Bike with Fenders on Roofrack
Sorry if this is a dumb question, but I'm about to get some fenders for my commuter, and I use the bike multimodally -- meaning, we're a one-car family, and sometimes the bike ends up on the roof of the car. So, will fenders be ok going, say, 75 mph on the highway? I'm envisioning something bad happening, a sail effect, but I often overthink things.

Only problem with fenders and a roof rack I could forsee is if you have the type that mounts via the fork. The fenders wouldn't clear if in this position
Otherwise you should be fine

they really aren't designed to take that kind of wind. Now I carry my bikes in the back of my truck or on a rear mount rack...all but one of mine have fenders now

By the way, my fenders are mounted so that they are easily removed. I zip tie them to the chainstay bridge and the seatstay bridge for a road bike and the bolts holding them to the fork and rear rack are easily removable. I can strip them off in less than 5 minutes. For the mountain bike commuter, I use clip-ons (with an extender to protect the bottom bracket/front derailer) that come off even more quickly.

No problems here. I have a 520 with 28mm tires and narrow fenders by Planet Bike. My other fendered bike is a roadified MTB with 1.25" tires. But, the fenders are for 2" tires, also Planet Bike. Plenty of wind resistance, I'm sure. Still they seem very solid.
BTW: The MTB has the type that mount using those rubber pads against the stays/forks with rubber bands holding them tight...
I miss my old Zefal fenders, but they were much thinner, and would probably not be able to take the wind.
