I'm fitting this Cane Creek internal headset to a Trek 2000.

The old headset was a Bontrager one and the bearings just lifted out but the new bearings (although the angles are the same and it's a 1 1/8th) are too tight to go in.

I don't want to force them in so what gives? I thought these internal bearings were just meant to go straight in?

Put them in the freezer for now while I'm figuring it out.

    Download the headset technical guide from the FSA website - it has all the key dimensions - some models vary as little as 0.2mm in bearing diameter which would probably explain the interference fit.
    Make mine an Italian, with Campagnolo on the side..
