Why We Like The P5 Ultegra Di2 Road Bike

Cervelo's knowledge of road racing goes deep, and that's part of why we think the P5 Ultegra Di2 Road Bike excels in terms of speed, handling, and agility. The brand applied years of experience in engineering the fastest aero bikes with real-world feedback from pro athletes to make for a bike that pushes the limit in every mentionable way. This is the bike we want for time trials and triathlons, and it's the bike we need for speed. Electronic shifting gives us every advantage and remains as reliable and precise as ever, and leading aerodynamics gives us wind-slicing advantages for our racing endeavors.

The P5 is our bike of choice for time trials and triathlons due to its responsive handling, aerodynamics, and speedy engineering. The Speed Riser (Cervelo's user-friendly aerobar system) is easily adjustable to a mess of positions so we can customize our fit and make simple adjustments with a single tool. In addition, tidy cable management hides brake and shift control lines from the wind without compromising for usability or performance. Cervelo also optimized the stiffness of the head tube and bottom bracket for stable and predictable handling that improves power transfer for efficient forward momentum. This, of course, means there's no wasted effort when we're pushing ourselves to our limit.
