Trek has launched the CheckOUT, and it’s not just a new gravel bike — it’s a statement about where gravel cycling is headed. The CheckOUT is Trek’s first purpose-built full-suspension gravel bike, featuring a RockShox Rudy XL fork with 60mm of travel and a RockShox SIDLuxe rear shock with 55mm of travel. After years of watching competitors dip a toe into suspension with 30–40mm forks, Trek has gone further — and the result is a bike that challenges the assumption that gravel riding means absorbing rough terrain with your body.
Here’s a full breakdown of what Trek built, who it’s for, and how it fits into the rapidly evolving full-suspension gravel category.
What Makes the CheckOUT Different
Full-suspension gravel bikes are still a niche within a niche — most gravel bikes remain hardtails with at most a suspension fork, and many serious gravel riders prefer rigid setups for their simplicity and efficiency on smoother surfaces. What sets the CheckOUT apart is the degree of commitment Trek has made to the suspension platform.
60mm of fork travel and 55mm of rear travel is substantially more than competitors are offering. Giant’s Revolt X uses a 40mm fork. Canyon’s Grizl CF uses a Rift fork with similar short travel. These more conservative approaches maintain a road-biased feel. The CheckOUT, by contrast, is designed for riders who want to venture into genuinely rough terrain — double-track, chunky gravel, forest roads, and light trail — without the punishment of a rigid setup.
Trek has integrated the rear linkage into a clean frame design that manages weight carefully. They’ve paired the suspension platform with wide tire clearance (up to 50mm), a dropper post port, and geometry that prioritises control on technical terrain over aerodynamic efficiency. This is a bike for adventure, not for racing your training partner on smooth gravel paths.
The Checkpoint+ SL 6 AXS: Trek’s Electric Gravel Option
Alongside the CheckOUT, Trek simultaneously launched the Checkpoint+ SL 6 AXS — their first electric-assist gravel bike. Powered by a compact, lightweight motor integrated into the bottom bracket area, the Checkpoint+ uses Trek’s “micro-assist” philosophy: providing just enough assistance to extend range and reduce fatigue on long days, without the weight and visual bulk of a full e-bike system.
The target audience for the Checkpoint+ is gravel cyclists who want to explore bigger routes or ride with faster groups without getting dropped on the climbs. It pairs with SRAM AXS wireless drivetrain for a clean, cable-free aesthetic. Note that the Checkpoint+ is a distinct model from the CheckOUT — one is full-suspension, the other is electric. Trek is offering both as separate platforms.
The Case For Full-Suspension Gravel
Sceptics of suspension gravel bikes typically make three arguments: weight, efficiency loss, and maintenance complexity. These objections are legitimate for most scenarios — a rigid gravel bike with well-chosen tyres handles the vast majority of gravel riding with no meaningful disadvantage.
But as gravel riding has evolved, so has the terrain riders are tackling. The growth of ultra-distance gravel events like Unbound (formerly Dirty Kanza) and multi-day bikepacking routes has pushed riders onto progressively rougher surfaces for progressively longer periods. At that level of roughness and duration, suspension offers real benefits: reduced upper body fatigue, better control at speed over loose or chunky terrain, and increased confidence in technical situations where a front wheel wash-out would be catastrophic.
Trek’s CheckOUT is explicitly targeting this end of the gravel spectrum. It’s not a bike for every gravel rider — it’s a bike for those whose gravel rides look more like mountain biking routes than smooth gravel roads.
How Does It Compare to the Trek Checkpoint SL?
It’s worth clarifying the relationship between the CheckOUT and Trek’s existing Checkpoint SL Gen 3, which we covered recently. The Checkpoint SL is Trek’s performance gravel bike — rigid, fast, and optimised for mixed-terrain riding where smooth gravel and tarmac feature heavily. It’s the choice for competitive gravel events and fast group rides.
The CheckOUT is a fundamentally different product aimed at a different rider. If you’re racing or riding fast on groomed gravel, the Checkpoint SL is the better tool. If you’re bikepacking, exploring rough terrain, or regularly riding in conditions that punish a rigid setup, the CheckOUT makes sense.
Pricing and Availability
Trek has positioned the CheckOUT in the premium segment, reflecting the cost of quality suspension components and the additional engineering required. The entry model starts from around £4,999 / $5,499, with higher-spec builds featuring carbon frames and SRAM AXS available above that. The bike is available now through Trek retailers and the Trek website.
Given the price point, the CheckOUT is squarely aimed at experienced gravel riders who have identified rough terrain as a consistent part of their riding and want a purpose-built tool for it — not entry-level cyclists stepping into gravel for the first time. If you’re still working out what kind of gravel or e-gravel riding suits you, starting with a more affordable option makes more sense.
Key Takeaways
- Trek’s CheckOUT is the brand’s first full-suspension gravel bike: 60mm RockShox Rudy XL fork + 55mm SIDLuxe rear shock.
- More suspension travel than any current competitor, explicitly targeting rough bikepacking and adventure terrain.
- Simultaneously launched with the Checkpoint+ SL 6 AXS, Trek’s first electric gravel bike — a separate platform.
- Different use case from the rigid Checkpoint SL: CheckOUT for rough adventure, Checkpoint SL for performance on groomed gravel.
- From £4,999 / $5,499 — premium pricing reflects the suspension system and engineering investment.
