The CAD + SPD (BLE) profile is already supported in the current release (iOS and Android, but not Windows Phone 8.1, because M***** messed it up (no support for background location based services in WP 8.1 ...)).
CAD & SPD sensors: we recommend the Panobike for racing bikes, but for other bikes we have no specific recommendation yet.
New sensors: we've integrated oximeter support (SpO2), but still have some problems with the BLE profile.

Delayed training start (optional): OK
