At the Impec Lab, gravel isn’t just a category – it’s a playground without rules. A space where our engineers can stretch their muscles, experiment without constraint, and push the limits of performance and freedom.  

But gravel is also more than engineering. It’s a heartbeat, a rhythm that changes with every path. It’s the rush of speed across endless champagne gravel, the raw silence of a forgotten ridge, the thrill of dropping into a trail no one has ridden before. Gravel is freedom, adventure and discovery and it’s in this world without boundaries that our imagination finds its form. 

When we set out to create bikes for gravel, we didn’t just want to design machines. We wanted to capture that feeling. The awe, the laughter, the exhaustion that turns into triumph. Every ride we’ve taken, every climb that’s broken our legs, every descent that’s stolen our breath – all of it fuels what we create inside the Impec Lab. Here, ideas are tested against real landscapes, wild imaginations meet raw carbon and every prototype carries a story before it ever touches the trail.  

With this adventurous spirit in mind, we set out to develop our gravel range in a less than expected way. Taking all the lessons we had learned from both the road and MTB world, the Impec Lab got to work, chopping up frames, splicing ends together, 3D printing linkages, testing geo, pushing every limit. And they didn’t stop there, it’s one thing for them to feel a certain way about a bike but what about real people? Partnering with industry experts, the Impec Lab found a handful of real riders who were the test dummies for our early gravel bikes, and what would become the URS. 

From this passion, two distinct souls emerged. 

The URS: the adventurer. A companion built for freedom, light yet robust, born to leave the beaten path behind. For those who choose the unknown, who embrace rough trails and endless horizons, URS carries them further, with Micro Travel Technology (MTT) absorbing the chaos of the trail so the spirit can roam free. 

The Kaius: the racer. A pure expression of speed and precision, sculpted for performance at the edge of possibility. With ultra-light carbon engineering, aerodynamic integration and uncompromising stiffness, it transforms every watt into acceleration, every decision into control. From the first pedal stroke to the champagne on the podium, Kaius is built to chase victory where roads end.  

Together, they tell the story of BMC gravel: race fast, roam free. 

Because gravel at BMC is never just about the kilometers. It’s about the stories that live long after the ride ends. The silent moments, the shared laughter, the challenges overcome. And behind every one of those stories, there’s the relentless work of the Impec Lab – where no idea is too wild, no detail too small and where every innovation, from MTT to integrated cockpit systems, is born from the desire to turn raw materials into unforgettable rides.  

In the Impec Lab, we don’t just build bikes: we build possibilities, memories and experiences.
