Behind Zenith is Sebastian Baldauf, a former professional cyclist and founder of the Allgäu-based brand Baldiso, which most recently which caused a stir with its sensational *The One*. The Zenith’s new carbon frame set is more of a high-performance machine than a showpiece; it is produced in small numbers and is entirely handcrafted. Each bike can be individually configured, from the choice of components and frame colour right down to the very last screw.
The carbon frame is said to weigh 860 grams in size M. Many similarly fast aero frames are significantly closer to one kilogram. A raw carbon finish without paint saves a further 100 grams in weight. Depending on the chosen build, the complete bike weighs between 6.2 and 6.9 kilograms. The bike is also said to perform very well in other disciplines. The bottom bracket stiffness is 73 N/mm and, according to the manufacturer, ensures direct power transfer. The Zedler Institute also attested that the Zenith, for a consistently aero-oriented road bike, offers a remarkably high level of comfort. Many classic aero frames score higher in this area but tend to be less comfortable.
According to the manufacturer’s own statements, Baldiso is said to have tested the Zenith in a wind tunnel in April 2026 – with a dummy, a bottle cage and a round water bottle. The manufacturer puts the result achieved at 195 watts at 45 km/h. To put this into context: in our latest TOUR aero test of UCI-compliant production bikes, the Storck Aerfast.5 Pro holds the world record at 195 watts, followed by the Stromm Rakkt (196 watts) and the Merida Reacto (197 watts).
The Zenith was designed and engineered by Simon Bühler of CarbonWorks, an engineer with many years’ experience in optimising carbon fibre structures. Baldiso opted for a highly focused development structure rather than a broad, division-of-labour-based industrial organisation. Production takes place entirely at Bike Ahead Composites in Bavaria, a manufacturer renowned within the cycling community for the surface quality and precision of its carbon manufacturing.
The frameset is available in three sizes: S, M and L; in the Carbon Raw finish, it costs 6,900 euros. Depending on the individual specifications, complete bikes range in price from 10,500 euros to 16,000 euros. Baldiso produces the Zenith in limited numbers, as each bike is entirely handcrafted.
