Product details

IN STORE PICKUP OR LOCAL DELIVERY ONLY

Long-distance exploration out toward the KVR or a full day on the Okanagan Rail Trail is where the Checkpoint SL 5 AXS Gen 3 comes into its own. This carbon gravel bike combines Trek's Gravel Endurance geometry with IsoSpeed technology to soak up vibration from rough surfaces, room for tyres up to 50mm, and a fully wireless SRAM Apex XPLR AXS 12-speed drivetrain that shifts precisely no matter how rough the road gets.

Drivetrain: SRAM Apex XPLR eTap AXS wireless electronic shifting, 12-speed, SRAM Apex 1 DUB Wide crank (40T), SRAM XPLR PG-1231 11-44 cassette

WHO IS THIS FOR?

This bike suits an adventure-focused gravel rider who wants a genuinely capable carbon build for long days exploring routes like the KVR or Okanagan Rail Trail, with the option to add a dropper post or suspension fork down the line. They'll appreciate the crisp, maintenance-friendly feel of wireless AXS shifting, the chatter-smoothing comfort of IsoSpeed, and the internal frame storage and mount points for carrying gear on multi-day trips.

Our team at Fresh Air will help you find the right fit in-store at both Kelowna locations. Stop by to work with one of our experienced staff members, or call 250-763-3425.

HOW TO SET UP

Our team can dial in your contact points — saddle height, reach, and cleat alignment — for the Checkpoint's Gravel Endurance geometry, and set tyre pressure appropriate for the mix of pavement and gravel you're riding, whether that's the KVR or the Rail Trail. We can also help fit racks, fenders, or frame bags using the integrated mounts, and talk through dropper post or suspension fork options if you're planning to upgrade. Drop into Fresh Air Pandosy (555 Groves Ave) or Fresh Air Dilworth (1656 Dilworth Drive), or book an appointment online.
