i have a trek ach computer (cadence and hr); the computer (wireless) needs to identify individually the inputs coming from the sensors as part of the setup process. when i first used it i got speed and cadence paired easily but hr just refused over and over again until one time it responded.
i've got the computre on a second bikle; the speed paired easily but the cadence has consistently refused. it seems a bit unpredictable does anyone else have trouble?
