1.25-Inch MPH Axle Collar for Mychron Speed Sensors

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.
