Position One Integrated Headset 1-1/8"

Product Overview

The Position One Integrated Headset is a sealed-bearing headset designed for 1-1/8" integrated headtube frames and forks. It features angular contact bearings and lightweight aluminum components, delivering reliable steering performance with minimal maintenance across trail and cross-country riding.

Key Features

• Angular Contact Bearings (45° x 45°) - Dual-angle bearing races distribute steering loads efficiently; reduces friction and improves handling precision during directional input
• Sealed Annular Bearing Cartridges - Labyrinth seals keep contaminants and moisture out while retaining grease; extends bearing life and reduces service intervals compared to open bearings
• Lightweight Design - 80 g total weight minimizes rotating mass at the front end without sacrificing stiffness or steering response
• Aluminum Cover and Compression Star - CNC-machined components ensure precise tolerancing and consistent bearing preload; eliminates play for crisp steering feel
• Integrated Mount System - Proven integrated headset architecture compatible with modern 1-1/8" standard frames and forks
