Bicycle Leather Mud Flaps

Our handcrafted, American-made leather mud flaps keep road spray off you, your bicycle, and the riders behind you. Plus, we make them in colors to match your saddle, and different shapes to suit your bicycle's style. 

Heavily infused with waxes for the toughest outdoor conditions, we use American equestrian bridle leather for these mud flaps. 

The Classic’s wing tip design channels water spray downwards, while The Road style fits more slender fenders.
