To bump and seek clarification/expansion -

After several months with a 530, I'm finally getting around to setting this up for multiple bikes. I've got an Activity profile named after each bike (just two at this point, one road, one gravel). I have the data screens set up as desired for each bike/activity profile, with appropriate fields for the given sensors on each bike.

Is this as far as it goes? Now I just select/confirm the correct Activity Profile prior to a ride? Is there a way for the 530 to do this automagically based upon available sensors detected? Is there even a way to associate specific sensors with specific bikes/Activity Profiles?

What about the bike under your Gear? Do you still need to change it post-ride if you're not riding your default bike or is there some way of associating the a bike entry under Gear with an Activity Profile?

Thanks in advance!
