The Colnago SR9 Stem is the factory-spec component supplied with Colnago's top-tier road bikes — a detail that tells you something about where it sits in the brand's hierarchy. Built for 31.8mm handlebars and a 1-1/8" steerer, it delivers a direct, stiff connection between your hands and the front wheel. Six lengths from 90mm to 140mm give you the reach adjustment to dial in your position without reaching for an aftermarket substitute. The SR9's clean black finish integrates naturally with Colnago's aesthetic, whether you're building up a new frameset or replacing a worn stem on an existing bike. The length range covers a wide spread of rider proportions and positions — from a shorter, more upright setup to the kind of extended reach you'd run on an aggressive road build.
