With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Colnago Y1RS Disc 2026 Carbon TT Aero Frameset in World Champ White

Season:2026Sale

Brand:Colnago

Code:COL.FS.25.Y1RSWC

Please note the image shows a complete bike build, this is the Frameset only.

Designed to defy the wind, the Colnago Y1RS is built for riders seeking maximum aerodynamic efficiency in fast racing. Its highly developed carbon frame combines reduced frontal area with increased stiffness, targeting the demands of powerful sprinters and breakaway specialists while retaining comfort for longer distances.

Compared with the V4Rs, Colnago states that the Y1RS reduces frontal area by 19%. Its aerodynamic development includes a curved down tube and the integrated CC.Y1 handlebar with WYND© technology, using a distinctive gull-wing profile designed to minimise airflow separation and improve high-speed stability.

The frame structure is claimed to provide 3.5% greater stiffness than the previous model for immediate power transfer under hard acceleration. The DEFY dual Y-shaped seatpost joint is designed to improve airflow around the seatpost while helping absorb vibration. Colnago's wind-tunnel testing also found that the Y1RS required 20 fewer watts than the V4Rs to maintain 50km/h in the tested configuration.

Features & Benefits:

  • Advanced Aerodynamic Efficiency: A 19% reduction in frontal area compared with the V4Rs, together with a curved down tube and integrated aerodynamic components, is designed to reduce drag at racing speeds.
  • Race-Ready Stiffness: A claimed 3.5% increase in frame stiffness supports efficient power transfer and responsive acceleration during powerful sprint efforts.
  • Integrated High-Speed Control: The CC.Y1 handlebar with WYND© technology uses a gull-wing design intended to manage airflow separation and improve stability without compromising stiffness.

  • Frame: Colnago Y1RS carbon aerodynamic frame
