Headset Bearing Kit: 2 x Bearings (Upper & Lower) to fit headset on Cervelo R3, R5, S3 and S5

Note, this kit consists of 2 bearings only. Any picture of a complete headset or bike included is for reference to headset/bike the 2 x bearings fit.

Upper Bearing Dimensions: 30.15 x 41 x 6.5mm (chamfers 36/45 degrees)

Lower Bearing Dimensions: 37 x 49 x 6.5mm (chamfers 36/45 degrees)

Please check these dimensions against what you have fitted to your headset, as brands can sometimes change their specification without warning.
