Factor's elegant new O2 VAM has already broken cover at this year's Tour de France, - we spotted Israel Premier Tech's Simon Clarke's bike at the race.  Today the O2 VAM is officially available with Factor describing it as the “world’s fastest climbing bike”. 

Claimed weight for the frame is just 730g for a size 54, with complete bikes from 6.2kg. Other key design features include an external seatpost, aero tube shapes and tire clearance up to 32mm. Factor’s sister company Black Inc. has also created a new 28/33 wheelset to complement the O2 VAM, which reportedly weighs just 1,146g.
