While the Tour de France GC preview at the Dauphiné grabbed headlines, bike tech enthusiasts focused on the new, unreleased bikes making their debut. Among them, a striking new aero bike from Factor pushed aerodynamic boundaries beyond existing models like the ostro VAM.

Factor has remained tight-lipped about the bike, revealing little beyond its visible features.The fork crown is sculpted and wide, while a bayonet-style fork, similar to those on the Cervélo S5 and stromm Rakett, keeps the head tube narrow. A clean cockpit with hidden cables completes the aerodynamic package.
despite its Dauphiné appearance, details remained scarce. However, the bike was spotted at Eurobike among other Factor models. Unfortunately, Factor employees remained tight-lipped, confirming only the bike’s existence.

But is the new Factor aero bike UCI legal?
Measurements taken at Eurobike revealed engaging details. New UCI tech regulations for 2026, particularly concerning fork and handlebar width, could impact the bike’s legality.

The new regulations limit internal fork width to 115 mm and handlebar width (center to center at the hoods) to 38 cm.
The Factor fork measured 114 mm, narrowly meeting the requirement. The handlebar width was also compliant at 38 cm. However,the hoods were positioned too far inward,possibly violating the new rules,though this is easily adjustable.

Given the bike’s prior UCI approval for the Dauphiné, it’s likely Factor received advance notice of the regulations. However, the short racing window raises questions about the investment versus the racing time gained.
