Helium SLX Disc Size S
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.
The Helium / Aura frame is at the absolute highest level when it comes to stiffness to weight ratio. We’ve designed it to be as light as possible (750g for SLX size M) to tackle the longest, steepest climbs. Yet still stiff and durable enough to take the likes of Tiesj Benoot (Lotto-Soudal) putting his power on it in the Strade Bianche race. We’ve not just focused on weight but performance since it has to satisfy the most demanding of our pro cyclists.
It’s all in the tubing, especially with the Helium as it is easily our most complicated frame. The shape of the tubing has to be exact, including its tapering for selective lateral, vertical and horizontal stiffness. Some of these details can be seen when simply looking at the frame, such as the inner bulge of the chainstays for added lateral stiffness.
Don’t think that this stiff featherweight is losing its comfort. Its longer head tube adds that extra adjustability option for raising the handlebar a bit for a more comfortable riding position during the long distances. These details give the Helium / Aura that feeling of floating in air while maintaining the stiffness needed for exemplary power transfer.
