Trek Checkpoint SL 5 AXS Gen 3 Bike 2026 Trek Black/Matte Carbon Smoke

Point it down dusty backroads and keep the rhythm smooth when the surface gets rowdy—the Trek Checkpoint SL 5 AXS Gen 3 is built to turn long gravel days into fast, grin-filled miles. Trek pairs adventure-ready handling with confident stability so you can push pace, load up, and keep rolling when the route goes off-script.

The Trek frame uses 500 Series OCLV Carbon with IsoSpeed vibration damping, clearance for 50mm tires (as measured), and integrated downtube storage for tools. SRAM Apex XPLR AXS wireless 12-speed delivers crisp shifting across 11–44T gearing, while tubeless-ready Bontrager wheels and Girona RSL 700x42mm tires keep speed and traction balanced on rough gravel.
