Restore your trainer’s power with the Genuine Tacx S2500.04 Booster Resistance Switch.
If your Booster trainer is stuck in one gear or the lever has snapped, this official Tacx (Garmin) replacement part will get you back to your intervals. The Booster is known for its high magnetic resistance, and this 10-speed lever is the only way to accurately control that power from your handlebars.
10-Speed Manual Control: Allows you to toggle through all 10 resistance levels of the Booster's powerful magnetic brake.
Complete Replacement Kit: Includes the handlebar lever, mounting clamp, and the internal tension cable—ready for immediate installation.
Ergonomic Design: Features the signature Tacx blue rubberized thumb grip for non-slip shifting, even during the most intense, sweaty sessions.
Factory-Spec Indexing: Engineered to match the specific pull-ratio of the Booster magnet, ensuring each click corresponds to a distinct change in wattage.
Genuine Quality: This is an original Garmin/Tacx spare part, offering significantly better durability and "click feel" than generic alternatives.
Compatibility Note: Specifically designed for the Tacx Booster (T2500). Note: This is the handlebar remote assembly only. It does not include the magnetic brake unit that attaches to the rear wheel.
