Designed to be a climber, the O2 excels on the ascents. However, limiting its capabilities to only climbing would be a crime. It can sail around corners, go for long distances, and has made appearances on the podium of the Tour de France and Paris Roubaix.

The FACTOR O2 delivers a high-performance ride capable of satisfying the demands of the fastest riders in the ProTour peloton. This is the result of meticulous geometry design work, structural carbon fiber layup optimization (for best power transfer at minimum weight) and a careful choice of components. To dance up the mountains, and storm down the descents.

The FACTOR O2 features a visibly asymmetric oversized downtube that forms the backbone of the frame and is largely responsible for the highly reactive and lively nature of the bike. Using FEA software and our internal test lab bench data, we have perfected the size and profile of the downtube for every size for superior riding characteristics.

Factor Bikes sells system-integrated chassis, comprised of frame, fork, barstem, seatpost, bottom bracket, headset and a pizza box of components and accessories. Why a chassis? To control all the touch points a rider has with the road to ensure our renowned Factor ride quality.
