The Helium frame is our ultra-gourmet bike. It’s simply at the highest level when it comes to stiffness to weight ratio. We’ve designed it to be as light as possible to tackle the longest, steepest climbs. Yet it is stiff and durable enough to expertly handle the likes of Thomas De Gendt’s one-minute at 500W early breakaway effort. Hence, weight as well as performance is built into this frame as it must satisfy the most demanding of our pro cyclists.

The Helium is not only built for the pros, but is designed for anyone who wants to pull everything out of their bike. It’ll help you to be fast on the climbs to grab those Strava KOM’s, fly on the flats and rolling terrain, and sprint like a pro. It’s also comfy enough to keep you motivated to ride long distances to tackle Gran Fondos.

Compatible with both mechanical and electronic shifting.


The Helium SLX is the top of our ultra-gourmet Helium line of bikes. For this model our engineers really went to the edges to create the lightest frame possible, without losing any stiffness. Thanks to the more traditional, but sublime tube shapes it’s the lightest frame of them all, barely tipping the scale at 750g for a size medium. The ultra-thin seat stays are engineered to offer comfort enhancing vertical compliance and lateral stiffness.

Our Soudal Lotto pros are mad about this bike, which they have used in all conditions: from queen stage wins on the Mont Ventoux to the victory in the Strade Bianche.

If vertical speed is your thing, this is the ideal bike for you. Simply tap on the pedals and up you go! It is also incredibly stable through high speed turns and descents thanks to the straight blade fork.
