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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I install the MPH axle collar?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the position of the collar on the axle matter?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use this collar with other brands of speed sensors?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e This product is engineered specifically for AiM Tech Mychron speed sensors.
