FSA OS-99 CSI Stem

Item #: ST248J00
Availability Please make a selection
Quantity   Out of stock.
FSA has taken their lightweight aluminum OS-99 and wrapped it in a beautiful carbon 3k weave. The resulting carbon stem is not all show with very little go. What FSA ends up with is the OS-99 CSI. A stem that is stiffer and more durable with only a slight weight penalty. Not to imply that the aluminum OS-99 is a noodle, but adding the wrap gives the stem a different character. This one works well for the powerful rider that wants a very stiff front end, or for that rider who appreciates the look of carbon in all the right places.
