V5Rs Shimano Dura Ace Di2 Disc 12s

Colnago’s V5Rs is the current V-series all-round race platform, launched in 2025 as the lighter, more aero successor to the V4Rs. It sits alongside the Y1Rs, which takes the dedicated aero-bike role in the range, leaving the V5Rs to cover the broad brief of a modern WorldTour race bike that still prioritises low weight and responsiveness on climbs.

It’s aimed at riders who value a direct, race-first feel and spend a lot of time riding at tempo and above, whether that’s fast group rides, hilly races, or big mountain days. The design changes are mostly incremental rather than stylistic: updated tube shapes and manufacturing to cut mass and drag while keeping stiffness targets, with nominal 32mm tyre clearance and a threaded BSA bottom bracket anchoring the frameset’s practical side.

Fit and geometry

The V5Rs geometry leans toward current pro positions with subtle shifts that put the rider a touch more forward than before, and that shows up in how testers describe the posture over the bottom bracket. Bicycling notes that the “geometry encourages riders to sit more forward over the bottom bracket,” pairing with a chassis that rewards being driven from the hips rather than ridden passively.

Across sizes, the numbers point to a modern race silhouette: relatively low front ends for the category, reach that scales steadily, and short, consistent chainstays. Colnago’s size-specific fork-offset approach is there to keep the steering feel more consistent across the run, and reviewers’ comments fit that intent: stable when you’re carrying speed, but not necessarily the quickest feeling when you’re soft-pedalling or threading tight, low-speed turns.

The integrated CC.01 cockpit shapes fit decisions as much as the frame does. Several reviewers flagged bar width choices on test bikes as broader than they’d personally pick, and with a one-piece bar/stem, changing width or stem length is a more involved and expensive correction than on a separate setup. Seatpost offset options (15mm standard with a 0mm option) provide some room to tune fore-aft position without resorting to extreme saddle placement.

Builds

Colnago’s complete-bike range for the V5Rs is built around five headline groupset choices: Campagnolo Super Record WRL, Shimano Dura-Ace Di2, Shimano Ultegra Di2, SRAM Force eTap AXS, and SRAM Red eTap AXS. In practice, what separates the ride and ownership experience most is wheels and cockpit standardisation rather than frame differences, since the frameset and integrated CC.01 cockpit underpin every build.

At the top end, Campagnolo Super Record WRL builds come paired with Bora Ultra WTO 45 wheels, while Shimano Dura-Ace Di2 builds list multiple wheel options depending on configuration, including ENVE SES 3.4 and Shimano Dura-Ace C50, as well as Fulcrum options. Tyres are typically Pirelli P Zero Race in 28mm, with some wheel-dependent variations that include tubeless-ready versions or a more basic Pirelli P7 Sport on lower wheel specs.

Ultegra Di2 is the key step down in the ladder and is commonly the point where reviewers rode the bike on Vision SC45 wheels, which gives a good sense of the V5Rs character without the lightest, most expensive finishing kit. Across builds, gearing choices vary by groupset, and Colnago’s move to a threaded BSA bottom bracket is consistent, which matters for long-term servicing regardless of spec level.

Reviews

Most ride reports land on the V5Rs being less about a single standout sensation and more about how cleanly its priorities line up once you’re riding hard. Bicycling calls it “a cohesive whole rather than a collection of impressive numbers” (Bicycling), and that same theme shows up in longer-term ownership-style coverage, where outdoorbros describes it as “one that I don't have to think about while riding” and “second nature” after nearly a thousand miles (YouTube).

Under power, reviewers repeatedly point to a firm, efficient chassis without the brittle edge some superbikes carry. Velo says, “I found the bottom bracket area to really stand out as solid but there’s still enough flex in the rest of the bike” (Velo). On rougher surfaces, Bicycling notes that “cracked, patched concrete still comes through the front end,” but also that it “didn’t beat me up across stacked long days” (Bicycling). Cyclist similarly found “the blend of compliance and vibration seemed sensible” for a race bike (Cyclist Magazine).

Handling impressions are more nuanced. Cycling News warns “handling can feel too measured at slower speeds,” yet says it becomes reassuring when the pace rises (Cycling News). Westbrookcycles echoes that it’s “not quite as hyper agile as some of it’s competitors” while praising the way it holds a line through fast corners (Westbrookcycles).
