Description
With over 60 years of experience, and quickly gaining a reputation for consistently designing and manufacturing framesets of top-end quality, Colnago have released the C-RS Ultegra Road Bike. This full carbon monocoque bike features a straight bladed fork that is both light, responsive and durable. The aggressive geometry perfectly blends supreme comfort and precision handling, while compact seatstays and chainstays ensure snappy acceleration whether sprinting on the flat or attacking on a steep ascent. The extra width allows fitment of tyres up to 25mm.
Colnago have utilised a Press Fit bottom bracket, and the wider BB shell increases rigidity. A traditional 27.2mm diameter Colnago seatpost keeps weight to a minimum and improves comfort, damping vibrations from rough roads. The addition of an integrated seat clamp is perfectly in keeping with the clean aesthetics.
The Shimano Ultegra groupset features trickle-down technology from their top-end Dura-Ace offering and the result is lightning fast, reliable and smooth shifting, and powerful and modulated braking. Internal cable routing not only looks sleek, it creates the best possible connection between the levers and the derailleurs for improved performance.
A Shimano RS010 wheelset and Vittoria Zaffiro Pro G+ clincher tyres combine strength and durability with excellent traction and reduced rolling resistance, making them perfect for training. Finishing kit is provided by Deda, complementing the Italian designed frameset perfectly.
