After getting tired of dealing with multiple computers, I've nixed them all and I actually find riding much more enjoyable not staring at a damn computer! I just use Strava and an Apple Watch. I can get my speed/distance//time/HR with a simple glance at the watch when needed.

I am interested in the Wahoo cadence sensor. I'm not sure about others since I'm still researching it. I thought I had a solution with Strava and external sensors. It still seems possible, but tracking cadence is more useful during a ride than after anyway. I haven't looked at Wahoo's computer seriously yet.

I bought the cadence sensor because the Wahoo Kickr Core doesn't come with one. Just as well as it's more versatile to have one that isn't stuck on the bike. My main issue with the Wahoo cadence sensor was that getting into the battery compartment was a real pain in the butt.
