Redshift Sports ShockStop Suspension Stem

The ShockStop stem is designed for bikes with a standard 1-1/8 inch (28.6mm) steerer tube and 31.8mm handlebar diameter. It is compatible with most modern road, gravel, and hybrid bikes, but you should verify your current stem's clamp size before ordering.

Not at all. The elastomer-based pivot system is designed to be firm enough that you won't notice it while pedaling out of the saddle or sprinting. It only activates when it encounters significant road chatter or impacts, so it maintains the responsive feel of a traditional stem.

Yes. The stem comes with interchangeable elastomers that allow you to fine-tune the stiffness based on your body weight and riding style. You can swap these out to make the ride feel firmer or more compliant depending on the terrain.

The ShockStop weighs 282 grams. While this is heavier than a standard aluminum stem, the trade-off is a significant reduction in fatigue and vibration, which is often worth the weight penalty for endurance and gravel riders.

Because the stem has a 6-degree angle and a 40mm stack height, it may slightly alter your handlebar position compared to your current setup. You may need to adjust your headset spacers or saddle position slightly to replicate your previous fit.
