Dirt-blocking buddy.

Ideally suited for fat-tire machines with its 5.5-inch width, the Portland Design Works Dave's Mud Shovel Fat Bike Fender blocks trail grime and mud from caking your bike and spraying you. Its durable plastic design uses adjustable rubber mounting straps for easy installation along the down tube. There's also a seatpost mount for extra protection from puddle splashes along your backside. And because it's riveted, you'll find that it breaks cleanly in the event of a trail mishap or serious crash to prevent damage to the fender itself. Additionally, you can trim the fender to fit smaller frames, should you opt to use this on a standard mountain bike.

  • Plastic construction with riveted, break-off design
  • Adjustable rubber mounting straps for down tube
  • Seatpost mount for rear
  • Dimensions: 5.5 x 22.5in

Not what the stellar reviews say

  • Familiarity: I've used it once or twice and have initial impressions

Yes, it covers nicely the fat tire bike.
The adjusting screw, however, came loose, so,the fender fell in the middle of the ride without me noticing it.
I used it once. ONCE.
Not recommending this one. Sad.

Perfect for the Fat Bike

  • Familiarity: I've put it through the wringer

These are super easy to install and perfect for my 5.6"+ wide fat bike tires. They've kept the mud off me and my bike.

Installation was a Snap

Super easy to install. Lots of coverage. If you are tired of wet snow or stream crossings soaking your backside here you go. The mounts are particularly gentle on the carbon frame and seat post.

Aaron, thanks for reviewing our fenders! Glad to hear they're keeping you clean and dry - they look great on your rig!
