This, coupled with our hand-selected and matched parts-pick, allows us to offer daily ride-capable builds under 6kg.
Unmatched strength in our weight class. We’ve developed an incredibly rigid tail section and a specifically engineered IsoTruss® tube system designed to transmit pedal power without transmitting harsh vibrations.
The Vortex provides the best ride characteristics with lightning-fast acceleration, featherweight climbing, tyre-ripping cornering, and a definitive aero advantage. The Vortex twists all the best into one distinct, perfect package.
