I've been using a 910xt with multiple bikes. It allows you to specify which bike you're using on the device when you start. Now that I've been doing that for a couple of years, is there any way to search GC for rides according to which bike I used?
No, at least not using the bike profile you selected on the 910. Moving forward, can associate gear with activities, and eventually I'd expect to be able to search and filter based on the gear.
