Got new fenders put on my commute bike. I'm looking forward to using these.

They are all aluminum, subtle gray anodized, fit tight and slim over 700C 23mm tires, very full coverage, long mudflaps, and mount on an old racer frame with tight clearances and no eyelets. PDW make. I have been using RaceBlades all winter, and am hoping these keep my bike cleaner. They look more integrated, less stuck on.

Do you run fenders on you bike? Do you like them, or just tolerate them as a necessary evil?
