2025 Trek CHECKPOINT SL 6 AXS Gen 3 – Carbon Gravel Bike
The 2025 Trek Checkpoint SL 6 AXS Gen 3 is engineered for riders who seek extended gravel exploration, bikepacking adventures, and all-day comfort. Built around a lightweight carbon frame and Trek’s Gravel Endurance geometry, this bike delivers exceptional stability, efficiency, and comfort over long distances.
Featuring clearance for tires up to 50 mm wide, the Checkpoint SL 6 easily adapts to rough gravel roads, light singletrack, and mixed-surface touring. The frame and fork include extensive mounting options, making it ideal for racks, bags, bottles, and long-haul gear setups.
Comfort-Focused Performance
Trek’s IsoSpeed decoupler technology absorbs vibration from uneven terrain, reducing fatigue and keeping you fresher for longer rides. Combined with a slightly more upright Gravel Endurance geometry, the bike excels on multi-day adventures and endurance-focused gravel rides.
