✔️ One 40mm Bore 51.9mm Cup Eight Millimeter Wide Angular Contact Set

You grab a single sealed angular contact bearing made exactly for your fork steerer tube. Swapping these past worn steel races brings back twitchy control on neighborhood laps or paved weekend miles. Your steering feels noticeably tighter with zero lateral slack.

- The fixed forty five degree race tilt kills handlebar shimmy when sprinting out of turns.
- This configuration is a handy upgrade that plugs dead play from your steerer assembly.
