Factor ONE Road Frameset Stirling Silver

Season : 2018

Brand : Factor

Code : Factor1FrameSil

Weight : 0KG

The new Factor ONE goes beyond aerodynamics to be the fastest aero road bike ever, not on paper or in the wind tunnel, but on the road. With the Twin Vane Evo downtube at its core, the new ONE has been designed for aerodynamic efficiency and maximum frame stiffness. Leading the peloton against the headwind, an all-out criterium or at a fast paceline through the rolling countryside, the new ONE is sure to deliver an exhilarating, fast ride.

Profiting from all the aerodynamic work to design the Factor SLiCK (time-trial/triathlon machine), Factor’s R&D team has translated that tube-shaping knowledge to road bike platform. Using the AG2R Pro-Tour approved geometry from the O2, the new ONE comes loaded with unique features.


• Twin Vane Evo downtube

• OTIS external steerer fork with wide stance legs

• OTIS Evo aero barstem

• All-internal cable routing

• Wide stance airfoil seatstays

• Clearance up to 28mm tyres

• Electronic drivetrain only

• Rim and Disc brake versions

• 7 frame sizes


Factor Twin Vane Evo Downtube:

Factor has worked tirelessly on the development of the Twin Vane Evo downtube, for more aerodynamic efficiency and maximum frame stiffness. The Twin Vane Evo takes all what we learned during the extensive aerodynamic work to design the Factor SLiCK, and has been developed through CFD in the computer and later optimised in the wind tunnel. This feature on the ONE shows an expertise in design and engineering that is unique to Factor.


Cutting Through The Wind:

The Factor ONE has been designed to push the limits beyond anything else seen in the market. Using CFD and wind tunnel data, we have perfected the aerodynamic profile of every section in combination with superior riding characteristics.


• Optimised Twin Vane Evo downtube lets the air run through while increasing the bike stiffness at the BB and headset.

• Wide stance seat stays to allow the air to flow free through, rather than around, the frame and rear wheel.

• Deep airfoil seat tube contours the rear wheel to hide it from the wind.

• The external OTIS fork features airfoil profiled, wide stance legs.


Factor OTIS:

Taking advantage of the OTIS assembly, the ONE Disc features complete internal routing. That includes the hidden front brake hose, only visible where it meets the calliper at the bottom of the fork leg.
The ONE Disc fork has been shaped using Factor’s aerodynamic know-how and CFD capabilities, reducing the volume of the crown where it blends into the headtube. At the same time, the wide stance fork legs allow the air to run through to further decrease aerodynamic resistance while increasing lateral stiffness. With the same obsession for aerodynamics and to keep things tidy, the disc brake calliper is housed in a recess of the fork leg.


Factor One OTIS Evo Barstem:

The latest evolution of the OTIS barstem, the Evo goes a step further with improved aerodynamic profile and features. The OTIS (ONE Total Integration System) barstem assembles directly to the top of the external fork, bringing outstanding stiffness while sprinting and precision during cornering. Full internal cable routing cleans up clutter from the front of the bike while still allowing for easy bar stack adjustment and disassembly for travelling.

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery Dates

Estimated Delivery Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery Dates provided on product pages.
