BMCTimemachine Mpc.
BMC's fourth-generation Timemachine is a pure UCI time-trial frameset developed at the Impec Lab with the Tudor Pro Cycling team, which asked for a 3% cut in total rider-and-bike drag. It is built to BMC's Masterpiece (Mpc.) standard with a one-piece unpainted main frame, a wide Halo+ bayonet fork with an integrated flat cockpit, and seatstays set wider than the fork legs. Reworked to fit the UCI's 2026 rules, it is sold only as a frameset module in two sizes and in limited numbers, alongside the Speedmachine tri bike.

Our verdict
No overall score: there's no complete-bike price to rate
A no-compromise UCI time-trial frameset built for BMC's WorldTour team, with a wide Halo+ fork, an integrated cockpit and BMC's biggest aero claims yet. It is sold only as a very expensive module in two sizes with no published stack or reach, and it has no tri storage, so it suits well-funded TT specialists.

Good to know
Design
The front brake caliper mount is tilted and the rear dropouts carry 'SpeedFin' tails; the main frame is made in one piece and left unpainted to save weight.
SourceFit
BMC lists the basebar at 353 mm outside-to-outside (328 mm centre-to-centre) on both sizes, a 420 mm seatpost, and a 75.2-degree frame seat angle used with forward-offset seatposts. BMC doesn't publish stack and reach.
SourceRacing
BMC says the design had to be reworked within weeks when the UCI introduced new rules for the 2026 season, including a 120 mm limit on fork-leg stance; the final version lost some of the original drag saving.
SourceHistory
BikeRadar reported the launch on 20 February 2026 after the bike's race debut with Tudor Pro Cycling at the Volta ao Algarve. BMC calls it the fourth-generation Timemachine; the Speedmachine had taken over as BMC's tri/TT bike in 2023.
SourceVersions
BMC sells it only as a module (frame, fork with integrated cockpit and seatpost) to be built with the rider's own groupset, wheels and extensions; BikeRadar notes UCI rules require a public sale, so volumes are limited.
