I look forward to hearing your thoughts on tbis old hub, as I have one I may build!❤

Maybe it's because I'm a Sachs' fanboi, but your praises of the Shimano surprise me. Nothing to say about the quality (of the 80s Shimano eh!), but the Sachs' simplicity is still a winner for my taste. Winner for sure over the Positron, just because of that bloody solid cable:-)) Thank you so much for the very interesting video AND for the service you offer to the Community of crazy people we are part of:-)

Great video! Many thanks! I am resembling a H3111 and forgot witch side the little cup on the small spring should be, now I know 😊🙏

i bought a folding bike and it has the torpedo-duomatik-r2110 with blown out inner bearings,also got like 2 torpedo hook wrenches but im unable to get the hub open

hab heute beim schrottplatz so ein ähnliches tretlager ausgebaut um es es in mein klapprad einzubauen bei dem die kurbelkeil aufnahme rund war

Hi =) Thanks for a great video. Did the design change a lot through the years? Mine is a 1938 K.

Thanks for the great video. What an amazing hub.

😮

Is Landing diameter of star 34.9 mm?

really enjoy your content

Moin, Torpedo- Nerd B-) Machste gut. ;-)

Hi, My name is Bob and I am 81 years. When I was 8 years old I changed the sprocket on my coaster brake and I have been building and riding vintage bikes ever since. About 15 years ago I found a rusty Mifa with a like like new Renak and beautiful chrome. I restored it and it is a wonderful riding bike. Many friends think it is my most interesting bike. Yet. I couldn't find information about it. I knew the bike was from East Germany and that's all. I love the crank and I had to modify a gear puller to repack the bearings. So, it's no wonder I love your videos. I also collect coaster brakes. I often find them missing parts and I restore them. I have a super Granat and I didn't know where it was from. I Know my Favorit and Velosteel were from Czechoslovakia but that's all. I loved your history of torpedo and clones. I have never seen a vintage Torpedo coaster brake here in Arizona only clones. In my youth I only saw English Perries and Resilions. Later a lot of Schwinn approved clones made in Germany. There were other clones unbranded or like the Excel Mark IV from who knows where. I also have a like new Durex bicycle coaster brake that I know nothing about. I love the German engineering. I love the way the three speed torpedo shifts. So, I didn't know about the two speed torpedo until I saw your video. I ordered one and it will be my next bicycle build. Thank you Cheers, from a fellow bicycle lover, Bob. I

Very interesting information - thanks for your details.

Hello sir. May I ask what causes slack in coaster brakes? If I engage brake then go back to pedal forward there is a slip or a free spot before it engages?

Really enjoy these videos of yours! Especially Featuring these unique hubs that I've never seen or heard about.

wheelbuilding and drvetest please! brake effect similar to the torpedo can be better, may be.🤔

Great video. I have a Bendix coaster hub I bought from Canada, it's a one-speed, and not disc type. It has good modulation, similar to shimano D-type. Only thing is that is makes a clunk sound after releasing from from heavy braking, as if the spring has a hard time releasing the brake shoes. Have you experienced this before in other hubs? Perhaps I reassembled incorrectly.

Some people advise to you car brake grease for brake shoes instead of vaseline. Do you agree with that?

Sehr schön! Aber: Was empfielht der Fachmann zum abziehen der linken Glockenkurbel? Ich habe mit Freude beobachtet, wie es darunter zugeht und ich meine, verstanden zu haben - aber noch hängt bei mir so ein 1951er Kurbelarm ziemlich fest am leise wackelnden Rest und ich habe erstmal nicht so viel in petto mit meinem 08/15-Werkzeugkasten? Heiß machen und von hinten mit dem Hammer klopfen? So roh...

Hi, ich hab mir ein altes Peugeot Klapprad aus den 70ern gekauft, mit einer 2-Gang Duomatic (mit diesem Öleinfülldings außen;-) Ich bin noch nicht dazu gekommen, auf die ModellNr. zu schauen! Eine Frage: Wenn man das Bremsmantelfett aufträgt und das Öl benutzt, vermischt es sich doch während der Fahrt miteinander? Diese ÖleinfüllÖffnung von außen auf der Nabe: Man sollte da Öl nachfüllen? Jetzt wirst du vielleicht sagen, dass das Quatsch ist, aber dennoch die Frage: Wenn ich in meine Schaltung Öl einfülle - von außen - und sie ein bisschen fahre, um dann das Öl abzulassen: Reinigt sie sich nicht dadurch auch? Ich weiß: Nicht so gründlich, als wenn ich sie wirklich auseinandernehme und reinige. Klar ist das besser! Grundsätzlich: Kann ich Getriebeöl nehmen? Bremsmantel: Seh ich das richtig, dass der aus Kunststoff sein kann? Dann soll man Vaseline nehmen? Ich habe noch Bremsmantelfett für meine Shimano-Nexus-7-Gang. Das kann ich nicht nehmen, weil? Weil es den Kunststoff angreifen kann? Ich hatte einen schweren Unfall und fang erst mal mit Klapprad an, weil kleiner. Im Moment kann ich noch nicht soviel herumbasteln. Deshalb die Frage. Grüße nach England;-)

Schöner Einblick mit nützlichen Erklärungen. Seit kurzem hab ich ein umgelacktes altes 20 Zoll mit Duomatic. Noch mit Flügelmutter anstatt Knebelschraube; Hersteller leider nicht bekannt.Die Übersetzung erzeugt mehr Fahrspass als die 3 Gänge eines Aldi Curtis 20 er Klappis.

