Headset question.

[Hacienda71]

I have a FM098 frame that needs a new headset. The spec for the frame says it is a 1 1/8 to 1 1/2 integrated jobbie, would the attached link be OK or are there lots of different factors to consider on tapered headsets on road bikes? Cheers for any pointers.

I know there are two factors to do with the angles on the bearings to fit the frame. Some are 45 X 45 and some 45 X 36.

I only know mine is 45 X 36 because I took the bearings out and it's written on the outer edge. Worth checking

You need to match the new bearings exactly re these things:

OD - Outside Diameter (You can get by with very slightly smaller OD's.)
ID - Internal Diameter (you already have these correct)
Depth - very important they must be more or less the same depth - definitely no thinner)
Angle - as Fossyant says the angles should be written on the side.

don't buy a headset direct from China - the quality of the bearings will be crap!

Cheers chaps, have emailed the manufacturer to ask for the full spec.

The bearing angles are the contact angles between the crown race and the bearing aren't they? As long as you fit the appropriate crown race and compression bung, the angle of the bearings won't make a difference. It generally only changes on the crown race. I stand to be corrected though. That headset looks to have its own crown race, and what's more it's split, so will be tool less fitting.

Agreed!

You can get a reputable branded headset for as little as £20. Don't buy a cheap headset, please!

Bought from Wiggle, fitted works fine.
