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.

INSTALLATION: Attaches with two 1/4" Chicago screws to the inside of the fender, which are placed 1" apart center-to-center. Screws and leather washer are included. You may need to drill pilot holes into the fender.
A NOTE ON OUR INVENTORY: We are only stocking Black / Classic / Sets going forward. Other mud flaps colors and styles can be made to order upon request, contact us for details.
"Leather" at Walnut means only the highest quality, full grain, un-sanded, non-stamped, natural cowhides. (For a wood analogy, it's like using a real wood board instead of particleboard or veneer.)
"Vegetable-tanned" means the hides are "tanned" (preserved for long life) using naturally-occurring oak bark and plant tannins. Just how pretty much all leather was tanned for millennia until the Industrial Revolution. (Nowadays over 90% of leather is tanned with chromium/mercury - the leather we use is the 10%.)
"American-made" means that the cow hides, which are a by-product using up the waste created by the beef industry, are from American cows, and the hides are tanned in American tanneries, which follow more stringent EPA environmental laws. (Vanishingly rare these days.)
"Uses" means we take the raw material by the hide and transform it through: cutting and shaping; hand-dying with natural oil dyes (which is like staining wood to allow the woodgrain to shine through, rather than painting it); and treating the edges into all the products you see here on our website.
Since we're using such a natural material, your product may look slightly different from the product pictures. Real, natural leather hide has unique characteristics that individually personalize each product. Each piece of leather is distinctive in its base color, grain, and markings, which may include small scars, mars, or blemishes that are a natural part of the cow's life and a sign of the high quality of the leather we use.
Walnut uses "English-style bridle leather" for a very few of our products, each of which is labeled in the Materials. Bridle leather is vegetable-tanned leather that is dyed at the tannery and infused with extra waxes and oils for more weather resistance. It's important for only a few products, such as our Bicycle Mud Flaps. The tannery dyes create a homogenous surface with a matte finish that matches the color of our hand-dyed veg-tan leather but not the lustrous natural leather grain.

Explained: Garment Leather vs Vegetable-Tanned Leather
(What is Vegetable-Tanned Leather? Learn more.)
(Shop our house-made Leather Care Conditioner.)
Our vegetable-tanned leather does great in all weather, rain or shine. It is the same kind of old-fashioned heritage leather used in equestrian gear (horse tack), so it is meant to be used outdoors and in the elements!
Being left out in a hot, direct sun is much harder on this kind of leather than wetness and rain; however, after getting wet the leather needs time to dry or else it will mildew.
Vegetable-tanned leather gains more of a luster, darkens a bit, and becomes softer with use (unlike garment leather, which fades and becomes more brittle with time and use). Un-dyed vegetable-tanned leather (our "Natural" color) will "tan" or darken in sunlight.
Vegetable-tanned leather just loves to be touched - the oils in your hands naturally condition the leather the more you use it. In fact, some of our products that are constantly handled, like our bicycle sew-on bar wraps, may rarely ever need a conditioning treatment - if they look lustrous and shiny from your hands touching and sweating on them regularly, then no need to worry.
Whether it's veg-tan or bridle leather, we recommend conditioning the leather occasionally, especially if it starts to look dry, using the care recommendations below.
If your product is starting to look dry, take the time to give it a little care with a conditioning treatment. Care for it as little as once every year or two for occasional use with good storage conditions and as much as once a quarter for heavy outdoor use in the direct sun with dry humidity.
If your leather gets dirty, clean it with diluted mild castile soap (like unscented Dr. Bronners) or unscented dishwashing liquid. Dilute the soap/liquid at least 1:10 (it should not be sudsy), and allow to fully dry before conditioning.
Keep in mind that conditioning leather usually darkens it slightly. Don't worry, this is normal. In fact, doing this several times in a row can speed up the natural darkening process that happens during aging and can also help you fine-tune the color match, if for example, you're trying to match an aged Brooks saddle.
Want to know more about leather? We wrote a FREE "Leather 101" educational course.
Want to know even more? We wrote a book! Check out the Idiot's Guide to Leather Crafts, written by Geoff and Valerie.
A: "Studiolo" is an architecture term for a small private cabinet or study room. The "lo" is a diminutive, like "little studio." And Geoff is an architecture nerd.
A: Yes, really! We know, there's a lot of "handmade washing" these days and it's diluting the meaning for real people like us. Geoff makes everything in our home, in small batches. He uses hand-tools and everything. In 2016, we upgraded our home garage from a two-car to a full-sized workshop by moving from urban Portland to the rural Oregon Coast. To see a short video of Geoff's handiwork in action and see "what handmade means to us", go to: http://vimeo.com/cineastas/walnut
A: Thank you for your support! We are a grassroots company and we appreciate all the grassroots support we've had to keep it going. Here's what can help us:
A: Great! Leather has always traditionally been an outdoor material (think equestrian gear, work boots, etc). We use the same high-quality leather used for horse gear and bridles, so it's designed to withstand the elements. Leather is an exceptionally durable material, which is why we like working with it. That said, we recommend taking care of your leather using the directions on our Leather Care page.
A: Sorry, but no! We don't recommend our products for use on motorcycles. We don't have access to a motorcycle to design them for. There's a wonderful motorcycle-specific leather craftsman in Oregon called Langlitz Leathers you might want to check out, or for your custom project, check out the website Custom Made, or there are other leathercrafters on Etsy that may be able to help out.
A: Our vegetable-tanned leather darkens naturally with age and use, but you can speed up the process with a conditioning treatment. Read more on our blog post.
A: Nothing is theft-proof these days. But read this blog post for customer ideas on how to deter theft of your leather bicycle accessories.
A: The bottom line is, you can make any bike beautiful and uniquely yours - that's the fun part! The two bicycles shown in most of our pictures are a 1980's Bianchi that we stripped completely down, had powder-coated in cream and chocolate colors, and re-built all the components from the ground up. The dark blue road bike with honey leather wraps on the handlebars and top tube is a 1970s era vintage French Detouron that we found on eBay, delivered straight from France.

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.
I am very happy with these mudguards!
