Renthal integra 35 direct mount stemrenthal's challenge with the integra stem was to keep the strength, stiffness and durability of the larger 35mm diameter package at the same weight as the 31.8mm equivalent. The strength, stiffness and durability were all matched to the 31.8mm equivalent, with an average of just 1.5g added to the integra.the new integra 35 direct mount stems feature the same lightweight, 6 bolt design as the original integra ii and renthal have improved the structure of the stem.the integra 35 uses the same c shape clamping system as the apex stem range, which has been increased in size to cope with the demands of top level dh racing. The use of two independent, c shape handlebar clamps allows the stem body material to be reduced to a minimum, whilst 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.features material cnc machined 2014 aluminium body and 7075 aluminium clamps clamp diameter 35mm weight 157g 50mm x 0mmbuy renthal components from chain reaction cycles, the world's largest online bike store.
