Fenders Gilles BERTHOUD My best fenders are made by Gilles BERTHOUD, in France. But they may not be for everybody. The stainless steel versions take a bit of work to install. But, once installed, they are very rugged, and give the best protection against spray from the tires, particularly if you use their optional leather mud flap in front. They also make super lightweight carbon fiber fenders for brevet bikes. The Berthoud fenders now come pre-drilled for the struts. You will have to drill holes to mount the mud flaps, if you get mud flaps. There are two types of Berthoud fenders, stainless steel, and carbon fiber. Both types use lightweight aluminum struts. The carbon fiber fenders are made in only one size; 700c x 25mm. They are very light. Since most tires labeled 700x28 are actually about 25mm wide, these can be used with most 700x28mm tires, making them ideal for brevet or randoneuring bikes, like the Rivendell Rambouillet. The mud flaps can't be used on the carbon fiber fenders. The stainless fenders are a bit heavier, a lot less expensive, and come in a variety of sizes; 700c x 40mm, 700c x 50mm, 700 x 60mm, 650 x 40mm, 650 x 50mm, 26" x 40mm, 26" x 50mm and 26 x 60mm. The carbon fenders are sold as a complete set. The stainless fenders are sold "a la carte". The optional leather mud flap is only to be used with the stainless fenders. People have been asking if the mud flap is suitable for use with Esge/SKS fenders. I don't recommend it, since those fenders aren't as tough as the stainless Berthoud fenders, and the wind acting on the flap may cause the SKS fenders to crack. Also, Berthoud has teamed up with SKS to make several very light weight fender sets. The fenders are the same plastic - aluminum - plastic sandwich as used in the SKS branded fenders. But unlike the SKS, which use heavy steel struts, these use berthoud's light weight aluminum struts. So it's a very light combination, the best of both brands so to speak, if weight is paramount. I have three sizes, all for 700c; 35mm, 42mm and 50mm, in stock. The color is the same silver as in the SKS fenders. They all have a nice rounded shape, just like the Berthoud stainless fenders. The Dreaded Fine Print Of course, any fender will eventually crack due to the constant flexing that happens while riding. While I have yet to see a report of a carbon fiber fender breaking, it won't surprise me to see one fail eventually. The Berthoud stainless fenders are clearly the most rugged full coverage fender available that don't weigh as much as a bicycle. We get very few reports of cracks with these. But we do get some. And a crack is not considered a defect and is not covered by any warrantee. It's like a tire wearing out. Some tires last longer than others, and some fenders last longer than others. Berthoud stainless fenders are like very durable touring tires. They'll last a long time. But eventually, they will wear out. $ 190.00

The metal is rolled to the inside to eliminate the sharp edge, make the fender stiffer, and increase the life of the fender before it finally cracks and needs to be replaced. This makes the inside width of the fender about 9mm narrower than the stated width. So, you should always use a fender that is at least 10mm wider than the width of your tire, and probably more like 15mm wider, depending on how much vertical clearance you have over the tire in your frame. 60mm wide stainless fenders are now in stock!
Add an oil impregnated leather mud flap for $ 14.00 The leather mud flap can only be used on the stainless steel fenders. It is not to be used on the carbon fiber fenders. Nor is it suitable for use on other brands of fenders such as Esge/SKS. So, if you want the mud flap, you'll just have to get the fenders, heh, heh, heh. The mud flap really makes the Berthoud stainless fenders special. The flap eliminates the spray that would otherwise be directed at your feet from the front tire, whenever the wheel is turned in a corner. It makes a big difference in how dry your feet remain during a ride.
