The Tangeseiki #1718 is a precision cartridge headset bearing designed for modern bicycle steering systems. Engineered for smooth rotation and consistent performance, it supports stable handling under demanding riding conditions.

Bearing Design: This is a sealed cartridge bearing that integrates the races, balls and seals into a single unit. The closed construction helps maintain smooth operation while reducing maintenance requirements over long-term use.

Steering Interface: Built with a 45°/45° angular contact profile, the bearing ensures proper load distribution between the headset cups and the fork steerer. This angle configuration enhances steering accuracy and frame compatibility.
