Shown for the first time at Bespoked 2025 in Dresden — the world's leading handmade bicycle show — this Ceres GT concept build is our answer to a question we keep hearing from serious gravel riders: can a bike be both fast and responsible?
The answer is yes. This build pairs the race-ready geometry of the Ceres GT with some of the most thoughtfully engineered components available.
Performance meets sustainability
The Tout Terrain Ceres GT is designed for riders who want performance, comfort, and environmental awareness in a single package. The Thermocrom CrMo steel frame combines long-term durability and repairability with carefully selected components for a uniquely smooth ride across any surface.
Chris King FusionFiber Wheels
Chris King's FusionFiber wheels are made from recycled composite material — lightweight, stiff, and comfortable, while carrying a significantly smaller environmental footprint than conventional carbon wheels. Paired with the Tout Terrain gravel fork and bikepacking-ready setup, they're as capable on fast gravel as on rough mountain roads.
SQlab Gravel Cockpit
An ergonomic cockpit designed for comfortable handling and reduced fatigue on rough surfaces — because being fast on gravel means staying comfortable for the long haul.
Thermocrom CrMo Frame
Our Thermocrom tube set takes frame construction to the next level. Through heat treatment of the steel, we can strategically use thinner-walled tubes in specific areas — reducing weight without compromising toughness. The result: a frame that rides with the classic feel of steel, tuned precisely for gravel performance.
SRAM Force XPLR 13-Speed
Electronic gravel shifting with a wide gear range for smooth, reliable performance in any conditions. No more fumbling at the top of a climb — the Force XPLR shifts instantly whether you're sprinting or grinding.
Hope Carbon Cranks
Light and stiff, made by Hope Technology in the UK. Optimized for gravel performance and built to last.
The Ceres GT Custom is a concept build. The Ceres GT Select 5.1 — our production gravel bike — is available now for immediate shipping from Tucson, AZ.
