This bike suits an adventure-focused gravel rider who wants genuine suspension comfort for long days on rough, chunky terrain like the KVR corridor, or for multi-day bikepacking trips that mix gravel roads with light singletrack. They'll appreciate the flared GR CheckOUT bar's multiple hand positions, the wide 56mm tyre clearance for rougher surfaces, and the integrated rack and frame bag mounts built specifically for hauling gear.

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.

Our team can dial in your contact points — saddle height, reach, and cleat alignment — for the CheckOUT's Gravel Adventure geometry, and set sag and rebound on the RockShox Rudy XL fork and SIDluxe rear shock to match your weight and riding style. We'll set up your Bontrager tyres tubeless with the right pressure for the terrain you're riding, whether that's the KVR or rougher backroads, and help mount the integrated rear rack, frame bags, or the optional Topo Designs frame bag for bikepacking setups. Drop into Fresh Air Pandosy (555 Groves Ave) or Fresh Air Dilworth (1656 Dilworth Drive), or book an appointment online.

Q1: What size Trek CheckOUT SL 5 do I need?
The CheckOUT SL 5 comes in five sizes — S, M, ML, L, and XL — built on Trek's new Gravel Adventure geometry, with handlebar width, stem length, and crank length scaled to each size. General sizing follows your height and inseam, but the best way to confirm your size is an in-person fit — our team at either Kelowna location can get you set up correctly.

Q2: Is the CheckOUT SL 5 right for riding the KVR or bikepacking?
Yes — with full suspension, wide 56mm tyre clearance, an integrated rear rack, and 18 frame mounts, the CheckOUT SL 5 is purpose-built for rougher gravel like the KVR corridor and multi-day bikepacking trips.

Q3: What tyre width and clearance does the CheckOUT SL 5 support?
The CheckOUT SL 5 ships with 700x50mm Bontrager Betasso RSL GX tyres and has clearance up to 56mm (2.2") as measured, giving plenty of room for rougher terrain while the suspension handles the rest.
