Quick Verdict
The Colnago Y1RS is Pogačar's 2025 Tour de France and World Championships-winning aero frameset — 19% less frontal area than the V4Rs and 20W faster at 50 km/h. For Indian cyclists, it makes sense for serious amateur racers and Pogačar fans with the budget for a premium build, who ride flat fast routes (Mumbai-Pune Expressway, Yamuna Expressway, early-morning Bangalore Outer Ring Road). Skip it if you're a climber (V5Rs is 380g lighter), a first-time premium bike buyer, or you mostly ride mixed surfaces. Available now at Cobbled Climbs as a frameset for custom build. India's most comprehensive cycling retailer with 250+ brands and 15,000+ products, including authorised Colnago, Pinarello, Cervélo, Basso, and 12 India-exclusive premium partnerships.

What Is the Colnago Y1RS Frameset?
The Colnago Y1RS is the most aerodynamic road frameset Colnago has ever produced — and the bike Tadej Pogačar rode to win the 2025 Tour de France and the 2025 World Championships in Kigali. According to BikeRadar's review, the Y1RS represents Colnago's first true full-aero road bike — a significant shift for an Italian brand that previously stuck with subtle aero refinements to its all-rounder V4Rs platform. Cycling Weekly noted that the Y1RS marks Colnago's most ambitious aerodynamic project in the brand's seven decades of road racing heritage. Released in 2024, the frameset has now reached India through authorised channels at Cobbled Climbs.
The Y1RS is sold as a frameset only, not as a complete bike. This means the buyer specs their own groupset, wheels, saddle, and finishing kit — typical for premium cyclists who already have firm preferences on each component. The frameset includes the Y1RS frame, fork, headset, the new CC.Y1 WYND© integrated handlebar/stem, the dedicated aero seatpost, and integrated bottle cage mounts.
How Does the Y1RS Differ from the V4Rs and V5Rs?
Colnago's current premium road lineup has three frames serving different rider priorities. The Y1RS is the aero specialist. The V5Rs is the all-rounder lightweight climber. The V4Rs (now superseded by V5Rs) was the previous-generation all-rounder. According to CyclingNews's Y1RS review, Pogačar uses the V5Rs for mountain stages and the Y1RS for flat fast stages — and the choice is meaningful even at WorldTour level.
| Spec | Y1RS (Aero) | V5Rs (All-Rounder) | V4Rs (Predecessor) |
|---|---|---|---|
| Frame weight (raw, unpainted) | 965g | ~700g | ~750g |
| Fork weight | 450g | ~330g | ~340g |
| Frontal area (vs V4Rs) | -19% | Comparable to V4Rs | Baseline |
| Drag at 50 km/h | 20W less than V4Rs · 11W less than V5Rs | Standard | Baseline |
| Stiffness (out-of-saddle) | +3.5% vs V4Rs | Baseline class-leading | Baseline |
| Built bike weight (with race build) | ~7.5 kg | ~6.7 kg | ~7.0 kg |
| Best for | Flat fast races, sprints, breakaways, time trials | Climbing, all-round racing, GC riding | All-rounder (now superseded) |
The trade-off in plain language: the Y1RS gives you 11–20W of aerodynamic advantage at racing speeds in exchange for ~800g of additional bike weight. On flat fast routes that advantage compounds. On a 20-minute Sinhagad climb at 15–20 km/h, the weight penalty hurts more than the aero gain helps. This is why Pogačar still rides the V5Rs in mountain stages.

For sizing — and this matters more on the Y1RS than most framesets because of the integrated cockpit — see our complete bike sizing guide for Indian cyclists. The CC.Y1 handlebar is sold in three widths (370mm, 377mm, 390mm) which is narrower than typical aluminium bars on most road bikes — this matters for shoulder fit. CC-360, our AI shopping assistant, can help match your shoulder width and reach to the correct combination.
