Make you faster
Zipp is back, and they mean business with an all new cosmetic look that screams speed. Zipp parts all serve to complete one purpose: make you faster. They design these components to help you achieve your optimal position on the bike for efficiency and speed.

No-flex sprints
Zipp’s Service Course SL stem, crafted from 7075 aluminium, features a shape that’s strong and light weight, resulting in a best-in-class 1.85g per newton meter of stiffness. That results in no-flex sprints and accelerations.

Variety is key
To meet every rider’s fit needs, the stem is available in ±6° and ±17° angles and seven lengths from 70 to 130mm as well as a 140 and 150mm lengths for the ±6° stem only. This stem is a favorite of Zipp ambassadors and pro athletes.
