I am sulking and pouting in my room near Zurich at the moment because it's raining. Not raining so hard you couldn't have a good ride with a fendered bike but hard enough that riding without fenders would be miserable.
When I get an S&S bike it will definitely have eyelets and clearance for fenders.
I know we've been over this a million times on this forum but today is a perfect example of why they're totally useful. Light rain but wet roads. With fenders maybe get a bit wet but it's manageable. Without them and it's like riding rollers in a cold shower.
That is all.
