FSA Orbit C-40 ACB No. 42 Headset Bearings - Blueseal Bike Bearings™
This Blueseal Bike Bearing kit contains the upper and lower headset bearings needed to replace your FSA NO.42 headset bearings.




Seal Design
Blueseal Bike Bearings™ have top-quality rubber seals. The better the seal harder it is for water and dirt to get in and the grease to get out! This is the most important feature for a bike bearing.
Premium Grease
Blueseal Bike Bearings™ contain Mobil XHP 222 grease. Standard stock bearings are designed for use in machinery and contain very little amounts of non-specific bearing grease (Approx. 20%) This offers little protection against rain and dirt ingress.
Premium Waterproof Grease
Mobil XHP 222 is a premium marine-specific grease with high washout resistance that is designed for use in poor conditions. This means the grease stays in the bearing for longer and offers the best protection against dirt, rain and muddy water.
Strong Composition
Blueseal Bike Bearings™ are built using the best quality materials, this higher class of bearing run smoother & last longer.

Cervelo headset bearings
Great headset bearings, gone were the gritty rough bearings and in with the silky smooth blue seal bearings.

Grabbed a set of headset bearings to replace my worn set and headset feels like new for a quarter of the price of buying a full headset, great quality and easy to fit
