Colnago Y1RS Dura-Ace Di2

The Colnago Y1RS Dura-Ace Di2, model 2026, is a road bike for your road rides, with a Shimano 12-speed build. It is offered in sizes XS, S, M, L and XL: the L version is available only as a frame to build up, a point to consider when choosing.

Created to challenge the wind, the Y1RS requires 20 fewer watts than the V4Rs at 50 km/h in wind tunnel tests, according to Colnago.

• Shimano drivetrain: A Dura-Ace FD-R9250 front derailleur, Shadow RD-R9250 rear derailleur and CN-M9100 chain make up the drivetrain.
• Disc brakes: Braking is provided by Dura-Ace hydraulically operated disc brakes.
• Vision SC45 wheels: The wheelset chosen for this build is the Vision SC45.
• Carbon components: The Colnago fork, CC.Y1 integrated handlebar and seatpost are made from carbon.
• BSA bottom bracket: The bottom bracket uses the BSA standard with a threaded mounting system.
• Saddle subject to availability: Scratch M5 Nack 140 Hard Black or Selle Italia SLR Boost Superflow Carbon Rail, depending on availability.

Choose it if you are looking for a Colnago road bike with a build combining Shimano and Vision components, considering the size that suits you.
