Dieser Artikel kann als Begleitartikel zum Artikel über Ledersättel gelesen werden. Ledersättel lassen sich anders als die meisten Kunststoffsättel reparieren. Ledersättel können drei verschiedene Typen von Defekten haben:

  • Der Ledersattel wird durch Missbrauch oder einen Unfall beschädigt
  • Der Unterbau kann brechen (zumeist handelt es sich um den Bruch des Sattelgestells).
  • Nieten können herausfallen oder korrodieren

Jeder dieser drei Probleme sind lösbar.

Brooks repariert Sättel in seinem Unternehmenssitz in England und es gibt aktuell (im Jahr 2022) drei weitere autorisierte Brooks Reparatur-Ansprechpartner auf der ganzen Welt. Einer davon ist RTI Sports in Koblenz, die vermutlich auch Brooks Garantiebedingungen abbilden können.


Brooks verlängert die Garantiezeit, wenn man seinen Sattel online registriert. Brooks hat ein großes Lager an lieferbaren Ersatzteilen, daher ist die Reparatur auch älterer Sattelmodelle möglich, weil das grundsätzliche Design der Brooks Sättel seit Jahrzehnten unverändert geblieben ist. Reparaturen anderer marken hängen stark davon ab, wie verfügbar die Ersatzteile sind. Am Ende dieses Artikels werden einige Firmen genannt, die Sättel reparieren können.

Ein typischer Reparaturfall ist der Ersatz einer Sattelschiene. Ein Fahrradsammler oder ein Museum könnte das Leder ersetzen wollen, wenn sie ein historisches Fahrrad instand setzen. Zwei Sättel mit unterschiedlichen Defekten können zu einen guten Sattel kombiniert werden.

Manche ältere Brooks-Sättel haben eine Eigenschaft, die es wert ist, den Aufwand das Leder zu tauschen, auf sich zu nehmen. Sie heben Ösen für die Riemen von Satteltaschen wie sie im folgenden Bild abgebildet sind. Neuere Sättel haben Aussparungen im Sattelleder für diese Riemen. Es ist sinnvoll, diese Ösen von verschlissenen Sätteln herauszulösen und wiederzuverwenden. Brooks verkauft sie auch einzeln.

Selbst durchgeführte Ledersattelreparaturen

Mit etwas heimwerklichen Geschick kann man selbst versuchen, einen Sattel zu reparieren. Manchmal ist es möglich, einen Sattel als Teilespender zu verwenden. Nachdem das Sattelgestänge eines Brooks B17 nach 30 Jahren Dauereinsatz brach, hat John Allen herausgefunden, dass ein Brooks Wright Sattel (niedrigpreisiges Modell aus den 1970er Jahren), bis auf die Oberflächenanmutung das gleiche Gestänge hatte. Er bohrte die Nieten aus dem Wright Sattel, entfernte das verzogene Leder, zog das Leder des B17 auf und hatte wieder einen perfekt funktionierenden Sattel.

To cannibalize saddles in this way, you'll need

an electric drill and bit to drill out rivets, also a centerpunch to start the drill if the rivets don't have a recess on the inside a hammer and flat-ended punch -- an old pedal spindle will do --to mushroom the inner face of rivets; and a sturdy metal surface to use as an anvil. The flat surface at the rear of a bench vise will do. If you drill out the rivets from the inside of the saddle, you are unlikely to damage either the leather or the undercarriage.

Drilling out rivets: the leather of this saddle was dried out and cracked. The undercarriage could use some cleaning up but it is sound.

You need only replace the rivets at the rear of the saddle. The metal shoe inside the nose of the saddle comes off with the top, once you have removed the rivets at the rear. Copper rivets suitable for saddle repair are available at hobby shops, online and from the saddle repairers listed in this article. After flattening large rivets at the inside, you may want to pound their edges down at the outside. An anvil may help. Keep reading for detailed isntructions.

Preferably, when cannibalizing saddles, use an undercarriage with matching locations of rivet holes. If the sheet-metal piece at the rear of both saddles is of approximately the same shape and width, you could drill new rivet holes -- in the metal, not the leather. The two saddles shown in the next picture are not compatible, because the width is too different.

