{"product_id":"cervelo-p5-ultegra-di2-bike-1","title":"Cervelo P5 Ultegra Di2 Bike","description":"\u003cdiv\u003e\n\u003cp\u003eThe \u003cstrong\u003eCervelo P5 Ultegra Di2 Bike\u003c\/strong\u003e is the entry point into Cervelo's flagship triathlon platform — the same aerodynamically engineered frame, the same adjustable Speed Riser cockpit, and the same geometry that has put athletes on Kona podiums and World Championship start lines, built around Shimano's proven Ultegra Di2 12-speed electronic drivetrain. At $10,650, it makes the P5 platform accessible without compromising on the frame technology or fit system that make the P5 one of the most respected triathlon bikes in the category.\u003c\/p\u003e\n\u003cp\u003eThe P5 frame was developed through Computational Flow Design validated in real wind tunnels, with Strike-shaped tube profiles engineered to minimize drag across real-world yaw angles — the kind of conditions athletes actually face on open race courses, not just controlled tunnel environments. In standard disc brake configuration, the frame produces 1,872g of aerodynamic drag. The TrueAero rear wheel cutout maintains a precise 2–6mm frame-to-tire gap with wheels up to 28mm in depth and tires up to 25mm wide, so athletes who run multiple wheelsets across different race conditions don't give up aerodynamic efficiency when they swap. The Fastback seatstay design improves rear compliance by approximately 22% compared to the previous P5 generation, and the Comfort Ply layup technology uses different carbon materials tuned in different orientations throughout the frame — independently controlling stiffness, weight, and road compliance zone by zone rather than accepting a single-material tradeoff across the chassis. The result is a frame that's 22% stiffer at the head tube and 26% stiffer at the bottom bracket than the generation it replaced, while riding with noticeably less road-induced harshness over long race distances.\u003c\/p\u003e\n\u003cp\u003eThe Speed Riser cockpit is one of the most adjustable integrated aerobar systems on a production triathlon bike. The 380mm basebar pairs with aerobars that adjust from 0 to 30 degrees in 5mm increments, with 95mm of fore-aft reach adjustment and 45mm of pad reach — enough range to place most athletes in a legal and comfortable race position without sourcing aftermarket components. Extensions ship in a 30-degree bend; 50-degree and S-bend configurations are also available. The D-shaped steerer routes hydraulic brake lines internally, keeping the cockpit aerodynamically clean from stem to hub.\u003c\/p\u003e\n\u003cp\u003eThe drivetrain is Shimano Ultegra Di2 R8150 — 12-speed electronic shifting that's earned a reputation for reliability and precision across thousands of miles of training and racing. Ultegra Di2 is a wired electronic system, which means consistent shifting performance without the battery management of a wireless setup and a well-understood service and maintenance profile. The Shimano Ultegra crankset runs a 52\/36T chainring configuration — a setup that suits both flatter and hillier triathlon courses — paired with an 11-30T cassette for tight gear steps through the middle of the range. Braking is hydraulic disc throughout, with 160mm Centerlock rotors front and rear. The wheelset is Fulcrum Racing 400 DB — a tubeless-compatible alloy wheel on 12mm thru-axles front and rear, a functional and durable starting point that many triathletes choose to upgrade as they move deeper into race-focused training. Vittoria Corsa Speed TLR tires are fitted tubeless-ready. The Cervelo SP23 carbon aero seatpost pairs with a Prologo Dimension Tri saddle, and the seat tube runs the P5's full 75–79° adjustable angle range to accommodate a wide range of triathlon-legal fit positions.\u003c\/p\u003e\n\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull P5 aero platform.\u003c\/strong\u003e The same TrueAero wheel cutout, Strike tube profiles, and Comfort Ply layup as the top-spec P5 builds — the frame technology doesn't change between builds, only the components on it.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeed Riser cockpit with 95mm reach adjustment.\u003c\/strong\u003e 0–30° extension adjustment in 5mm increments gives most athletes a legal, comfortable fit without aftermarket modifications.
