Built to deliver speed, aerodynamics, and triathlon-ready practicality, the 2026 P-Series Ultegra Di2 in Basalt is a no-compromise time-trial / triathlon machine — engineered for athletes who demand performance, versatility, and simplicity in one sleek package.
Performance & Aerodynamics — Race-Born, Real-World Ready
-
The P-Series inherits aerodynamic heritage from the flagship P5, with a redesigned frame that is 5.9 g faster than the previous generation.
-
Expanded wheel and tyre clearance accommodates larger tyres and Reserve carbon wheelsets, giving you the option to prioritise speed or comfort depending on the terrain.
-
Internal cable routing and clean integration reduce drag and enhance the bike’s sleek, purposeful profile — ideal whether you’re slicing through wind on the way to T1 or hammering on a long time trial leg.
Triathlon-Ready Practicality — Storage Meets Speed
-
The 2026 P-Series introduces in-frame storage — cleverly hidden yet easily accessible. There’s space for an inner tube, multi-tool and CO₂ cartridge — all without compromising aerodynamics.
-
Included “Smartpak 400” top-tube bento box adds race-day convenience, giving you quick access to nutrition or gels while maintaining clean lines and minimal drag.
-
For triathletes or TT riders juggling transitions, hydration and fueling, this integrated storage plus aero-optimised build makes the P-Series a practical “one-bike” solution.
Components & Build Quality — Reliable, Premium, Complete
-
Shimano Ultegra Di2 12-speed drivetrain (52/36T crank, 11–30T cassette) ensures smooth, precise shifting under load and over long distances.
-
Crank-mounted dual-sided 4iiii power meter provides accurate power data out of the box — essential for pacing, training and race optimisation.
-
Aerodynamic Reserve carbon wheels (front / rear) and Vittoria 700×29c tyres strike a balance between aero profile, rolling efficiency and ride comfort — whether on smooth road or rolling terrain.
-
Carbon P-Series frame with tapered P fork, D-steerer and round-stem interface offers both aerodynamic advantage and compatibility with a wide range of clip-on aero bars / cockpit setups — letting riders fine-tune fit and ergonomics.
Who This Bike is For
This P-Series Ultegra Di2 (Basalt) is ideal for:
-
Triathletes and time-trial riders seeking a competitive, race-ready rig straight from the box.
-
Riders who value aerodynamic performance but also appreciate practical touches — integrated storage, hydration / nutrition mounts, and a complete component build.
-
Cyclists who want a high-end build without extensive aftermarket modification — everything needed for fast, efficient riding is included.
