V4Rs

Road.cc's Stu Kerton gives the Colnago V4Rs an 8/10 overall, praising its stunning ride performance, precise yet non-twitchy handling, impressive stiffness, and surprising comfort for a race-oriented bike, while noting the price carries a significant Colnago brand premium. The bike is tested in a size 51 with a Shimano Dura-Ace Di2 groupset, Dura-Ace C50 wheels, and Pirelli P Zero Race 28mm tyres, weighing 7,240g. The reviewer highlights the 71.8-degree head angle as unusually relaxed for a pro-level race bike, making it accessible to non-professional riders. Value is rated only 5/10, as similarly specced competitors like the Merida Reacto Team offer comparable performance at notably lower prices, though the V4Rs is broadly in line with rivals like the Pinarello Dogma F and Specialized S-Works Tarmac SL7.

BikeRadar's Ashley Quinlan provides a first-ride review of the Colnago V5Rs following a 70km loop around Lake Garda, Italy. The review characterizes the V5Rs as a considered evolutionary step over the V4Rs rather than a revolutionary redesign, noting that UAE Team Emirates XRG and UAE Team ADQ specifically asked Colnago not to make major changes. The bike is positioned as a true all-rounder to compete with rivals like the Specialized Tarmac SL8 and Pinarello Dogma F, offering marginal aerodynamic and weight improvements over its predecessor. Quinlan finds it rides remarkably similarly to the V4Rs — agile yet predictable, efficient climbing, and balanced compliance — but critiques it for not pushing tangible boundaries in an era-defining period for professional racing.

Cyclingnews associate editor Josh Croxton gives an early-verdict review of the Colnago V5Rs after ~250km of riding, finding it a capable, stiff, and competitively light race bike that balances aerodynamics with lightweight design. He praises its stability and responsiveness at high speed, and its comfortable ride quality, but flags that handling feels measured/slow at everyday speeds, the cockpit is too wide for modern standards, and cranks are longer than many riders now prefer. The tested Ultegra Di2 model is priced at €10,800 and competes with bikes like the Specialized Tarmac SL8, Factor Ostro VAM, and Trek Madone SLR, sitting at a premium but not the most expensive option in its class.

This Cyclist.co.uk article compares three premium Colnago road bikes — the Y1Rs, V5Rs, and C72 — across frameset design, geometry, weight, components, specs, pricing, and ride impressions. The V5Rs is positioned as a top-spec lightweight/aero road bike sitting between the flashier Y1Rs and the more traditional C72. The article notes that the V5Rs frameset reduces frontal profile by 13% versus its predecessor (the V4Rs), uses high modulus carbon fibre, offers a broader range of groupset options (including mid-tier choices), and is available from £9,000. A first-ride reviewer found ride comfort consistent with its race orientation but suggested wider tyres would help, and noted the handlebars felt over-wide.

This article is a long-form first-person review of the Colnago V4Rs 2026, not the Pinarello Dogma F. The Dogma F is mentioned only in passing as a competitor/comparator, receiving a few brief but pointed characterisations: it is described as slightly lighter at the frame (~770 g), slightly more aero per Pinarello's own data, more aggressively geometried, more expensive ($6,500 frameset vs $5,500), and noted for its proprietary D-shape Talon seatpost. The reviewer finds the Dogma F "more eager to turn" and gives it the edge for criteriums and short Belgian-style classics, while preferring the V4Rs for everything else. No dedicated Dogma F testing or extended analysis is provided.

This Rydecruz article provides a comprehensive 2026 review of the Colnago V4Rs, positioning it as a highly focused race bike with deep Italian heritage backed by Tadej Pogacar's 2024 Giro-Tour-Worlds triple crown win. The review covers technical specs (798g frame, 13.2W aero savings over V3Rs, 32mm tire clearance), geometry, real-world ride impressions across five scenarios, and a competitive head-to-head against rivals like the Pinarello Dogma F, Specialized Tarmac SL8, Trek Madone Gen 8, and Cervelo S5. The author is candid about trade-offs — the bike is stiff and demanding at low speeds — but awards it 9/10, calling it "among the very best you can buy" for racing. The piece also addresses the V4Rs vs. V5Rs question, concluding the V4Rs at its 2026 discounted price (~€4,800–€4,950 frameset) is "arguably the strongest value play in the Italian superbike market right now."

