Description

Intelligence Meets Velocity: Trek Supercaliber SLR 9.9 Flight Attendant (2025)

The Trek Supercaliber SLR 9.9 Flight Attendant represents a paradigm shift in mountain bike performance. Built on the elite SLR OCLV Mountain Carbon chassis, this Gen 2 frame is paired with the RockShox Flight Attendant system—an integrated suite of sensors that automatically adjusts your fork and rear IsoStrut suspension in real-time. By analyzing rider input and trail terrain every 5 milliseconds, the bike switches between Open, Pedal, and Lock positions, ensuring you are always in the most efficient state without ever touching a lever.

The build is uncompromising, featuring the SRAM XX Eagle Transmission for flawless wireless shifting under the heaviest race loads. To ensure maximum acceleration, it is equipped with Bontrager Kovee RSL Carbon wheels, which offer pro-level stiffness and an ultralight profile. With 80mm of integrated IsoStrut rear travel and a 110mm SID Ultimate fork, this electronic XC race MTB is the ultimate choice for riders who want the smartest, fastest machine on the World Cup circuit.

Automated Efficiency & SLR Carbon Engineering

The Supercaliber SLR Flight Attendant eliminates the mental fatigue of racing. While other riders fumble with remote lockouts, your suspension is already optimized for the next climb or descent. The SLR carbon layup provides the stiffest, lightest platform possible, while the updated Gen 2 geometry offers the stability needed for modern, “downcountry” style XC tracks. This is the flagship Trek XC bike, designed for the singular purpose of winning.
