Following the leak of spurious images that whirled about the internet last week, Colnago’s Y1Rs road bike has officially broken cover, revealing the same futuristic design that features a radical seat tube/seat stay juncture, along with a Y-shape cockpit that left on-lookers wondering about the bike’s ability to satisfy the UCI’s frame regulations.
Well, now that it’s official, with data sheet on-hand, Colnago is saying the new Y1Rs is “the most aerodynamic UCI compliant road bike in the WorldTour”, boasting it’s a claimed 28 watts faster than the Italian brand’s V4Rs at 50km/h across a full yaw sweep of -15 to +15º in bike-alone testing and 25 watts with a simulated rider.
As previously shown, the Y1Rs is equipped with Colnago’s one piece, gull-wing WYND cockpit, claiming it to be “16% stiffer in vertical and lateral stiffness” compared to other designs, while the new bayonet fork is said to reduced frontal drag by 19% compared to the V4Rs.
Elsewhere, the Y1Rs’ down tube houses an integrated bottle cage, as well as a Di2 battery.
Regarding geometry, the Y1Rs sees a slightly steeper head tube angles for smaller sizes in order to limited toe overlap, as well as a steeper effective seat angle and longer reach specifications with the aim of putting rider in a more aggressive aero position, while the Defy seat cluster is said to bolster both aerodynamics and compliance by decoupling what would otherwise be a straight line from the seat tube to the bottom bracket.
One caveat however, once the proprietary seat post is cut, there’s only 1.5cm of remaining height adjustment.
All in, Colnago says the Y1Rs tips the scales at 965 grams for the frame and 450g for the fork, neither of which will win any plaudits from the weight weenies faction. But, then again, the bike is presumably all about stiffness and aero gains.
The Y1Rs can be purchased as a frameset only for $6750, as well as a number of complete builds that span a SRAM Red AXS groupset and Vision 45 wheels for 12,300€, to a Shimano Dura-Ace Di2 equipped model that’s fitted with the same wheelset for 13,200€.
Additionally, for those wanting to make it an Italian affair, a Campagnolo Super Record Wireless equipped bike shod with Bora Ultra WTO wheels can be had for a staggering 16,500€.