Cycling Weekly's Simon Smythe gives the Colnago V4Rs a strongly positive review, framing it as an uncompromising race weapon designed specifically to help Tadej Pogačar win the Tour de France. After an initial lukewarm impression at the launch in Spain (where smooth roads masked the bike's character), extended testing on rough Surrey roads reversed his verdict — he found it responsive, nimble, and at least 2kph faster on his test loop. He positions it as the fastest Colnago available, superior to the C68 for racing, and at least the equal of any pro bike on the market, while acknowledging its angular aesthetics won't suit Colnago traditionalists. At £12,599 in the tested Dura-Ace Di2 build, he notes it is actually £500 cheaper than the C68 and £1,000 below the S-Works Tarmac SL7.

BikeRadar's Ashley Quinlan gives the Colnago V4Rs Dura-Ace Di2 a 4-star rating, praising its pinpoint handling, reactive acceleration, and surprising compliance, while flagging its eye-watering price (€12,630) and aggressively pro-oriented geometry as significant barriers for most amateur riders. The review notes the bike's association with Tadej Pogačar and UAE Team Emirates, and confirms it made BikeRadar's Performance Bike of the Year 2023 shortlist. The frame weighs a claimed 798g (size 485) and is built around a CeramicSpeed SLT headset and T47 threaded bottom bracket, with the integrated CC01 cockpit claimed to be 16% more aerodynamic than the V3Rs' setup. The reviewer found the geometry demanding — long, low, and designed for pros first — and would have preferred spacers to raise the front end, but concluded that for riders who fit the position and can afford it, the V4Rs is "one of the best race bikes money can buy today."

Cyclingnews' Will Jones provides a first-ride review of the Colnago V4Rs, riding approximately 85km (plus an additional 50km the following day) during the UAE Team Emirates launch in Spain. The review is largely positive on the bike's climbing and high-speed stability, but critical of its slow handling at lower speeds, its pro-facing geometry that makes it less rewarding for amateur riders, and its steep €15,000+ price tag. Jones concludes that the V4Rs is genuinely excellent at pro speeds but unlikely to deliver sufficient value or joy to most non-professional consumers, and he would personally opt for the Colnago C68 over it.

Cyclist's review of the Colnago V4Rs, written by Sam Challis and published September 2023, gives the bike a broadly positive verdict at £11,000. The reviewer praises its well-rounded ride quality, reactive acceleration, confident handling, and holistic compliance tuning, noting it was developed primarily for UAE Team Emirates pro riders but still offers plenty to non-professional riders. Some criticism is directed at finishing details (peeling decals, awkward seatpost clamp cover, workmanlike thru-axle inserts) and the Fulcrum Wind 40 wheels and Pirelli P-Zero Race tyres are described as adequate rather than exceptional for the price point. The review highlights key engineering choices including a monocoque carbon frame, T47 bottom bracket, CeramicSpeed SLT headset, integrated CC.01 cockpit, and inclusion of a power-meter-equipped Dura-Ace crankset as standout positives.

This DMCX article by Micka provides a detailed breakdown of the Colnago V4Rs' sizes and specifications, written in March 2023 shortly after the bike's commercial release. The article covers the bike's performance claims versus its predecessor (the V3Rs), frame geometry across all seven sizes, and contextual background about the bike's development and racing pedigree with UAE Team Emirates. The author also notes this is the first Colnago designed without founder Ernesto Colnago, following the company's 2020 acquisition by Chimera Investments LLC.

This article is primarily a review of the Colnago Y1RS frameset for the Indian market, not the V4Rs. The V4Rs is mentioned only as a predecessor/baseline for comparison — the Y1RS is described as having 19% less frontal area than the V4Rs and being 20W faster at 50 km/h. The V4Rs is characterized as the "previous-generation all-rounder" that has been superseded by the V5Rs. The source provides no dedicated review or detailed analysis of the V4Rs itself; all references are comparative benchmarks used to contextualize the Y1RS's aero gains.

