Precision speed measurement starts at the axle— this 1.25-inch MPH collar clamps securely, positioning your Mychron sensor for flawless readings that inform gearing choices and driving techniques.
Compatible with standard axle diameters, it eliminates slippage, ensuring every rotation is captured accurately to log true ground speed. In kart racing, where trap speeds decide overtakes, reliable MPH data helps you select sprockets that balance acceleration with straight-line pace.
- Fits 1.25" axles perfectly, with easy installation via set screws.
- Enhances data acquisition by stabilizing sensor proximity to the wheel hub.
- Supports track organization with a low-profile design that doesn't interfere with hubs.
Use insights from this setup (SKU: MC125) to compare laps, spotting where speed drops in corners for chassis tweaks. It's a small piece with big impact, turning raw velocity numbers into strategies that propel you faster overall.
Racers love how it simplifies speed logging, freeing mental bandwidth for aggressive lines rather than guesswork.
Frequently Asked Questions
Q: How do I know if this 1.25-inch collar is the right size for my kart?
A: This collar is specifically designed for 1.25-inch (approx. 32mm) rear axles. Please measure your axle diameter with a caliper before purchasing to ensure a secure fit, as using the wrong size will result in slippage and inaccurate speed readings.
Q: How do I install the MPH axle collar?
A: Installation is straightforward. Simply slide the collar onto your rear axle, position it so the magnet aligns correctly with your Mychron speed sensor, and tighten the integrated set screws evenly to lock it in place.
Q: Does the position of the collar on the axle matter?
A: Yes. For the most accurate data acquisition, the collar must be positioned so that the magnet passes directly in front of the sensor at a consistent, close proximity without making physical contact. Ensure the collar is tightened securely so it does not shift during high-speed cornering.
Q: Can I use this collar with other brands of speed sensors?
A: This product is engineered specifically for AiM Tech Mychron speed sensors. While it may physically fit other axles, the magnet placement is optimized for the Mychron sensor's detection range.
Q: How do I maintain the collar during the race season?
A: Periodically check the set screws to ensure they haven't vibrated loose due to track conditions. Keep the magnet surface clean of metallic debris or grease to ensure the sensor receives a clear signal every rotation.
