The bolt features a hollow centre bore while the countersunk head has been internally machined to remove additional material from areas that don't contribute to strength.

The result is a beautifully engineered component that achieves maximum weight reduction while maintaining the durability and reliability expected from a critical headset fastener.

Manufactured to precise tolerances, the S-PARTS Hollow Core Headset Bolt provides consistent preload while complementing the clean aesthetics of today's premium road and gravel bikes.
