Who makes fenders for the Pugsley?
None of the major fender players currently offer a fender that completely covers a 3.7" or 3.8" tire. There are some folks who make wood fenders. they'll do a custom set for you for some number of dollars. These are cool. Also Portland Design Works or PDW makes a fender called the Mud Shovel (a larger version of their Origami Fender), they offer partial coverage and are in the mountain bike clip on style. These are also cool. You can also DIY some fenders out of some corrugated plastic (look at your local craft or hobby shop) and some bits of fender hardware. Good luck. We believe in you.
