This Blueseal Bike Bearing kit contains‚ the upper and lower headset bearings needed to replace your‚ Hope 1 1/8" to 1.5" headset bearings. 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 get out.
