Look: The A-Stem is the first stem to be completely integrated into the design of the frame, in the continuation of the top tube. As well as the aesthetic impact, this integration allows us to apply our Direct Drive concept, meaning optimizing all the cockpit parameters. We achieve this by using a short head tube tapering from 1 1/2 at the bottom to 1 1/8 ?? at the top and removing the spacers. With this shorter pivot, oversized bearings and a stiffer stem, the whole cockpit is stiffer and more responsive. Available in 7 different versions (5 lengths and 2 angles), the A-Stem permits accurate adjustment of its bar height while retaining perfect aesthetic integration and optimum cockpit rigidity by avoiding the stack of spacers under the stem.
