How do you like the Lezyne? (My Wahoo has gone on the fritz again... won't update my routes. Looking for a cheaper alternative that works, sooo....)I just bought a Lezyne Super Pro cycling computer. It's water resistant but I was a little worried about taking it out for a long ride in the rain this morning. Should I be worried or will it be fine in steady rain so long as the USB port is not exposed?
