a 36 x 45 according to the reviews, so won't fit.

I'll look for you.

Cheers mate I'm a little lost

Buy one of these - just use the bearings and keep rest for spares. Saves a load of faffing about trying to find them:

You need to identify the headset type first.

Integrated headsets are also known as drop in headsets as the bearing just drops in the head tube.

Semi -Integrated have a race which fits into the headtube and then the bearing is introduced.

I presume you have an integrated headset.

Bearings come with 3 variables.

1) Angle of bevel on the inside and outside - yours is 45 x 45.

2) The depth 6mm or so

3) The outside diameter of the bearing or inside diameter of the headtube.

You need to get all three right.
