An updated version of the Factor O2 was recently released, improving on the first generation by incorporating manufacturing processes used on the flagship O2 VAM. These techniques combine to make version 2 stronger, lighter and faster. One other item of note is the additional clearance for tires up to 30mm, a welcome bit of news for those of us relying on the “bigger is better” maxim. ¬†Available in both rim and disc brake versions, and for both electronic or mechanical shifting, the O2 is available now starting at $2700.00.
