OS-99: FSA OS-99 Alloy Stem
FSA’s lightweight leader, the FSA OS-99 Stem comes in as one of the best stem deals on the market. If you’re looking for a light stem that you can use without having to worry about strength or durability, the OS-99 is a great option.
Coming in at only 98 grams thanks to a 7075 T6 heat treated aluminum body and faceplate combined with titanium hardware, the FSA OS-99 Stem can hang with many more expensive stems. The OS-99 is a fairly stiff stem compared to other sub-100 gram options thanks to the 4 bolt face plate (2 bolt stems tend to twist like licorice when you crank on the bars).
Fits 31.8mm bars and 1 1/8 threadless steer tubes
+/- 6 degree rise
