    Computer Losing Connection with Speed/Cadence

    Simple question....

    I have a DuoTap speed/cadence sensor and a Garmin 800 - when I moved my bike indoors for the dreaded trainer season (Ohio) the computer would lose the cadence and then the speed single (computer seems to be working fine as it stays connected to the HRM). All are ANT+ devices.

    Replaced the battery on the Duotap....

    Any ideas on the problem?

    Thanks

    I had a friend that had that problem. Turned out it was some RFI interference from old tv he was using as entertainment while on the trainer.

    Having a duotap means you have a carbon fiber Trek frame I assume - my understanding is you are not supposed to use that on a trainer unless it's rollers?

    I have a garmin 500 and garmin gsc10 and it does the same thing from
    Time to time. I've found that in my case at least I do a reset on the speed cadence sensor then redo the search for devices from the garmin GPS. I suspect the 800 has similar functionality. I also have performed a device reset to basically wipe the device clean and start over(write down your odometer settings first though)

    I have Duotap on my Domane, and ride on a trainer with my Garmin 500. Works great. No loss of signal.

    OP, maybe some other form of signal interference from inside your house. Is your trainer setup close to something electronic?

    Disable the GPS on your Garmin and see what happens

    I second the idea that some kind of interference is causing it. I have the same dropoff on the same short section of road every time I ride that particular street. It always comes back after I'm thru that area.

    I have never seen that from Trek or any other manufacturer. Someone prove me wrong please.
