Renthal's revolutionary Integra 35 stem combines high strength with ultra-low weight. The use of two independent, C-shape handlebar clamps allows the stem body material to be reduced to a minimum, while maintaining an incredibly stiff and strong structure.
The ultra-wide, 64mm handlebar clamping area increases torsional rigidity and the use of just six bolts vastly reduces overall weight. In addition, the uninterrupted clamp on the underside of the handlebar eliminates stress risers found on most other clamps, which can lead to handlebar failure.
