The S5 has one job—get to the line before everyone else. Under the likes of Wout van Aert, Marianne Vos, and Christophe LaPorte, the new model has already proven itself as a tool without equal. The new S5 has reduced drag while increasing the frame’s surface area and still reducing overall weight, and a ground-breaking new wheel design concept co-developed with Reserve increases stability and reduces drag in turbulent aero conditions.

In pursuit of speed, everyone wants to try different positions to find their most aggressive fit. The S5's iconic V-stem not only inspires confident handling at high speeds, it's now also remarkably simple to dial in your perfect set-up.

Wider wheels and tires are faster aerodynamically, and more comfortable to boot. S5 comes specced with 28mm tires but has clearance for up to a 34mm (measured) tire. The frame is optimized to complement the wider Reserve turbulent aero wheels.

The UCI’s new regulations on aerodynamic design allowed us some additional room to deepen our aero profiles and squeeze more grams of drag performance out of what is already the fastest aero bike on the market.
