Speed sensor delay on rear wheel?

Hello all, 

I'm thinking about adding a speed sensor to my garmin 530 for accurate speed readings, i want to put it on the rear wheel and not at the front. Can anyone confirm is there is a lag in the speed display? I used wahoo before and the unit showed speed 5-10 seconds after I stopped which was irritating, on the front wheel it was better but not by much. Is there  much of delay with a Garmin speed sensor? When you come to a stop does it show you are stopped or does it still display speed for a few seconds?

thanks

    I've been doing fine with a Garmin speed sensor mounted on a Rohloff Speed Hub on my Co-Motion touring bike. I've had them linked with my Edge 1000 and now an Edge 1030 Plus without any issues. FWIW, I spin the rear wheel and rotate the cranks several revolutions prior to turning on the Edge so that the sensors are "live" and connect immediately. I also put on the heart rate chest strap about 15-min before riding so that the sweat makes a good connection. Hope that helps!

    HI 

    thanks for the response but is there a delay with the sensor when you come to a stop does it still show speed even tough you are not moving?

    We had blackout smoke from wildfires yesterday, and it's still bad air today. But I'll let you know ASAP.

    I just did a test of the speed sensor with the bike at rest, e.g., like it's on a spinner in the winter. I cranked it up to 14-mph for a few minutes, and it displayed a steady reading. I also tried stopping by applying the brakes, and the reading dropped to zero immediately. I also tried letting it slowly coast from 14-mph to zero gradually without any braking applied, and the reading was steadily falling as the wheel slowed. Once again, this speed sensor is mounted on a Rohloff Speedhub with a Gates belt drive. The frame is a 62-cm, and I have a 140-mm stem, so there is good separation between the speed sensor and the edge 1030 plus. I hope that helps!
