The Truvativ Innenlage GXP XR Fatbike bottom bracket is designed to deliver reliable power transfer and long-lasting performance on the most demanding fatbike adventures. Built around Truvativ’s proven GXP interface, it provides a secure, creak-free connection between your crankset and frame, helping you convert every pedal stroke into forward motion, even in deep snow, loose sand, or muddy trails. Its robust construction is tailored for the wider spacing and unique demands of fatbike frames, ensuring proper chainline and smooth rotation under heavy loads.
This bottom bracket is engineered to handle harsh riding conditions, with high-quality sealed bearings that help keep out water, grit, and salt. That means less maintenance and more time riding, whether you are exploring winter singletrack or tackling all-season bikepacking routes. Compatible with GXP cranksets and fatbike-specific bottom bracket shells, the Truvativ Innenlage GXP XR Fatbike offers an easy upgrade or replacement option for riders who value durability, stiffness, and consistent performance in extreme environments.
