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.

I LOVE this shop! I have ordered several times from the studiolo, and I can bet I’ll be back again. These mud flaps fit my fenders perfectly which made it super easy to install them. They look beautiful and match the rest of the leather details on my bike. If you’re on the fence about buying anything from this shop, get off the fence and give them your money.
Mud Flaps on Honjo Fenders? Only Walnut will do! Quality products. Even came with leather washers for the underside of the fenders.
Very fine craftsmanship! I am very happy with these mudguards!

I ordered a set of mud flaps which arrived very quickly. They were expertly hand crafted with their looks and leather quality exceeding my expectations. I worried the leather would be on the thin side and was delighted when they arrived to find they were a nice thick, tough piece of leather and they fit perfectly in my VeloOrange Zeppelin fenders. Im happy to support small businesses especially ones that skillfully handcraft their products in the USA. Thanks Geoff and Valerie
The photos on site look nice, but it looks better when you open the package.
I have several Walnut Studiolololo bike items and the leather work is top notch. Very classy flaps to add to my old bike.
the best leather , thick snd suply , best designs - tbise tbst know know Walnut is tbe premium boutique leather goods
Absolutely beautiful flaps. Love the design, fit and finish. Very hard to come by something like this for bicycle fenders. Highly recommended! Worth every cent!
I recently purchased a Dutch made e-bike with full fenders. It’s a beautiful, well made bike But when I rode it on the ubiquitous gravel roads around my home mud and sand got sprayed onto the cooling fins of the mid-drive Bosch motor housing. Adding these attractive mud flaps not only equaled the classy look of the bicycle itself it fully solved the problem of protecting my valuable investment.
It is one of the rare USA-made bicycle mudflaps. The design makes the water fall away from the mudflap rather than stay stuck to the mudflap which is important for leather mudflaps.
A meeting of art and function, these went on in about 15 minutes on my Salsa Vaya. The hand written receipt and recyclable minimal packaging we’re all nice touches. I’ll be ordering more from Walnut.
Great leather flaps with high-quality mounting hardware that cost less that the rubber ones from Velo Orange. They were a slightly tight fit inside my fenders (for a 42mm tire; can't recall exact fender width), but could be trimmed down if needed. Width is great; kept my feet mostly dry and made the people in the pace line very happy.
A gift for my husband. Attention to detail showed right from the start...arrived in beautiful packaging! He LOVES his new mud flaps! Would order from Walnut Studio again in a heartbeat.

Functional and beautiful!
I ordered a set of mud flaps from walnut and was immediately impressed with the quality and craftsmanship of the pieces. I believe their products will stand the test of time. Walnut's mission statement is wonderful and how they conduct business is a testimony of it.
I ordered a set of mud flaps for my bike and I liked them so much I ordered a set for my wife's bike . She is going to love them as it be a great color match for her seat and hand grips . Valerie was responsive with my email questions .
Bicycle Leather Mud Flaps
Nice quality mudflap for the price. Installed easily and quickly
Great product but I didn't trust the attachment screws to keep the mud flaps on the bike. I went with a more reliable stainless steel bolt with a lock nut.
These mud flaps are exactly what I was looking for. Nice hardware and installed easily on my aluminum fenders.
After my wife telling me she was getting alot of spray riding behind me I decided some mud flaps were in order. I stumbled across the Walnut flaps and really like the look of them. I liked them so much bought one for myself and my wife. The quality of these mud flaps is very high. I would definitely recommend this product.

Super cool mud flaps. I got the skinny long one and mounted it on the front for maximum cleanliness for the bottom bracket and shoes. Works like a charm. Quality is top notch.
I had previously purchased a set of Classic Mud Flaps for my commuter bike. I like the style and how well they work. So, with my new randonneur, I didn't give a second thought to purchasing a set to outfit the new build. Stylish product. Simple installation. Clear instructions. Great customer service.
I like this flaps better than the Brooks as they aren't too thick and mount internally retaining the aesthetic appeal of the honjo fenders.
