Product details

On the surface, a stem may look simple, but under that beautiful veneer lies hours of 3D modeling, countless FEA revisions, and tons of real-world ride testing. We do all of this to make sure we have a light, stiff stem that can handle tremendous forces from every conceivable angle.
