This article originally appeared on BikeRadar Factor has updated its aero frameset model for the 2018 season and see changes that focus on aerodynamic performance and stiffness. The new Factor ONE features the same unique split down tube design seen on the previous frame design, also called the ONE, as well as direct mount brakes and common aero-frame features including aero-truncated tubing, internal cable routing and lowered seatstays.ADVERTISEMENT Dubbed the 'Twin Vane Evo' down tube by Factor, the split down tube design channels air through the frame to improve aerodynamic performance, while retaining stiffness at the bottom bracket with a continuous structure from the down tube through to the chainstays. At the front end of the bike, the ONE Total Integration System (OTIS) includes Wide Stance forks and a new steerer design, as well as an integrated aero handlebar and stem combination. The Wide Stance forks are constructed from bladed forks which aim to encourage air to flow, reduce aerodynamic resistance and increase stiffness.
