Cervelo S5 Force ETAP 51cm Sapphire/Ice

The new S5 has reduced drag by 65 grams and increased the frame's surface area while still reducing overall weight. The deeper frame sections maximize the shapes allowed by the UCI. Meanwhile, the iconic V-stem has been further refined, and a new fork designed to simplify the entire front end.

What's more, a ground-breaking new wheel design concept has been co-developed with Reserve to increase stability and reduce drag in turbulent aero conditions.

- V Is For Velocity
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, but it's now also remarkably simple to dial in your perfect set-up. All the necessary spacers come with the bike, and there’s now only one bolt length, reducing complexity and making the system 53g lighter in the process.

- Frame Enhancements
The UCI’s new regulations on aerodynamic design allowed us some additional room to deepen our aero profiles and squeeze 65 more grams of drag performance out of what is already the fastest aero bike on the market. You’ll notice a deeper head tube and BB area, and more aggressive shaping on the trailing edges of the tubes. Since the new S5 is only compatible with electronic shifting, we were able to tidy the dropout a bit and update the shaping all over the bike.

- Tire Clearance
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 52/63 turbulent aero wheels. In addition to the handling benefits, this saves over 5 watts compared to the previous Reserve wheelset.

- Handlebar Refinement
We’ve improved the comfort of the handlebar and tweaked the shape to get a perfectly flat bar-to-hood transition. We now use a two-bolt interface that allows for infinite tilt adjustments between 0 and 5 degrees.