The saddle on the left in the image above is a top-of-the-line Idéale Model 92. The leather is Rodée Main Selon DRebour (broken-in by hand, using the process developed by the great bicycling illustrator Daniel Rebour). Tne aluminum undercarriage cracked around the clamp-bolt hole, and the nose of the saddle would not stay up. These saddles in good shape go for big bucks now. That is all about style and their rarity: the design is flawed. Well, steel saddle rails also do break. In the photo below, I have removed the leather and inserted new rivets.

The rivet locations and the shoe in the nose of the saddle are identical to those of an Idéale Model 80 with cracked leather that I bought for $26 on eBay. This is what happens if a leather saddle is left out in the rain for years, and never re-oiled

Replacement ivets should be a tight fit into the holes in the leather, and just long enough. The scale on the ruler in the photo is in centimeters. The stem of these rivets is about 3 mm or 1/8 inch thick, and about 7 mm or 3/8 inch long. See info above about sourcing rivets.

Rivets

Bottom-of-the-line bottom, meet top-of-the-line top! Here, I have inserted rivets but not yet hammered on them. If I cared about style, I'd have repainted the undercarriage, or had it chromed. It has lasted for decades with no care and only surface rust. I figured that it will outlast the leather, and why bother.

Preferably assemble the front end of the saddle before installing the rivets or bolts at the rear of the saddle. Loosen the nose adjustment to make it easier to fit the rivets. If the nose assembly has come apart, see instructions lower down in this article.

Rivets inside the Frankensaddle

I made an anvil form an old pedal spindle.

This let me pound the rivets from both the inside and the outside of the saddle, to expand them inside, then form their heads.

Pounding rivets

TA-DA, the result! The shaping of the rivet heads could be nicer if I had a ball-peen (rounded-head) hammer and better skills, but the saddle is probably good now for as long as the leather lasts.

Assembly of the front end of a saddle is a bit of mechanical puzzle, and can be confusing. Install the most common kind of slider at the side, from inside to outside, following the arrow in the photo at the left below. The "wings" of the slider should start facing downward (with the saddle upside-down). Slide the slider around to the front, rotate it into place and insert the nose bolt, with the nut ahead of the slider as shown in the photo at the right.

Getting the nose bolt into place can be difficult if the rails are in place -- though it can sometimes pop out, and if it is adjusted as loose as possible, you may be able to pry it into place with a flat-blade screwdriver, while squeezing the top of the saddle and the rails together with your other hand to tilt the metal shoe at the nose away from the bolt.

With a sprung saddle, you may be able to avoid working with rivets, by disassembling the undercarriage and replacing the broken parts. I did this when the rails broke on a Brooks Flyer.

When the rails break, the nose bolt and slider come loose. Let's hope that you didn't lose it them the street -- or if you did, you ordered new ones.

I had the nose bolt and slider. I was able to order a new undercarriage from Brooks. This included springs, but it is easier to undo the nuts at the lower end of the old springs and re-use them, because it is possible to turn the bolts at the lower end. Keep the extra springs as spares: springs also have been known to break.

The Flyer saddle has two sets of rails.The set which is closer to the saddle top loops around the nose bolt, as shown in the photos below.

Nose assemblies may differ. The one in the image below is on a Brooks B72 4-wire saddle. It is a good idea to take a photo before disassembly, as a guide before reassembling.

Re-riveting an unsprung saddle is simple, but getting the wrench past the springs of a sprung saddle can be a bit tricky. Use a thin open-end wrench -- 1/2 inch for the Brooks saddles I've worked on. Getting a nut started is easier if you attach it to the blade of a screwdriver with a dab of grease, to reach in between the coils of a spring.

If a coil of a spring blocks a saddle's bag loop, making it hard to insert a bag strap, loosen the nuts at both top and bottom, rotate the spring, then retighten.

Sheldon strongly recommends not tightening the nose bolt. In his experience, that ruins saddles.

A leather saddle with a repaired undercarriage is as good as new -- no, better than new: it is already broken in!
