That, and the fact that no matter what I do, my clear glasses (and all the other lenses) fog up.
I had to ride many miles in the rain, 50 degrees, in the Czech Republic. It sucked. And I didn't even have to clean the bike; Trek Travel did.
I have had a couple of warm rides where it sprinkled/lightly rained, which was OK, but I dread how the rain will affect my braking.
I avoid it.
