Colnago A1-R 105 Road Bike

The Colnago A1-R 105 Road Bike has an aluminum frame that’s at the top of its game: speed, fluidity, stability and lightness are in its DNA.Colnago placed particular attention to the orientation of tube junctions for maximum torsional rigidity without sacrificing comfort.

A 27.2mm diameter seatpost is preferred for its flexibility, comfort, and lightweight. Topping off this aluminium frameset is a fork which has a blend of alloy and cabon. The press-fit bottom bracket and semi-integrated cable routing are also prominent features on this new frame.

Shimano 105 Drivetrain

The Shimano 105 groupset is crisp, featuring Shimano?s Vivid Shift technology, with a light but positive feel all the way through the 11-speed drivetrain. The Shimano Hollowtech II chainset is stiffer and lighter than a square taper equivalent chainset, which provides greater poer through your transmission. Mounting the large diameter bearings outboard of the bottom bracket shell also provides increased stiffness and bearing life over standard cartridge units. With 50/34T compact gearing, you can tackle even the steepest climbs with confidence.

Easy Assembly

When you order a bike, one of our trained mechanics will carefully prepare and pack your bike for shipping. Upon delivery, the assembly is simple and all necessary tools are conveniently included in the box.

Depending on the delivery service and destination, bikes will either be delivered in a large or a small box. Below is a guide as to how your bike will arrive:

  • All bikes for delivery within the UK and Republic of Ireland will be delivered in a large box, except for kids? bikes and BMX bikes, which are always delivered in manufacturer’s boxes.

  • All bikes for delivery within the EU on a standard service will be delivered in a large box. If an express delivery option is chosen, your bike will be packed into a small box. Again, the exception is kids? bikes and BMX bikes, which are always delivered in manufacturer’s boxes.

  • All bikes for worldwide delivery outside the EU will be delivered in small boxes.