How Much Does the Y1RS Frameset Cost in India?
The Y1RS is sold internationally at $7,500 USD / €6,710. Indian retail pricing reflects manufacturer-set MRP plus applicable customs duties — for current Indian pricing, see the Y1RS product page at Cobbled Climbs or contact us via WhatsApp for build-specific quotation.
What matters more is the total build cost — buying just the frameset is the start, not the end, of the spend. A complete Y1RS build for a serious amateur racer in India typically falls in this range:
| Component | Tier | India Price Range (₹) |
|---|---|---|
| Y1RS frameset (incl. fork, headset, cockpit, seatpost) | — | ₹7,50,000–₹9,50,000 |
| Groupset — entry premium | Shimano Ultegra Di2 12-speed | ₹2,50,000–₹3,00,000 |
| Groupset — race-level | Shimano Dura-Ace Di2 / SRAM Red AXS | ₹4,50,000–₹6,00,000 |

What Groupset and Wheels Should You Build the Y1RS With?
The Y1RS is built around Colnago's WorldTour racing philosophy — every component should match. The frame is engineered for electronic groupsets (mechanical works but the routing is optimised for Di2/AXS) and deep-section aero wheels.
| Component | Recommended Pairing | Why |
|---|---|---|
| Groupset (entry premium) | Shimano Ultegra Di2 12-speed (R8170) | Best value premium groupset. 95% of Dura-Ace performance at 60% of the price. Available at Cobbled Climbs |
| Groupset (race-level) | Shimano Dura-Ace Di2 (R9270) or SRAM Red AXS | Matches the frameset's WorldTour intent. SRAM Red AXS pairs with the UDH hanger for cleanest setup |
| Wheels (entry race) | DT Swiss ARC 1400 50mm | 50mm depth matches the Y1RS aero profile. Best value race wheel under ₹2,00,000 |
| Wheels (race-level) | Shimano Dura-Ace C50, Enve SES 4.5, Campagnolo Bora Ultra WTO 60 | Wheels matter as much as the frame on an aero bike. 50–60mm depth is the sweet spot for Indian flat-route conditions and crosswind stability |
| Tyres | Continental GP5000 S TR or Vittoria Corsa Pro 28mm tubeless | The Y1RS clears 32mm — but 28mm tubeless is the race-day setup. Tubeless reduces puncture risk on Indian roads |
| Saddle | Selle Italia SLR Boost, Prologo Dimension NDR, Specialized Power | Match to your existing fit measurements — saddle is the most personal component |
| Power meter | Favero Assioma DUO pedals or Shimano Dura-Ace integrated | Required to actually use the watts an aero bike saves you. Without a power meter, the aero gains are theoretical |
For wheel selection deep-dive, see our forthcoming wheel review pieces. For pedal-based power meters: Favero Assioma is the value pick at ₹35,000–₹50,000 in India.
Where Will the Y1RS Perform Best in India?
An aero bike's advantage compounds with speed and route profile. On a flat highway at 35–45 km/h sustained, the Y1RS's 20W saving over the V4Rs is genuinely meaningful — that's 4–5% more power available for the same effort. On a 6% gradient at 15 km/h, the same 20W saving translates to nearly nothing.
