ACROS AZX 203 Headset Bearing Kit | Blueseal Bike Bearings
£21.24
Blueseal Bike Bearings™ are Bicycle Specific Bearings. The tighter the seal is to the inner bearing race, the harder it is for water and dirt to get in — and the harder it is for grease to escape. Most non-bike-specific bearings are ABEC 1.
