Trek Checkpoint SL5 AXS - Black - M/L

The Checkpoint SL 5 AXS Gen 3 is an adventure-ready carbon gravel bike built to roll into the distant horizon. It features a lightweight 500 Series OCLV Carbon frame designed with a comfort-focused geometry, room for beefy 50mm gravel tyres, and an abundance of integrated frame and fork mounts for bikepacking gear. To keep you fresh over long miles on unsealed paths, Trek's IsoSpeed comfort technology helps soak up jarring road vibrations, helping you float smoothly over chatter, ruts, and potholes. It comes equipped with a wireless 12-speed SRAM Apex XPLR AXS electronic drivetrain to deliver reliable, crisp shifting when exploring the dusty backroads.
