Cervelo S5 Ultegra Di2 700c Bike - Five Black

The S5 has one job—get to the line before everyone else. 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. Undisputedly the fastest bike of the modern era

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, 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 Enhancement - The UCI’s new regulations on aerodynamic design allowed Cervelo some additional room to deepen 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, they 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 - Cervelo improved the comfort, and tweaked the shape of the handlebar to get a perfectly flat bar-to-hood transition. The S5 now uses a two-bolt interface that allows for infinite tilt adjustments between 0 and 5 degrees
Keeping it Simple - Bike fitters at every level are moving away from longer-offset seat posts, and the new S5 comes stock with a 15mm offset post on most sizes (vs 25mm offset on outgoing S5). The old seat posts are forward-compatible, and Cervelo will keep the 400mm-long, 25mm offset post in stock for those looking for a more extreme fit
