Cervelo Soloist Ultegra Di2 delivers claimed 8.6 watts of aero savings on Reserve carbon wheels
The Soloist's MY27 update is a measurable step: the claimed 8.6-watt aero improvement and 267-gram system weight reduction over the outgoing model are the kind of numbers that show up in finish times, not just spec sheets. R5-matched geometry sets a race-specific fit intent, and the one-piece Cervelo HB18 carbon cockpit eliminates stack-height variables at the stem so the position stays consistent across builds. UDH compatibility is limited to electronic drivetrains and future-proofs the dropout for SRAM Eagle Transmission. The Reserve 42/49TA asymmetric wheel pairing and Vittoria Corsa N.EXT tubeless tires are spec decisions that hold up at this price point without needing an immediate swap.
What Our Gearhead® Experts Are Saying:
"The UDH dropout is the detail I'd flag for anyone spec'ing this long-term. It locks in Transmission compatibility and means a hanger is stocked at virtually every shop, which matters when you're racing away from home."
Heads up! We do our best to keep bike specs and images current, but occasional component changes can happen without warning, and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearhead® Experts are always here to help.

The Redesign Explained
More Aero, Less Weight
The frame and fork both gained surface area for better aero shaping, not more weight. Together they shed 44g, part of the bike's 267g system-wide weight savings.
A Lighter, Faster Cockpit
The new HB18 bar and stem are molded as one piece, replacing the old two-piece setup. That's 134g lighter and 5.8 watts faster than the previous cockpit.
Narrowing The Gap To S5
The Soloist saves riders 8.6 watts at race speed versus the previous generation. That closes the gap to Cervélo's fastest bike, the S5, to just 11.8 watts, the closest yet.
Race Geometry, Every Size
Every size gets its own geometry tune, not a scaled copy of one size. It matches Cervélo's R5 down to the millimeter, so the fit and handling are proven.
Tuned For Sharper Steering
Head tube stiffness increases 10 percent for sharper, more precise steering. Bottom bracket stiffness eases slightly, a small trade-off for that extra precision up front.
