There is no alternative ANT+, save for the Bontrager DuoTrap Digital Speed/Cadence Sensor, which is proprietary for the chainstay on Trek bikes. Why Trek doesn't take the internals for this and put it in a general purpose model is beyond me. If anyone wants to design a cycling gizmo sure to sell, it would be a plastic mount for the Bontrager that would work on any chainstay.



The only other way to avoid a Garmin Cadence/Speed sensor is with a power meter. The Garmin Vector pedals will report cadence, so users can get away with only a ANT+ wheel sensor, which need not be Garmin's.
