CervéloP-Series

Triathlon20272024 version ↗Disc brakesUCI legal

Cervélo's lower-priced UCI-legal triathlon and time-trial bike, based on P5 aerodynamics. It uses a D-shaped steerer with a standard round stem interface so riders can fit any basebar and extensions. The 2024 redesign added more tyre clearance, Cervélo's first in-frame storage compartment and up to 53 mm of stack, across six sizes.

Our verdict

Overall

out of 100, average of 6 categories

A versatile, UCI-legal race bike with P5-derived aero and a standard stem, so any basebar and extensions fit and packing is simple. Builds now run from mechanical 105 to a 1x Classified Ultegra Di2, and six sizes with a 75-79 degree seat angle range suit most riders. The downtube storage hatch rules out an aero downtube bottle.

NotesSingle-chainring (1x) build.—Single 58T chainring with a Classified two-speed rear hub instead of a front derailleur. Sold in Chainsmoke, listed on the US store only. Cervélo lists 12.74 kg for this build, which looks implausible next to the 9.47 kg Ultegra Di2, so no weight is given here.—Single-chainring (1x) build.—Cervélo's US data lists the frameset at $3,000 but hides it from the US build list, so only the EUR price is given here.

Compare on the stack & reach chart

Good to know

  • Fit

    The D-shaped steerer with a round stem clamp accepts most aftermarket basebars and extensions. Maximum stack is 53 mm, and spacers to reach it are included.

    Source
  • Integration

    The 2024 frame is Cervélo's first with internal storage: a removable downtube hatch holds a tube, small multi-tool and CO2, and the lock can be flipped open with a bottle still in place.

    Source
  • Integration

    The storage hatch means the frame can't take the aero downtube bottle used on the previous P-Series and on the P5. Triathlete counted this as the main drawback for long-course racers.

    Source
  • Compatibility

    The added tyre clearance is designed around Reserve 52/63 wheels and 29 mm Vittoria tyres. Cervélo does not publish a maximum tyre width on the product page.

    Source
  • Racing

    Triathlete's tester found handling quick in corners and stable in crosswinds, but straight-line tracking was less 'autopilot' than some tri-specific bikes.

    Source
  • History

    The P-Series was redesigned in 2024, shortly after the updated P5. It borrows the P5's look, including the S5-style seat tube, top tube and seat stay junction.

    Source
  • Versions

    The range also includes a Rival AXS build ($6,950 / €6,499 / £5,500) and a mechanical Shimano 105 build ($5,300 / €5,299 / £4,500) that uses Vision TC60 wheels and microSHIFT bar-end shifters.
