The Amp stem series features a 35mm bar bore to complement the Amp handlebar series. Wider bars are best paired with short stems, this is why you will only find 45 and 55mm options in this range. The Amp stem has been optimised for the extra leverage provided by wide bars and has reinforced sidewalls with extra material around the faceplate and clamp bolts to ensure great stiffness.
