The Cervelo S5 Dura-Ace Di2 Bike is what happens when a brand commits fully to aerodynamics and then keeps refining. The S5 isn't the lightest road bike Cervelo makes — that's the R5's job. The S5 exists to slice through the air faster than anything else at this price, and it does so with a precision that has made it the bike of choice for some of the best riders in professional cycling. Jonas Vingegaard and Wout van Aert have won races on it. Simon Yates has won races on it. The current generation is 6.3 watts faster than its predecessor while simultaneously shedding 124 grams — an improvement in two dimensions that doesn't happen by accident.

The aerodynamic gains are concentrated at the front end. Cervelo went significantly deeper on the fork legs and refined the head tube profile, producing smoother airflow into and around the frameset. The asymmetric seat tube profile integrates with the rear wheel as a cohesive system — air coming off the frame feeds cleanly into the wheel, not around it. This is not incidental. The Reserve 57|64 wheelset was co-developed with Reserve specifically for the S5's geometry, with the rear wheel's asymmetric profile engineered to match the seat tube cutout exactly. Those wheels are 3 watts faster than the previous Reserve 52|63 pairing while maintaining equivalent weight. Every aero gain on this bike compounds on the one before it.
The HB19 one-piece carbon bar and stem uses Cervelo's "Plus-Four" concept: the hood position is 4 centimeters narrower than the drops. This allows riders to hold a more aerodynamic position on the hoods — where most riding actually happens — without sacrificing stability during sprints or technical descents. Nine bar and stem size combinations are available, so achieving an aerodynamically optimized fit doesn't require compromise. The frame accepts those nine configurations at no additional cost when purchased through an authorized retailer, and the design is fully UCI-legal.
The drivetrain is Shimano…
