Factor Bikes is a manufacturer of ultra-performance carbon fibre bicycles. Everything you need to know about the company can be boiled down to two words: High standards. Vires Velo is the official and exclusive retailer for Factor in the UK.


The team at Factor set the bar high for themselves in all areas. It starts with ride experience and everything that comprises. As passionate cyclists, some of them former professionals, they’re very discerning about ride quality and want the best for their customers because it’s also what they want to ride themselves. Then they look at what it takes to achieve that ride quality, and they do it. No compromises, no corners cut.

All aspects of performance – aerodynamics, lightness, handling, smoothness – are pursued relentlessly, often through dozens of prototype iterations, until targets are met. Professional men’s and women’s teams contribute to the final testing and validation, and of course showcasing the bikes on the world stage.

Superlight aero all-rounder
When the most important aspect of performance is everything – aero, lightness, comfort, handling – the OSTRO is the answer.

Ultra-lightweight climbing bike
The O2 VAM is the lightest model in Factor’s range and it comes alive when the gradient kicks up.

Lightweight road bike
Factor’s O2 is a lightweight, refined all-rounder, built for high performance, all-day comfort and exceptional value.

Factor say the OSTRO Gravel takes its ‘win everywhere’ mentality from its road racer stablemate, the OSTRO VAM, and is likewise developed to dominate its category with incredible aero, superior handling, high stiffness and low weight.

Aero road bike
The choice of sprinters, their lead-out riders, the breakaway specialists and everyone else who just loves to go fast.

Timetrial / Triathlon missile
Factor’s SLiCK is a time trial/triathlon bike drive by obsession. Obsession for speed; for boundary-pushing performance; for versatility and adjustability.

World-class TT bike
The HANZŌ time trial bike pushes right up to the limits of UCI design regulations to make it among the fastest UCI-approved TT bikes in the world.


Lightweight gravel race bike
With optimised stiffness for gravel, an ultralight 950g frame, and crisp race-focused handling, LS is a no-holds-barred gravel racer. 

Fast full suspension XC racer

This lightweight full suspension 29er elbows its way to the front of the start line with a race-oriented geometry and suspension working together.

The ultimate hardtail for fast times

The hardtail mountain bike of choice for discerning XC riders looking to maximise their speed and race times.
