Most riders are best served with a 6 or 7-degree positive or negative rise stem, but for those desiring the most aero position and the most power transfer, Zipp has just the stem for you: The Zipp SL Sprint.
Big and blocky, along the same vein as the Ritchey SuperLogic, the Zipp SL Sprint is not necessarily built for gram-shedding. No, it’s built to be stiff — first and foremost. With the likes of Mark Cavendish pushing this stem, you know it wastes nothing.
The guts of the SL Sprint are the same as the Exogram technology that’s used in the light and strong SRAM Red cranks. And, the results (according to Zipp) are the highest stiffness-to-weight ratio of any stem on the market.
Zipp SL Sprint Stem Features:
- UD carbon using Exogram technology
- Stainless bolts with Torx T25 heads
- Weight: 165g (100 mm)
- Rise: -12 deg
- Stack Height: 41.0mm
- Sizes: 90, 100, 110, 120, 130, 140 mm
- Price:
As mentioned, the SL Sprint Stem is not for everyone. If you are the sprinter-type who values the best aerodynamics coupled with unparalleled stiffness, this could be your stem.
