The OS-115 has been around for a couple of years, but we're falling in love with it all over again thanks to FSA's bold move to offer it in white. We're awed at how much pop a white stem lends a bike -- but we're sure it does more than what you get from white bar tape or a white saddle. It sings to us.

Like the standard black OS-115, the white version has length-specific wall thickness and extensive CNC work not just for weight savings, but also for maximum durability by keeping every surface and every edge within strict tolerances. The body of the stem is made from cold forged AL2014/T6 for optimum grain alignment. And before it's painted white, the stem receives shot-peening to give it maximum fatigue life. The four bolt faceplate is made from carbon fiber and provides you with tons of handlebar security. The titanium hardware helps keeps the overall package superlight. Compatible with any 31.8mm handlebar. Available in 90-130mm lengths, in an 84° rise. 140g.
