  • Works just as expected.
    Verified Purchase

    I purchased this to link to my Timex M229 watch. It synced right away when I activated the Speed+Cadence sensor option on the M229 and the installation on my bike was straight forward with the included instructions. After a mountain trail ride I can say that both sensors stayed in place and transmitted perfectly thanks to the included rubber pieces.
