I've been using the new speed sensor on the rear hub of my single bike for the last two weeks. It's worked flawlessly with my Garmin, and it's nice not having a magnet and pickup that keep going out of line.

The new sensor should be transmitting with ANT+, but unfortunately the second computer that I sometimes use, a Pro Scio model, which is also ANT+, doesn't pick up the hub-based sensor. The other computer worked fine with the old Garmin sensor and a BBB ANT+ sensor, so I'm not sure what the problem is. As I said, when using it with the Garmin computer I've had no issues at all.
