When we set out to design the stiffest, lightest carbon stem we could we had to think outside of the normal design realm.
We present to you the O Zone, a unique 3K carbon monocoque stem with an hole in the center.
Carbon fiber allows us to make advanced shapes with no rules. This is the case with O Zone. The hole in the center reduces bulk and weight and gives a new design inspiration. To complete this jewel we equipped it with light titanium bolts.
It pairs perfectly with our carbon IPOST and WEPOST seatposts.
