Yes, they say any Ant+ sensor will work.
Update: While we waited for a replacement sensor to arrive, we did a couple road rides using only the GPS speed. Other than lacking a Cadence value, it worked ok and I did not notice any erratic speed readings. We typically live & die (spin tempo) by the Cadence value as a safety limiter for my stoker's knees.
