FSA OS-99 CSI UD Carbon Stem
Lightweight, durable, stiff and stylish, the FSA OS-99 CSI UD Carbon Stem is the perfect addition to your handlebar setup. Created using a 3D Forged construction process and CNC machined from AL2014. An AL2014 Alloy/Carbon faceplate holds the handlebars securely in place with four titanium bolts, keeping the weight down. Featuring a UD carbon fibre finish and dynamic FSA graphics, this really is a top of the range stem.
It’s the little details that make this stem so special. A CSI process has been used to add a UD carbon weave layer to the stem. Either a grey or red colour option means the FSA OS-99 CSI UD Carbon Stem is perfect to pair with your favourite handlebars and seatpost.
Available in a wide range of lengths, all with a 31.8 mm handlebar clamp diameter. Setup for either a +6/-6 degree angle and when installed provides a 41 mm fork clamp stack height.
Lightweight at a mere 126 grams, in 100 mm length, the FSA OS-99 CSI UD Carbon Stem is the perfect finishing touch for your road, cyclocross or time trial bike.
