Syncros blended the best of two materials when designing its FL1. 0 Carbon Stem, which features carbon and aluminum in its construction for a mix of efficiency and lightness with affordability. Starting with treated 7075 aluminum for strength and durability in the initial shape, Syncros then reinforced the stem with unidirectional carbon fiber to add stiffness without weight. The result is a sleek, race ready stem weighing in at a claimed 125g that, according to Syncros, roadies and XC trail riders alike can both take advantage of. The broadened, four bolt faceplate was designed to optimize the distribution of weight and better manage stress compared to more compact, two bolt designs. It also doesn't require as much clamping force to be secured, so there's less chance of crushing your carbon bars.
