Redshift Sports ShockStop Suspension Stem

The ShockStop stem is designed for standard setups with a 1-1/8 inch (28.6mm) steerer tube and 31.8mm handlebar diameter. As long as your bike uses these common dimensions, it will be a direct replacement for your existing stem.

Not at all. The stem is engineered to provide vertical compliance to absorb bumps while maintaining high torsional rigidity. This means you get the comfort benefits without sacrificing the precise, snappy handling you expect from a standard stem.

Yes, the stem uses twin interchangeable elastomers that allow you to tune the stiffness to your specific weight and riding style. You can easily swap these out to find the perfect balance between comfort and responsiveness.

The ShockStop offers 1-2 centimeters of effective suspension travel. While that sounds modest, it is specifically tuned to filter out high-frequency road buzz and harsh impacts, which significantly reduces fatigue on long gravel or endurance rides.

While it is excellent for gravel and endurance road riding, it is not intended for aggressive mountain biking or technical trail use. It is optimized for smoothing out road vibrations and gravel chatter rather than handling large jumps or drops.

The ShockStop weighs 282 grams. While this is slightly heavier than a standard rigid aluminum stem, the trade-off is a substantial increase in comfort and reduced rider fatigue, which is often worth the minor weight penalty for long-distance cyclists.
