Colnago CX Zero Alloy Road Bike 2015

One of the most affordable models in Colnago's range, the Colnago CX Zero Alloy Road Bike 2015 is designed for those who appreciate a comfortable yet engaging ride. The geometry is tailored for the rider who wants a bike that offers all day comfort, whether that be in a sportive or a long training ride.

Unlike Colnago's race geometry, the CX Zero Alloy uses an endurance geometry, with higher head tube and shorter top tube to put the rider in a relaxed position on the bike. Dampening road buzz, the rear stays offer excellent vertical compliance and paired with innovative chainstays provide a silky smooth ride.

The generous frame and fork clearance leaves plenty of room for the Continental Ultra Sport II 25C tyres. These roll fast, are durable and grip exceptionally well in both the wet and dry.

Pin sharp handling is provided by the Colnago Street fork and a BB86 PressFit bottom bracket is easy to service and is hard wearing.

Stopping as fast as it accelerates, the Colnago CX Zero Alloy Road Bike 2015 uses Colnago X-Brake 3 calipers. These offer reassured braking performance and are easy to adjust.

The wide gearing options available are provided by a Shimano FC-RS500 chainset. This setup offers a 50 outer and 34 inner ring, enough gears to deal with any terrain.

Shifting fast, the Shimano 105 5800 11-speed groupset provides precise and effortless gear changes.

Finishing kit is supplied by Deda, with a RHM EL handlebar and an EL stem. The new Colnago aluminium seat post is the perfect accompaniment for the Selle Italia X1 saddle.

In a vibrant red and white colour scheme, with bold Colnago graphics, this road bike is sure to turn heads.
