We test the Colnago K.Zero triathlon bike in our four ride review.


First Ride

A bike as specific as the K.Zero isn’t one to just hop on and ride; the brakes in particular demand watchmaker-like attention to optimise the set-up and performance, but once dialed in, they needed no more attention than conventional callipers. The extensions can be adjusted for height, and to one of four lengths – with different integrated stem lengths available – but the angle of the base bars can’t be altered.

Fast Ride

With a frame proven at the highest level of road time trialling, speed was always going to be on the menu. Vision’s Metron trigger bar-end shifters took a little time to adjust to, but as we relaxed into position, our speed rose rapidly, the Continental Competition tubular-shod Metron 90 wheels sustaining a satisfyingly rapid velocity with minimal extra effort. They did become a hindrance in stiff breezes though.

Hilly Ride

At 8.73kg for our medium build, the Colnago is no featherweight, but the laterally stiff frame is equally good at sprinting out of corners or heaving up gradients, the stiff 90mm hoops converting energy into uphill motion efficiently. The K.Zero is surprisingly nimble, exhibiting predictable handling that cultivates cornering confidence, and the hidden V-brakes never want for stopping power from speed.

Long Ride

Over long rides, the character of the K.Zero really shines through. It exploits the middle ground between twitchy speed and handling compliance in a hugely accessible manner, offering great reactivity to power inputs and easy-to-live-with performance. The Metron groupset provides incredibly snappy gear changes and the comfy Vision saddle helped
ease us through the longest of efforts.
