Zipp Service Course SL SS bar/SL stem - in brief review

Aluminium road bike cockpit

BikeRadar score4/5

The Service Course SL SS shape is both shorter than most and much shallower too. The angled flats on the drop curve give a great handhold, comfortable and well placed for sprinting.

It works well with the angled radius that transitions from top to drop, which also gives ideal wrist clearance. For an all-aluminium affair, the SL SS is comfortable, and though stiff enough for steering, does a great job of reducing road buzz.

The slim alloy stem uses high quality titanium bolts that are Torx-headed, so you’ll need a Torx bit for your torque wrench or a Torx key set.
