The 2023 Trek Procaliber 9.7 GX AXS is a lightweight, race-focused hardtail built for speed and efficiency on cross-country terrain. Its standout feature is the IsoSpeed decoupler—a unique design that allows the seat tube to flex independently from the top tube, offering a smoother ride without the weight penalty of full suspension. With a 100mm Fox Factory 32 Step-Cast fork, fast-rolling 29” wheels, and geometry tuned for quick handling and efficient power transfer, the Procaliber 9 is designed to excel on climbs and pedal-heavy courses. It comes equipped with SRAM GX AXS 12-speed drivetrain and Bontrager Kovee Elite tubeless-ready Carbon fiber wheels, making it a strong contender for riders who prioritize speed, efficiency, and comfort during long, demanding XC races.
