If you aren’t keen on the looks of a front fender or don’t ride in the mucky stuff enough to warrant the purchase of one then here’s a quick and cheap alternative to keep the grime out of your eyes.
Mud flaps have been popular for years among penny pinching racers. For the cost of a beat-up old inner tube and a few cable ties these go a long way towards keeping the trail from ending up all over your face.
You'll need an old inner tube, some zip ties, and scissors. Wrap the inner tube around the fork, the fork's brace. Once the distance is measure cut it and split it down the middle. Make a dovetail cut in the top. Thread the zip ties through holes in the rubber and use them to hold the mud guard in place.
