Cervelo P 105 Di2 Bike
Cervelo P 105 Di2 Bike Info
The Cervelo P 105 Di2 Bike brings Cervelo's P-Series triathlon platform down to a Shimano 105 Di2 build, giving a triathlete access to the same aero frame technology found on Cervelo's flagship P5 without the P5's price tag. Cervelo built the P-Series using wind tunnel work and engineering carried over from the P5, the bike that's raced at the front of World Tour time trials, then added triathlon-specific features on top: increased tire clearance, cleaner cable routing, and Cervelo's first attempt at true in-frame storage. At $6,700, this is a complete race-ready triathlon bike rather than a frameset a rider has to build out themselves.
The all-carbon frame pairs with a matching all-carbon, tapered Cervelo P fork, and the fork uses a D-shaped steerer with a round stem interface, a deliberate choice that lets a rider run whichever base bar and extensions fit their position best rather than being locked into one proprietary cockpit shape. That flexibility matters on a triathlon bike more than almost anywhere else in cycling, since aerobar position tends to change as a triathlete's fit evolves over a season or across distances.
Storage and Cockpit
This build runs a Profile Design Wing 20C aerobar on Cervelo's SuperSonic cockpit assembly, paired with a Fizik Transiro Aeris LD R5 saddle designed specifically for the forward-rotated pelvis position a triathlon bike puts a rider in. Storage comes built into the frame rather than strapped on: front and rear hydration mounts keep fluids accessible without adding drag, and a top-tube bag holds nutrition within reach during a long ride. Cervelo also increased tire and wheel clearance on this platform compared to earlier P-Series frames, which matters if a rider wants to run wider tires for comfort or rougher race surfaces.
Drivetrain and Wheels
The Shimano 105 Di2 R7150 electronic derailleurs shift through Dura-Ace R9160 bar-end shifters, a setup common on triathlon and TT bikes that keeps shift buttons within reach of the aerobars rather than requiring a rider to move their hands to a standard road shifter position. The Shimano 105 R7100 crankset runs 52/36 chainrings and comes with a 4iiii Precision GEN3+ single-sided power meter built in, giving a triathlete real wattage data without adding a separate power meter purchase. A Shimano 105 cassette in an 11-34 spread pairs with hydraulic disc brakes and Centerlock rotors for consistent stopping power regardless of weather.
Vision TC60 i23 wheels front and rear balance aero depth with everyday usability, wrapped in Vittoria Corsa N.EXT tubeless-ready tires at 700x29mm for a fast-rolling tire with enough volume for comfort over a long triathlon bike leg. The frame is available in six sizes from 48cm to 61cm, with head tube angles between 71 and 72.5 degrees and seat tube angles ranging from 75 to 79 degrees, that steep seat angle range letting a rider dial in the forward position a triathlon bike is built around.
This bike suits a triathlete who wants Cervelo's P-Series aero platform and in-frame storage without paying for Dura-Ace Di2 or SRAM's top-tier electronic groupsets. The built-in power meter crank is a real value add at this price point, since it's a component many triathletes would otherwise buy separately, and the wide seat angle range across sizes means the fit range covers most riders looking for a dedicated triathlon position rather than a converted road bike.