Parts for Berthoud stainless steel fenders are available. I stock the aluminum struts, all the nuts and bolts, as well as the fenders themselves without hardware. So if anything should be damaged in a crash, or fail from fatigue, you can buy what you need to make repairs. See the Berthoud Parts page. For installing Berthoud fenders, go here. The main Berthoud page is here. Berthoud also sells plastic/aluminum sandwich fenders. The fender sections are made for Berthoud by SKS, see below for SKS brand fenders. But unlike the SKS fenders which have steel struts, Berthoud uses his aluminum struts to save quite a bit of weight. It does seem a bit silly to have an extremely light fender but then use heavy steel struts to support them. Aluminum struts are still much stronger than the plastic/aluminum fender, and weigh next to nothing. These are all in the light silver finish we're all used to seeing in the SKS fenders. Dark grey or black is not an option. I have three sizes, 35mm, 42mm and 50mm, all in stock. Subtract 8mm from the fender width to know the largest size tire you should use with these fenders. You can always use a smaller tire, of course. All three sizes are the same price: $ 50.00 The fender hardware is virtually identical to the hardware for the other Berthoud fenders. It's the exact same set of bolts and plastic "P" clamp to attach the fender struts to the frame's dropouts. And the connections between the struts and the fenders are the same. What's different is the connection between the front fender and the fork crown. That uses the more traditional system used by SKS, an "L" bracket riveted to the fender with a hole to be fixed to the crown via the brake bolt. If you have caliper brakes with Allen fittings, you'll want to order the Berthoud brake bolts. See below. We have special nuts that replace the allen nuts which hold most modern caliper brakes on frames these days. These nut are special in that they have a 10mm head and a 5mm thread into which you can screw a 5mm bolt, like the button head bolt you see below. This makes it possible to mount fenders to the rear of your fork crown, where most fenders are designed to mount.
The round head allen screw bolts into the special replacement nut for your brakes. It's an ingenious solution to the problem of mounting fenders to bikes with allen nutted brakes. And it allows you to remove the fenders without loosening the attachment of your brakes. I have these available in four different lengths. 9mm and 13mm, Price: $ 4.50 22mm, Price: $ 6.50 30mm, Price: $ 7.50 The dimensions, 9mm through 30mm, are for the part of the nut that you can't see, the part inside the fork crown. Different lengths are needed for different fork crowns, and for different applications. For example, if you are mounting not only fenders, but also a Busch & Müller Ixon headlight to the fork crown, that Ixon mount is 10mm thick, and so your caliper brake will then be another 10mm further forward of the fork crown, and the rear nut will have to be another 10mm in length, over and above whatever length it needed to be without the Ixon mount.
See the installation page for instructions on installing Berthoud fenders. Berthoud Composite Fenders These are the fenders using Berthoud's light weight aluminum struts and SKS composite fender material. The fenders themselves are not the same as what SKS sells, they are specific to Berthoud, but the composite material, plastic on the outside with aluminum in the middle, is the same as SKS sells under their own brand. These are only made for 700c or 622 tires. There have the same silver metallic finish as the SKS fenders below. But they weigh a lot less, because instead of using steel struts, they use light weight aluminum struts. Why would you need steel struts to support plastic and aluminum composite fenders? Seems a bit excessive, don't you think? Composite 700x35 fenders: $ 50.00 Composite 700x42 fenders: $ 50.00 Composite 700x50 fenders: $ 50.00
Esge/SKS Esge fenders are now sold under the name SKS. I don't know why, and I don't particularly care. They're great fenders. They have a thick core of aluminum, and that core is sandwiched between two layers of plastic. The plastic helps keep the aluminum from bending, and the aluminum helps keep the plastic from splitting. They last a long time, are very hard to break, and they don't even look too bad. In my experience, they are the next most durable fender after the Berthoud stainless fenders, above. The front fender has a break-away attachment at the dropouts to help prevent the wheel from locking up should something get caught between the fender and the tire. They aren't as durable as the Berthoud stainless or carbon fenders, but they cost less and are easier to install. And other than the Berthoud fenders, I don't know of anything that works as well and lasts as long as these.
Esge fenders are also tough enough that you can mount a taillight on them. Just drill two 5mm holes one above the other, 20mm apart, on the rear fender, and you can mount a Spanninga battery powered taillight, or a Seculite Plus taillight, powered by a generator such as a Schmidt hub generator, or a Dymotec tire sidewall generator. Be careful to place the light so that the beam is directed at driver's eye height.
I also have the new SKS Commuter fenders in stock. Pictures and pricing soon.
