Colnago's new time-trial weapon trades the TT1's aero obsession for half a kilo of weight savings — and Tadej Pogačar has already raced it.

Weight over watts: what's new

Colnago has pulled the covers off the TT2, the time-trial bike Tadej Pogačar quietly debuted at the Tour de Romandie prologue in April 2026. It replaces the TT1 with a single-minded brief: shed weight without losing stiffness or speed.

The headline figure is a 550g saving on the frame kit — frame, fork and seatpost combined — dropping a size-S kit from 2,785g to 2,240g. That's enough to build a complete bike down to the UCI 6.8 kg minimum, something the heavier TT1 struggled to reach on lumpy courses.

Per Rouleur, Colnago R&D project leader Filippo Galli breaks the saving down as roughly 300g from the frame, 137g from the fork, 90g from the seatpost and about 10g from the cockpit. The single biggest change is the fork: the TT1's distinctive bayonet steerer gives way to a conventional steerer, which on its own trims the fork from 530g to 393g.

To claw back the aerodynamics a conventional head tube would normally cost, Colnago shaped an hourglass head tube Galli says sits "at the boundary of what is possible" — around 32mm across at its narrowest, with roughly 1mm of clearance per side around the 25mm steerer.

“The aerodynamic improvement is not the core of the development of this bicycle, but to significantly reduce the weight and improve the handling.”

Why lighter, not more aero?

The answer is about where time trials are won now. Colnago argues modern stage-race TTs have become "punchy and technical", with climbs and descents that make weight "a more important factor than it has been traditionally" (BikeRadar). On a draggy flat course aero is king; on a lumpy one, grams and handling decide it.

There's a clue in Pogačar's own choices: at the 2025 Tour de France mountain time trial he opted for a stripped-down Y1Rs road-aero bike rather than the TT1. The TT2 is built so he never has to make that compromise again — Colnago even borrowed development techniques from the Y1Rs, embedding pressure sensors in a prototype frame and testing with a mannequin.

The case for and against

What's good
  • 550g lighter frame kit — finally allows a UCI-legal 6.8 kg TT build
  • Claimed as stiff as the TT1 despite the weight loss
  • 30mm tyre clearance and up to a 70T chainring suit fast, rough or 1x setups
  • New XS size plus taller M/L front ends fit more riders and modern cockpits
  • Same price as the outgoing TT1
Watch-outs
  • Aero gain is marginal (~2W) — pure flat-course specialists gain little
  • Frame-kit only at £6,499 (~R141 000) / $7,500 (~R124 000) / €7,040 (~R132 000); a full build costs far more
  • Not on sale until late September 2026
  • Hyper-thin head tube is "at the boundary of what is possible" — long-term durability unproven
  • Race-bred TT geometry is niche for everyday riders

Price, availability & where to buy

From prototype to showroom

  1. Jul 2025
    A telling compromise

    At the Tour de France mountain time trial, Pogačar rides a stripped-down Y1Rs aero bike instead of the TT1 — hinting the TT1 was too heavy for climbing TTs.

  2. Apr 2026
    Prototype breaks cover

    Pogačar debuts an unbranded TT2 prototype at the Tour de Romandie prologue.

  3. Mid 2026
    Official launch

    Colnago reveals the full TT2, confirming the 550g saving, 2W aero gain and updated geometry.

  4. Late Sep 2026
    On sale

    Frame kit available to buy at £6,499 (~R141 000) / $7,500 (~R124 000) / €7,040 (~R132 000) in four sizes (XS–L).

Lighter and simpler, or all-out aero — what should a modern TT bike chase?

Colnago TT2: your questions

How much lighter is the TT2 than the TT1? +

550g lighter as a frame kit (frame, fork and seatpost) in size S — 2,240g versus 2,785g. That lets builds reach the UCI 6.8 kg minimum weight.

Is the TT2 more aerodynamic than the TT1? +

Only marginally. Colnago claims about 2 watts of drag reduction at roughly 50 km/h. Weight and handling, not aero, were the stated priorities.

How much does the Colnago TT2 cost? +

The frame kit is £6,499 (~R141 000) / $7,500 (~R124 000) / €7,040 (~R132 000) — the same price as the TT1. Those are the launch currencies; a complete build costs considerably more.

When can I buy one? +

Frame kits are due from late September 2026, in four sizes including a brand-new XS.

What tyres and chainrings does it take? +

Clearance for 30mm tyres (up from 28mm) and up to a 70-tooth chainring, with 1x or 2x drivetrains, a UDH hanger and a BSA bottom bracket.

The bottom line

The TT2 is Colnago answering a very specific question — how do you win a time trial that climbs? — rather than chasing a headline aero number. At ~2 watts the drag story is a footnote; the 550g is the headline, and a 6.8 kg legal TT bike is a real weapon on the lumpy, technical courses Grand Tours now favour.

For the rest of us it's a £6,499 (~R141 000) frame kit aimed squarely at racers. But the engineering — a sub-400g fork and a head tube "at the boundary of what is possible" — is the kind of thing that trickles down. Shopping Colnago in South Africa today? Our price tracker is above.
