I put SKS Commuter Fenders on my Trek 1200 this past weekend:



I posted my first impressions on Commute By Bike.

The one thing many commenters have bewailed is that the fenders don't go down "far enough" on the back. Far enough is relative, though. They keep all the grime off of me, and people who complain about the fender's length in the back believe that a fender's purpose is also to keep from throwing stuff onto the person behind you. I'm slow and no one's ever behind me, so this was a well-spent $32 in my opinion. I don't think I could find any that scrape the pavement behind my bike for that price.