| Indian Riding Context | Y1RS Performance | Better Alternative? |
|---|---|---|
| Mumbai-Pune Expressway (flat sections) | ★★★★★ Ideal — sustained 35–40 km/h, this is the bike's habitat | None — this is exactly what the Y1RS is built for |
| Yamuna Expressway (Delhi–Agra) | ★★★★★ Ideal — flat, fast, low-traffic on weekend mornings | None |
| Bangalore Outer Ring Road (5 AM–6:30 AM) | ★★★★☆ Excellent for the brief flat-fast window before traffic | None |
| Kolkata EM Bypass / NH16 (5 AM weekend rides) | ★★★★☆ Excellent on the flat sections before Salt Lake traffic builds | None |
| Ahmedabad SG Highway / SP Ring Road (early morning) | ★★★★☆ Flat, fast, low-traffic windows suit the Y1RS profile | None |
| Goa coastal highway (NH66, Panaji–Margao stretch) | ★★★★★ Ideal — smooth tarmac, flat coastal roads, and long unbroken straights make this the best Tier-3 destination in India for an aero bike; serious riders who travel to Goa for training camps bring exactly this kind of machine | None — the NH66 coastal stretch suits the Y1RS as well as any route in India |
| Pune NICMAR–Lavasa road (rolling) | ★★★★☆ Good for the flat sections, weight penalty on the Lavasa climb | V5Rs slightly better overall on this mixed terrain |
| Sinhagad Fort climb (Pune) | ★★★☆☆ Acceptable — extra weight (~800g) costs ~10–15 seconds over the climb | V5Rs is the right tool — 380g lighter, designed for climbing |
| Nandi Hills (Bangalore) | ★★★☆☆ Same — works but suboptimal for the climb | V5Rs |
| Lonavala / Khandala ghats | ★★★☆☆ Aero advantage on the descent, weight penalty on climbs | V5Rs |
| Nilgiris / Coonoor / Ooty | ★★☆☆☆ Mostly climbing terrain — wrong tool | V5Rs |
| City riding (Mumbai BKC, Delhi Aerocity, Bangalore commute) | ★★☆☆☆ Genuinely overkill — handling is too aggressive for traffic | Endurance road bike or gravel bike |
| Khardung La / high-altitude touring | ★☆☆☆☆ Wrong tool for the job | Touring or gravel bike with wider tyres |
The Y1RS is a specialist tool. If 70% of your riding is flat fast highway and group rides at race pace, it's correct. If 40%+ of your riding involves climbs above 5% gradient, the V5Rs is the smarter choice. For broader bike type selection guidance, see our road bike selection guide and our premium road bikes guide.
Who Should Buy the Y1RS — and Who Shouldn't?
| Buy the Y1RS If... | Why |
|---|---|
| You're a serious amateur racer (Indian crit racing, time trials, fast bunch starts) | The aero advantage is measurable in race results. 11W vs the V5Rs at 50 km/h is significant in a 40-minute crit |
| You ride flat fast routes 70%+ of the time (expressways, ORR, fast bunch rides) | This is the bike's exact use case. Anywhere else, you're paying for unused performance |
| You're a Pogačar fan and want the bike | Honest reason. The Y1RS is the bike that won the 2025 Tour de France and 2025 World Championships. That has emotional value worth the premium for some riders |
| You already have a climbing bike (V5Rs, Tarmac SL8, Émonda) | The Y1RS as a second bike specifically for fast routes is a coherent setup. As a one-bike solution, it's compromised |
| You build your own bikes and want to spec every component | Frameset purchase puts you in full control. Match the frame to a Dura-Ace Di2 build, your choice of wheels, your saddle preference |
| Skip the Y1RS If... | Why |
|---|---|
| This is your first or second premium road bike | You don't yet know your fit preferences well enough to commit to a proprietary cockpit. Start with a bike that has a standard handlebar/stem first |
| You're a climber — Sinhagad, Nilgiris, Khardung La regulars | The V5Rs is 380g lighter and built for climbing. Wrong tool for your terrain |
| You ride mostly mixed surfaces or commute | 32mm tyre clearance is enough for tarmac but the geometry is racing-aggressive. You'd be miserable on broken Indian road |
| Your budget is under ₹12,00,000 total build | The Y1RS only makes sense with race-grade groupset and wheels. Pairing with mid-tier components is wasteful — the V5Rs at the same total spend would be a more balanced bike |
| You ride alone, recreationally, no race intent | Aero advantages are most meaningful in race contexts. For solo recreational riding, comfort and versatility matter more than 11–20W savings |
