FAQs

Will this fit a standard round seatpost?

No, this insert is specifically molded for Kamm and D-shaped aerodynamic seatposts.

Can I use this with lights other than the TraceR?

This bracket system is designed specifically for Exposure TraceR models.

Will the silicone damage my carbon seatpost?

No, the silicone is designed to be protective and prevents direct metal-on-carbon contact.

Do I need any tools to install this?

Typically, no tools are required as it uses the existing clamping mechanism of the Boost-R bracket.

Is this compatible with Boost-R ReAKT models?

Yes, it is fully compatible with both Boost-R DB and Boost-R ReAKT models.

Troubleshooting

The mount feels loose or slips during the ride.

Ensure the seatpost surface is completely clean and dry before installation. Check that the bracket tension is tightened correctly over the insert.

Difficulty fitting the bracket over the insert.

Ensure the silicone insert is perfectly centered on the seatpost before attempting to snap the bracket into position.

Pros and Cons

Pros

  • Ensures secure fit on specialized aero seatposts
  • Prevents light movement during high-vibration riding
  • Soft silicone surface protects carbon fiber finishes
  • Easy installation without the need for specialized tools

Cons

  • Not compatible with standard round seatposts
  • Specific to TraceR rear light ecosystem
  • Must be used in conjunction with the Boost-R bracket

Setup, Compatibility & Care

To install, first clean the rear surface of your seatpost to ensure no grit or grease is present. Place the silicone insert against the post so the contours align perfectly. Attach the Boost-R bracket over the insert and secure it according to the light's mounting hardware instructions. This accessory is compatible with the Boost-R DB and Boost-R ReAKT models. For care, periodically remove the bracket to clean any accumulated road dust from the silicone face with a mild soap and water solution to maintain its gripping properties.
