Bold claim: Cannondale’s new SuperSlice is the fastest time-trial bike they’ve ever built, even as it steps out of the shadows cast by established icons like the Specialized Shiv, Pinarello Bolide, and Giant Trinity. If you’ve followed the aero wars, you’ll know the SuperSlice has long been a rarity on UK roads and in time trials, a scarce sight even among serious enthusiasts.
The Cannondale SuperSlice Disc debuted in 2017, succeeding the rim-brake-only Slice. Initially offered in both disc and rim-brake configurations (the latter limited to pro teams), it received a second-gen refresh in 2021. The update leaned toward the SystemSix aesthetic and, for a time, remained elusive in the UK, with limited European and US allocations.
In an era where WorldTour demands pressure riders toward peak performance and aerodynamics advance at breakneck speed, the outgoing model could quickly feel outdated. Cannondale answered with a purpose-built, ultralight time-trial chassis for EF Pro Cycling. After all, 2026 is poised to be a landmark year for time-trial formats, with a team time trial opening stage at the Tour de France and an individual time trial at the Tour de France Femmes avec Zwift.
Last month, we observed a bike that looked like the new SuperSlice racing with EF Education-EasyPost at Trofeo Ses Salines. Details were scarce at the time, but we now have the essential information about Cannondale’s fastest TT bike to date.
A seamless, integrated chassis
Cannondale’s aim with the new SuperSlice was twofold: preserve steering geometry while futureproofing the platform. The result is a bike that promises greater control in the TT position thanks to a highly adjustable cockpit. It also provides clearance for up to 32mm tires and features a UDH rear dropout and a BSA threaded bottom bracket.
According to Dr. Nathan Barry, Cannondale’s Senior Design Engineer, the mission was: “Our racing bikes are about speed, so the question was how to make the new SuperSlice—and the rider—fastest possible.”
The development process involved extensive CFD modeling and wind tunnel testing to determine which shapes and tube combinations deliver the best overall system performance—considering both rider and bike as a single entity. The new SuperSlice looks markedly different from its predecessor, with sculptural, deep-section tubes, a reprofiled, narrower head tube enabled by the Delta Steerer, a beefier fork, and a more optimized rear end and seat-tube cutout.
The integrated, aero seatpost maintains the same overall dimensions as the seat tube, aiding both compliance and aerodynamics. The seat clamp allows 45mm of fore-aft movement, offering wide fit options that align with nominal effective seat-tube angles from 74 to 77 degrees.
Fans of the model will be delighted to know the iconic SuperSlice pizza graphic returns on the underside of the downtube—yes, it’s wearing a cape now.
The result of all these changes is a 10-watt yaw-weighted drag reduction at 50 km/h compared with the previous model. That’s substantial when you consider a typical EF team-issue bike weighs about 9 kg (with a 68T chainring, 90mm front wheel, and a solid rear disc).
Cannondale states that weight savings achieved in the basebar offset any gains from the fork, producing a bike that’s significantly faster without increasing total mass. Depending on how you spec it, achieving a sub-9 kg time-trial bike is within reach.
Limitations and compatibility
The new SuperSlice does not support aftermarket basebar systems, and extension compatibility is limited to components designed for Vision/FSA single-stack, mono-link TFA Evo configurations. Cannondale notes that Vision MonoRiser JS bend carbon extensions enable precise position adjustment with sliding extensions before settling on the fixed-dimension, one-piece setup.
For chainring configurations, the bike can run as a 2x setup (maximum 60/46T) or a 1x setup (maximum 64T). Cannondale cautions that larger rings may be physically possible but not recommended, and any damage from oversized chainrings would not be covered by warranty.
Unlike previous iterations, the SuperSlice isn’t solely a pure time-trial machine; it’s designed to double as a triathlon platform as well, with compatibility for Vision hydration systems.
Finish and availability
The frame comes exclusively in black, with contrasting Cannondale wordmarks and Lab71 nomenclature providing a striking appearance.
Electronic groupsets are the only option supported by the new SuperSlice.
Pricing and availability
After years of scarcity, Cannondale is pushing to make the second-generation SuperSlice accessible globally to TT runners and triathletes alike. Given the Lab71 badge and Series 0 carbon construction, it isn’t the cheapest option on the market at $6,999 / £6,995 / €6,999. And since wheelsets, saddles, and groupsets must be sourced separately, a complete build can easily exceed $12,000 / £10,000 / €12,000 depending on specifications.
If you’re chasing a race-ready setup or a fast road to the podium, the SuperSlice promises cutting-edge aerodynamics and a refined, rider-centric design that keeps pace with the newest developments in the discipline.
