สเต็มจักรยานเสือหมอบ ZIPP SERVICE COURSE ROAD STEM (SILVER) (31.8MM) (120MM) (6°)

This is the Zipp Service Course Stem. Your stem has to resist flexing during sprints and accelerations, clamp securely to the fork and handlebar, and support your weight over significant impacts. It’s a difficult job, but the Service Course stem is still able to combine strength, stiffness and reliability at a weight of only 150 grams (100mm). The Service Course SL's 3D-forged, 6061 series aluminum body paired with steel Torx bolts delivers exceptional strength-to-weight ratio while allowing for smooth lines to complement the aesthetics of modern frames.  

Features: 

•  Torx® head bolts that give precise torque readings while reducing the chance of getting stripped
