Details

Headset bearings are angular-contact cartridges: the outside diameter, inside diameter, height and the two seat angles all have to match your frame's head tube and fork crown race. The numbers are usually printed on the old bearing's seal.

Fit

Press-fit. Press on the outer race only when fitting — hammering the inner race brinells the bearing. Sold individually; a headset takes one upper and one lower bearing, which can be different sizes.

FSA bearings are covered against defects in materials and workmanship. Wear from contamination, water ingress, incorrect fitting (pressing on the wrong race) or use in the wrong application isn't covered.

For warranty support, return the item to Tune Cycles with your proof of purchase and we'll manage the claim with the distributor for you. This cover is in addition to your rights under the Australian Consumer Law.
