The O2 VAM is an ultra-lightweight road bike designed for climbing and all-course performance when you're gunning for the top step on the podium. It combines advanced carbon technology with meticulous engineering to offer a superbly responsive and stiff ride, making it ideal for mountainous terrain and competitive racing.

Factor makes a big deal out of the O2 VAM's aero creds, which really only make sense when you realise just how quickly the bike is capable of ascending. A Mountain Goat? It's more like a Motorbike Goat. As Factor explains, with the aid of what reads like several doses of espresso: "The O2 VAM was born to climb, so it's seriously light, from just 6.4kg out-of-the-box for a 54 with Shimano Dura-Ace Di2. Few disc brake bikes can compete and none of them are aero. Crucially, that figure means the pros can line up with a bike that's still very close to the 6.8kg minimum once their pedals, cages, transponder and race number are added. One thing we all share with the pros is that when you're about to take on thousands of metres of climbing, we want the lightest bike possible. The new O2 VAM uses ultra-high-grade materials, tube shapes optimized by super-computers for stiffness-to-weight, and a new manufacturing process so advanced that we built a whole new factory."
