Smart Shape, Smart Weight
The Pulse stem features smart shapes to increase weight saving. The simple round exterior shape allows for a variable internal wall thickness. This means material is removed in the centre of the shaft saving weight. The faceplate uses a curved silhouette that helps spread shear forces around the handlebar allowing for safe use with ultralight carbon or alloy handlebars.
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 his 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.
