This bike suits an experienced gravel or all-road rider looking for a lightweight, race-capable machine built for long mixed-surface days — someone tackling the KVR, linking up the Okanagan Rail Trail, or planning multi-day bikepacking trips through the valley. They'll appreciate the crisp wireless shifting of SRAM Rival AXS E1, the smoothing effect of IsoSpeed over washboard gravel, and the built-in storage and mounts for carrying gear on longer excursions.

Frame geometry and sizing details for the Trek Checkpoint SL 6 AXS Pro Gen 3 are available on the Trek website. Trek offers the Checkpoint SL 6 AXS Pro Gen 3 in sizes XS through XL. Our team at Fresh Air can help you find the right frame size based on your height, inseam, and riding style — come in to either Kelowna location and we'll get you dialled in.

Our team can dial in your contact points — saddle height, reach, and cleat alignment if you're running clipless pedals — and set your tire pressure to suit whatever mix of pavement and gravel you're riding, from smooth valley roads to rougher stretches of the KVR. Since the Checkpoint SL 6 AXS Pro runs SRAM's wireless AXS system, we'll also confirm your shifting is paired and functioning perfectly before you leave the shop. We can set up the stock Bontrager tires tubeless, and we offer ongoing service and tuning for the SRAM AXS drivetrain year-round.