Danke für die Anleitung - super Video 👍🏻👍🏻. Eine Frage hätte ich jedoch: Welche Kugeln (Durchmesser) kommen auf der Pedalseite hinter der Filzdichtung zum Einsatz? Diese haben ja keinen Kugelring und liegen lose im Lager. Finde leider keinerlei Info darüber. Die Kugelringe Star K58 und K65 sind eindeutig.

Sram Automatix is cancelled from production or not ??

Č Z - Česka Zbrojevka - Czech product

Hello, I have an old sram automatix hub and I try to follow your video instruction, but somehow I reoiled and put it back to my bike, somehow my foot break dont work, only spins 360 degrees. Why can you give me any tips?

why do people put them stupid gear shifters on racing frame even on 90s frames had bar shifters and ergo shifters

i miss derailier

i use shimano 7spd but i prefer sturmey/archer because of the chain to hub im angry with sram they stopped chain on 7 spd

is the duomatic hub different from the automatic model hub? are they both different hubs? if so what is the difference in both hubs,automatic and duomatic?

hi frank,is the 102 duomatic hub the automatic model ?do you change gear by half peddal stroke kick back?or dose the automatic gear change without kickback stroke?

i could do with a specialist near me mine needs new bearings

Fascinating... it will rebuild nicely now!❤ I need a small hook spanner like you have. For the locknut on my Styria CB.

Ah just perfect a Coasterbrake upload after a long day in the shop! Good work Jens!

I enjoyed this immensely. You were not content to know a little. All the way in! Salute! Are they the greatest invention ever? Top of the list I bet! 😊

but very difficult to remove when rusted on

People seem to like the Bendix 70. I have found it to be cheaply machined. Lathe turning marks on the races. Not remotely as good as Torpedos or any clones!

will it be ok to use grease on the brass brake because had no vasaline

Awesome! I hope you cover the Austrian Torpedo clone Styria. I have one, machined like a rolex.

hi frank mate,i have a duomatic two speed 102 i have noticed the is a sqeaking sound from the hub,can you tell me what this is?greetings from liverpool england

Dear Jens, I hope you are well. I want to thank you very much for the videos you have uploaded to RUclips, they are some of the best about the Sachs brand. They are helping me a lot to restore a bicycle that I was able to buy in Argentina (a Dahon 3). And about this I would like to ask you if you could please help me resolve some doubts. The first thing I can't identify is the year of manufacture of the bicycle, nor the year of the torpedo model since it doesn't say it anywhere. It only has a number 28 on the rear hub, but with that I couldn't tell what year it is. The second question is that I don't know what model of the sachs torpedo system the bike comes with since it doesn't say it anywhere, it is very similar to the Torpedo Model 415 without brake, but when I opened it, it is not the same as the 415. So I don't know what model it is, to try to find some video with that exact model to be able to disassemble it, clean it, reassemble it, grease it and oil it correctly. ACTUALLY I took it apart, cleaned it and all that, but I don't like how it turned out and I guess it was because I wasn't able to see a video of the EXACT model that I have and I just did what I could. I am attaching some photos in the email so that you can please help me if possible to identify the year of manufacture of the bicycle, the year of manufacture of the torpedo and the exact model of the torpedo. I will be very grateful if you can give me some guidance. Have a nice week.

is it easy to "shift"? And has it got a good "range", meaning that it has a real benefit over running that gearing without the Gearbox? I am considering to integrate a Duomatic into my old folding bicycle because it is really hard to go up inclines in the current state with only one gear. Do you think this would help?

Why don't you clean all parts in solvent before re-lubricating them? Is that not necessary? Thanks for the video.

Alter Schwede - was für ein Gepfrimel, wenn der Drahtesel so in die Jahre gekommen ist... ;)

Super interesting thank you so much. I learn a lot from your videos every day!

Geht das ganze eventuell auch in Deutsch? Danke!

Damn I haven't even noticed you had a YT channel! I'm a huge fan of the Torpedo family (for good reason!) and this video was super interesting thank you! Gotta say that golden and blue color was really nice, not thinking of the mess happening inside off course:-)

Can you help me: should the Sturmey Archer SC hub have a circlip on the driver or the driver roller retainer? The manual says it does, but I dont think I spotted it on my used hub and the driver definitely doesnt even have a place for one.

thats such a cool design, i will never see it myself in real life but amazing. replacing the brake pads will be a nightmare if you do not know how to disassemble it😅.

Asbestos could be a problem, but not with this drumbrake full with grease. If you are afraid about, dont touch and open a ADAX.

Looking at these parts ... no wonder all lasted a generation and longer