This Cyclingnews article is a full review of the Colnago Y1Rs, not the V4Rs. However, the V4Rs is mentioned several times as a direct comparison point — it is the predecessor that the Y1Rs was benchmarked against in aerodynamic and stiffness claims, and the reviewer also comments on the V4Rs's handling characteristics from personal experience. The article is primarily focused on the Y1Rs's design, performance, and value, with the V4Rs serving as a reference baseline.

This source is a geometry data page from GeometryGeeks.bike for the 2023 Colnago V4Rs. It presents a multi-size geometry table with raw manufacturer-sourced measurements across seven size options (420, 455, 485, 510, 530, 550, 570), covering key metrics such as reach, stack, head angle, seat angle, chainstay, wheelbase, BB drop/height, fork rake, and trail. There is no editorial commentary or review — the page is purely a data reference tool. All data is attributed directly to the manufacturer.

This Rouleur article is primarily about the newly unveiled Colnago Y1RS and its development for UAE Team Emirates. The V4RS is referenced throughout as the direct predecessor and benchmark against which the Y1RS is measured — it is not the focus of the article. Key comparative claims are made: the Y1RS is stated to be 20 watts faster than the V4RS at 50kph, 3.5% stiffer in the sprint position, and has a 19% smaller frontal area. The V4RS is described as UAE Team Emirates' "current all-rounder" and its geometry is noted as still being rooted in the C40's geometry from 1994. The article provides meaningful incidental detail about the V4RS's performance characteristics and development methodology (Real Riding Stiffness) as context for understanding the Y1RS's improvements.

This GearJunkie article is primarily about the newly launched Colnago Y1Rs, not the V4Rs. However, the V4Rs is repeatedly referenced as the direct predecessor and benchmark against which the Y1Rs is measured. The article notes that the V4Rs has won the Tour de France three times under Tadej Pogačar and that the Y1Rs delivers a 20W+ aerodynamic advantage over the V4Rs. The V4Rs is characterized as Colnago's current "normal" road race bike, serving as the baseline for all performance comparisons presented in the piece.

This YouTube video from Chile Corsa (a Colnago official retailer) directly compares the Colnago V5Rs to its predecessor, the V4Rs. The presenter characterizes the V5Rs as an evolutionary rather than revolutionary update, highlighting key improvements in weight, aerodynamics, and stiffness achieved through redesigned key areas and a different layup technology. Specific design changes covered include a slimmer head tube with a smaller top bearing, a new D-shaped steerer routing for brake hoses, a more aerodynamic seat tube and seatpost, revised seat stay attachment point, a new UDH rear dropout, a switch to BSA bottom bracket standard (saving ~40g), improved tire clearance, and two new fork rake options (47mm and 43mm) to modernize geometry across sizes. The cockpit on full builds remains the CC1, and the built-in multi-tool has been removed on the V5Rs.

This YouTube video from road.cc (or similar cycling media) compares four 2023 Tour de France bikes — the Pinarello Dogma F, Colnago V4Rs, Cervélo S5, and Specialized S-Works Tarmac SL7 — all ridden and rated by the presenter. The Dogma F is described as a balanced, heritage-rich bike that excels across disciplines, combining aero and lightweight philosophies, and is noted for its extensive color customization options. The presenter is ultimately "torn" on the Dogma F — respecting its balance and handling but preferring the look and feel of his personal SL7. The Dogma F is flagged as the most expensive frameset of the four at £5,500, with relatively few additional extras included.

This YouTube review by "Just Ride Bikes" (David) covers the Colnago V4Rs after approximately one month of riding. The reviewer is highly positive about the bike's standout stiffness and responsiveness — calling it the most responsive race bike he'd tried in a long time — and praises its handling characteristics, particularly on descents, attributing them to a slacker-than-average head angle. He notes the price is eye-watering (£13,000 as tested, £5,000 for frameset), the weight is underwhelming at 7.16 kg for the price, and the ride is firm but not punishing. He personally prefers the Colnago C68 for non-racing use, but recommends the V4Rs for anyone who wants a fast, exciting race bike.
