Factor O2 CHPT3 - 2019, 46 cm

The 2019 Factor O2 CHPT3 is a limited-edition lightweight carbon road bike born from the collaboration between Factor Bikes and David Millar's CHPT3 brand, featuring a distinctive cream colorway with blue and red accents. Factor is a British cycling brand founded in 2009, originally as an engineering consultancy, now recognized for precision-engineered frames ridden at the World Tour level by teams including AG2R La Mondiale.

The O2 platform is Factor's pure climbing frame, tipping the scales at just 740g and built around a BBright bottom bracket for maximum stiffness-to-weight. This build runs a full mechanical Shimano Dura-Ace R9100 groupset with a 52/36 chainring combination and 170mm cranks. The Black Inc Fifty C carbon clincher wheelset pairs with Vittoria Corsa Graphene 2.0 tires in 25c for a balance of aerodynamics and grip. A CeramicSpeed headset and Black Inc cockpit components — including a 380mm handlebar and Origin8 70mm stem — round out a build that prioritizes both performance and refined aesthetics.
