Ideal for those who want to get the bar up high without sacrificing style or reach. Comes with a 25mm and a 50mm steel spacer to match. The shaft of the stem has a hole that a long compression bolt (the bolt is provided) goes through in order to keep your headset compressed. This stem will work with the Evasion (not Lite), Bombora (not Celos or ENVE), Wombat, Florida Man, Derecho, Stupid Tourist, and Scapegoat. We do not recommend using this stem on a carbon steerer tube.
