Bespoked 2025 Concept Bike: Ceres GT Custom

Tout Terrain Ceres GT Custom concept bike at Bespoked 2025

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.

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.
