Bolt Zipp's Service Course SL Stem to the front of your bike and watch how it resists flexing during sprints and boosts steering precision thanks to its outstanding stiffness. It's made from 3D-forged 7075 aluminum with titanium bolts for an exceptional strength-to-weight ratio, serious rigidity and comforting reliability at a weight of only 120 grams.
Stem angle is one of the factors that determines handlebar height. A listed angle of 0 degrees actually provides a rise of 16-20 degrees, depending on the bike's head-tube angle. Flexible, athletic riders prefer lower-rise stems, while recreational riders usually favor higher-rise stems.
