About Helium SLX

The Helium SLX is the lightest bike in the Helium road bike range. Our engineers went to great lengths to perfectly balance weight and stiffness. The more traditional yet sublime tube shapes make this the lightest road frame of all, weighing in at barely 750 grams for size medium.

To ensure for comfort without sacrificing a single watt are the uniquely shaped ultra-thin chain stays. While the fork on this high-performance bike provides an incredibly stable feeling, even on the fastest, trickiest descents.

The Helium SLX has received exceptionally high praise all around, to include victories at the modern race classic of Strade Bianche and to the top of Mont Ventoux. If you're keen on instantly riding faster, the Helium SLX is for you!

About the helium family

The Helium bikes are the very best all-round road bikes for the most demanding cyclists. These high-performance machines are incredibly stiff and durable yet ultra-light to dance up impossibly steep climbs. They also handle like a dream when flying at top speed on challenging descents. This is what makes them frame favourite of the Lotto Soudal pro cyclists.

While their classic, round tubing may deliver the best balance of weight vs stiffness and reactivity vs comfort, it surely doesn't help them to stand out from the crowd. What instead earns them their insanely high performance marks in every bike test are their sublime riding characteristics. In a nutshell, this bike instantly lifts the cycling level of every rider - in every way.
