Cutting the fenders is not a solution. That's mutilation. Just take them off.Thanks for your interest. I'll do whatever I see fit with my fenders
I finally got the rack installed and it seems to work OK with the fenders as they are. Every bus in the greater Seattle area has a rack for three bikes with a similar attachment system, I've never heard of fenders being a problem with their racks so I guess I'll take my chances. I suspect it's all CYA on Thule's part.
