Ultimate CFR Dura-Ace Di2

The Ultimate lineup is split across three carbon frame tiers: CF, CF SLX, and CFR. The entry-level CF models deliver the core handling and aesthetic of the platform at a highly accessible price, utilizing slightly heavier carbon layups and standard two-piece cockpits on the most affordable mechanical builds.

The CF SLX tier represents the sweet spot for competitive riders, shedding frame weight while upgrading to deep-section carbon wheels and electronic drivetrains from Shimano and SRAM. These mid-range builds also introduce the integrated Aerocockpit and frequently include power meters, making them race-ready out of the box.

At the top, the CFR models utilize ultra-high modulus carbon to achieve the lowest possible system weight. These premium builds are outfitted with flagship electronic groupsets and ultralight, shallow-profile wheels tailored specifically for climbing. Across the range, Canyon equips the Ultimate with a staggered tire setup or 28 mm rubber, though the frame easily accommodates wider tires for riders looking to maximize comfort and grip on rougher pavement.

Reviewers consistently praise the Ultimate for its exceptional climbing efficiency and immediate power transfer. The frame's rigidity, particularly around the bottom bracket and head tube, translates into a highly responsive ride that "accelerates willingly from the get-go" (Granfondo). Testers note that the chassis feels "reassuringly stout" (Escape Collective) during out-of-the-saddle efforts, making it an eager companion on steep gradients and tight switchbacks.

While the bike excels in the hills, its performance on flat terrain draws more nuanced feedback depending on the wheel specification. The flagship climbing builds, equipped with shallow rims, are sometimes "left a little wanting versus a more aero-optimised system" (BikeRadar) at higher cruising speeds. Conversely, models fitted with deeper wheels strike a better balance for rolling terrain.

The ride quality is generally viewed as firm but compliant enough for long days, though some testers point out that the zero-offset seatpost on the top-tier models transmits more road feedback than the setback versions found lower in the range. Additionally, while the integrated cockpit offers clever width adjustment, reviewers frequently highlight the fixed stem length as a potential frustration for dialing in the perfect fit.
