I really like the Sheebeest Pedal Pusher. I bought them here at TE on sale. Since the shorts have the same chamois I tried them and they are my favorite shorts. I have work great for me on long rides including centuries. I bought a second pair of both for this year.

PI micro sensor are good for shorter rides maybe up to 20 or 40 miles. That chamois does not work as well for me.
