FAQs

What is the primary benefit of the ShockStop Suspension Stem?

The primary benefit is a significant reduction in fatigue and strain caused by road shock and vibrations, leading to a smoother, more comfortable, and potentially faster ride.

How much suspension travel does the stem offer?

The ShockStop Suspension Stem provides 20mm of vertical suspension travel.

Can I adjust the suspension feel?

Yes, the stem comes with 5 swappable elastomers that allow you to customize the suspension stiffness to match your weight and riding preferences.

What handlebar and steerer tube sizes are compatible?

It is designed for standard 1-1/8" (28.6mm) steerer tubes and 31.8mm handlebars. Shims for 25.4mm and 26.0mm handlebars are available separately.

Will this stem make my bike handle poorly?

No, the design aims to provide vertical compliance without sacrificing steering stability. The suspension is optimized to absorb bumps without negatively impacting control.

How do I choose the right elastomers?

The product includes a guide that recommends elastomer combinations based on rider weight and desired ride feel (firmer or softer suspension). Experimentation may be needed to find your perfect setup.

Is the stem available in different orientations?

Yes, it is available in a +/-6 degree version and a +30 degree high-rise version, catering to different riding positions.

Troubleshooting

Stem feels too stiff or too soft

Experiment with different elastomer combinations. Softer elastomers provide more compliance, while firmer ones reduce travel and stiffness. Refer to the elastomer guide for recommendations based on rider weight.

Excessive noise or creaking

Ensure all bolts are properly torqued. Check that elastomers are correctly seated. A small amount of light grease on elastomer contact points can sometimes help, but use sparingly.

Steering feels vague or unstable

Confirm elastomer selection is appropriate for your riding style. If using very soft elastomers, consider switching to a firmer set. Ensure all mounting bolts are correctly tightened.

Difficulty installing elastomers

Ensure you are using the correct technique as shown in the product manual. Sometimes a slight twist or gentle pressure is needed. Ensure elastomers are clean and free of debris.

Pros and Cons

Pros

  • Significantly reduces fatigue on long rides and rough surfaces.
  • Improves overall riding comfort without sacrificing control.
  • Offers a customizable suspension feel through interchangeable elastomers.
  • Dampens a high percentage of shocks and vibrations.
  • Sleek design complements modern bicycle aesthetics.

Cons

  • Requires careful selection of elastomers for optimal performance.
  • Additional shims may be needed for non-standard handlebar diameters.
  • Adds a small amount of weight compared to a standard stem.
  • The initial setup might require some experimentation with elastomer choices.

Setup, Compatibility & Care

Setup:

  1. Ensure your handlebar diameter is compatible (31.8mm standard, or use appropriate shims). The steerer tube must be 1-1/8" (28.6mm).
  2. Select the appropriate elastomer pair based on your weight and desired ride feel. Lighter riders or those preferring a firmer feel should use softer elastomers (often white or grey), while heavier riders or those seeking maximum compliance should use firmer elastomers (often black).
  3. Disassemble the stem according to the included instructions, insert the chosen elastomers, and reassemble.
  4. Install the stem onto your bike's steerer tube and attach your handlebars, torquing all bolts to the manufacturer's specifications.

Compatibility:

  • Steerer Tube: 1-1/8" (28.6mm) standard.
  • Handlebar Clamp Diameter: 31.8mm standard. Shims for 25.4mm and 26.0mm handlebars are available separately.
  • Available Versions: +/-6 degree (in 90, 100, 110, 120mm lengths) and +30 degree high-rise (100mm length).

Care:

  • Clean the stem with a damp cloth and mild soap. Avoid abrasive cleaners.
  • Periodically check elastomer condition and bolt torque.
  • Store in a dry place when not in use.
