Pogačar races a prototype Colnago TT2 at Tour de Romandie — 550g lighter than the TT1

Tadej Pogačar rolled to the start of the Tour de Romandie prologue on April 28 aboard a bike nobody had seen before in race trim: a prototype Colnago TT2. The 3.2-kilometre test in Villars-sur-Glâne, a hilly suburb of Fribourg, was the TT2's competitive debut — and Colnago confirmed the machine's existence the same day, describing it as a full redesign of the TT1 that debuted in 2022.

The most obvious departure from the TT1 is the overall silhouette. Where the TT1 had angular, aggressive tube shaping and seatstays that ran horizontally to meet an integrated bottle cage, the TT2 adopts a more flowing profile with conventionally sloping seatstays placed alongside the bottle rather than in line with it. The fork blades are noticeably shallower, and the bayonet front end has been replaced by a standard steerer inside a head tube — one with a sharper lower edge designed to redirect airflow, a shape Colnago's engineers developed drawing on aerodynamic concepts from America's Cup racing yacht bows. The frame also gains a fourth size: XS joins S, M, and L, with the M and L variants receiving a significantly taller front end to accommodate a wider range of cockpit positions.RouleurBikeRumor

Colnago's headline claim is that the TT2 frameset — frame, fork, and seatpost combined — weighs 550 grams less than the equivalent TT1 components, measured in Pogačar's size S. The brand also says the TT2 tests two watts faster at 50 km/h compared to the TT1, calculated as a weighted average across yaw angles. Full specifications have not been released; under UCI rules the bike is still registered as a prototype, and Colnago says all details will be disclosed when it approaches commercialisation. The build Pogačar raced used Shimano Dura-Ace Di2, an Enve wheelset, a Carbon-Ti 1X aero chainring, and a Fizik Aeris split-nose saddle.RouleurCyclingNewsBikeRumor

The TT2's timing matters beyond Romandie. Pogačar has two time trials at this year's Tour de France, including a stage that takes in the Côte de Larringes — around 9 km at roughly 4.3% average — where half a kilogram of frame savings could translate directly into time. Last year he famously switched to a stripped road bike for the Tour's mountain time trial rather than accept the weight penalty of his TT bike. Colnago plans to have all four UAE Team Emirates and UAE Team ADQ sizes available to riders immediately and expects consumer availability through dealers by the end of September 2026, likely too late for ITT Worlds in Montreal but in time for the following season.CyclingNewsBikeRumorRouleur
