Tadej Pogačar will race a new prototype Colnago time trial bike at the prologue of the Tour de Romandie today, called the TT2.
The Italian brand says the TT2 is an evolution of the TT1 time trial bike, which Pogačar has used in support of all four of his Tour de France wins to date, with development centred primarily on weight reduction.
Colnago claims the TT2’s frameset (frame, fork and dedicated seatpost) is 550g lighter than the TT1’s in a size small, which it says mirrors a wider shift in aero bike design.
Colnago says time trial courses have become increasingly “punchy and technical” in recent years, with weight a more important factor than it has been traditionally.
Indeed, while an extreme example, Pogačar rode a stripped-down Y1Rs aero bike for the Tour de France’s mountain time trial – this contrasted with the approach of his rivals, Jonas Vingegaard and Remco Evenepoel, who rode their respective TT bikes.
The latest developments to Colnago’s time-trial platform suggest that, although Pogačar won that race, the TT1 was deemed too overweight to ride on the day.
Alongside this, Colnago says it has modified the aerodynamics, delivering a claimed two-watt improvement at 50km/h, based on a weighted average across the typical yaw angles cyclists tend to encounter.
Colnago also claims the TT2 reduces the destabilising effect of crosswinds, improving handling by limiting the need for rider corrections – factors it claims can translate to higher average speeds.
Visually, the frameset sports softer trailing edges at the head tube, a wider-arcing fork crown and a modified seatpost, while more space is left between the rear tyre and seat tube.
The new bike has also reverted to a more traditional seatstay arrangement, dropping the TT1’s horizontal bar layout that intersected with the bottle cage.
Colnago has confirmed to BikeRadar that the new bike can sport 30mm tyres with the requisite 4mm clearance, as required by ISO standard (up from the TT1’s 28mm), and can sport up to a 70-tooth chainring in a 1x setup.
For reference, the largest chainring sizes we’ve spotted on the WorldTour to date include those used by Ineos-Grenadiers’ Josh Tarling and Filippo Ganna (among a few others), typically topping out at 68 teeth.
Pogačar will ride a size small (S) at the Tour de Romandie, but Colnago says sizes XS, M and L will also be available. The smallest size is said to broaden the fit range, while the M and L frames feature taller stacks to ease position setup, according to the brand.
Availability to customers is expected from September 2026, with pricing still to be confirmed.
