Sorry, I know nothing about fenders except the plastic Planet Bike fenders I had on my old commuting bike seemed kind of flimsy compared to the ones I've got now. I don't know if the easy-on/off fenders work well.
But they're absolutely essential if you're going to commute in the rain!
I wish I'd seen those before I ordered fenders from REI!
I'd rather be swimming...biking...running...and eating cheesecake...
