ColnagoTT1
Newer generation: TT2 (2026). Specs and test results here are for this earlier bike. What changed
Colnago's first disc-brake time trial bike, built with UAE Team Emirates and first raced at the 2022 Giro d'Italia. The monocoque frame uses the deeper blade-like tube shapes allowed by the revised UCI rules, low horizontal chainstays and a slim front end, with hydraulic hoses routed inside. It comes as a frame kit with Colnago's own basebar and a 3D-printed integrated bottle cage, in three sizes. Since mid-2026 it has been succeeded by the lighter TT2.

Our verdict
No overall score: there's no complete-bike price to rate
A WorldTour-proven time-trial frame for UCI racers who will source their own extensions and parts. Only three sizes with a fixed seat angle, bottle-only storage and a frame its lighter successor now outclasses make it a better buy at a discount or on the used market than at full frame-kit price.

Good to know
Design
Colnago says it is the brand's first time trial bike with disc brakes, which also let it hide the hoses inside the frame. Thru-axles add stiffness, and the weight penalty compared with the old K.One is small.
SourceDesign
In Colnago's TT2 white paper the TT1 frame weighs 1,279 g, the fork 530 g and the seatpost 295 g (size S, unpainted), for a 2,785 g frame kit including the cockpit and hardware.
SourceAerodynamics
The frame uses the deeper, blade-like tube and fork shapes permitted by the updated UCI guidelines, a reduced frontal area at the head tube and low, horizontal chainstays.
SourceFit
Colnago's online spec table gives a 72 mm BB drop for size S, while its downloadable geometry chart lists 70 mm for all sizes; the chart value is used here.
SourceIntegration
The bottle cage is 3D printed and moulded to the frame shape. It takes a dedicated Colnago bottle shaped for aerodynamics and grip at speed.
SourceRacing
Tadej Pogačar rode a TT1 to win the final time trial of the 2024 Tour de France in Nice. His bike was lightened with a 145 g Darimo seatpost and SRM carbon cranks.
SourceHistory
The TT1 made its race debut in the opening time trial of the 2022 Giro d'Italia with UAE Team Emirates.
SourceVersions
The TT2 replaced it in 2026. Colnago claims the new frame kit is about 550 g lighter and slightly faster.
