Hi folks - looking for an old Huret, Suntour, or Shimano RD that will work with a Huret dropout on a '74 Motobecane. Doesn't have to be really pretty, Modern Campy standard stuff doesn't fit. I understand some Shimano Titlists work and some Suntour VGTs. Cranes as well, but not lookingvto invest a ton in this. I have MANY derailleurs from the 70s through 90s to trade / trade +/- $. Or just outright buy.
I'd also be interested in a hanger that would fit the dropout and let me use any derailleur. I must have tossed them all or left them in a parts box I gave away long ago.
Or... an actual adaptor that would let me use the Campy standard on this dropout...
Thanks to anyone who can help out here.

I'm in need of a 1" threaded fork for a small bike. Head tube measures 10.5 cm, so likely I need something with a 12-13 cm steerer. English threaded, preferably. Not fussy about eyelets or rake; as long as it's reasonably straight or easily straightened (I have tools). TIA!

Wheel size and brake configuration.

Likely 700c and caliper brake.

I might have a fork for this, it will be Belgian/Ital if I find it...can you guess that make?
BTW it will will be a few days until I can look, but pretty sure it's still there, waiting for a new home...

Thanks, but looks like @scarlson will help me out with some steerer trimming and threading with a fork I have in hand.

no problem...but can @scarlson add threads to a steerer? If so I need to put him in my Rolodex!

scarlson 

Yes indeed I can!

That's a great skill (and IMO harder to find than ever!)
I'm making a note of this in my BF memory book...

It isn't so hard! All you need is a die and a die holder. And you don't need a bike-specific die either. You can buy one on ebay that will do the job: 1" x 24tpi. The die and die handle together cost maybe $35. They are cheap but they'll do the job. The die is the simple, non-slotted type, so you can't adjust fit. For me, this was fine. It is also possible to cut a slot in the die using an angle grinder, to have it expand a little bit so you can get a little tighter fit if you so desire. I have done this with dies in the past.

I also recommend leaving some original threads on the fork so you can easily start the die. Thread however far you want, then cut the steerer off. Getting any large-sized die started, even the bicycle-specific ones with pilot guides, is hard.

But anyways, the point of what I'm saying is that you, too, could have this ability, probably for about the price of shipping the fork out to have it done!

^ right about getting a die started, even on existing threads, being tricky.
I once had a shop ruin a steerer/fork by cross-threading and then cutting botched mis-aligned threads, this done by a novice "mechanic" with a bike-specific die.
That shop is long gone.
Been turned down by nearly every shop since then (most have heard the horror stories and don't want to risk it) one even said "we don't want to ruin our die"
Saving it for what, a special occasion?
Based on this I only had threads cut since with a lathe by an experienced lathe operator...I was hoping you were one of them: the few, the brave...

scarlson 

Oh sure, I can do it on a lathe. I have done it on a lathe. I just don't *like* to do it on a lathe. It's hard because the fork legs are super long and they twirl around and I think that's dangerous. Also can be hard to find the true center, if the brazing under the crown is rough. Also don't like it because even if you are both daring and skilled, backing the tool off before releasing the half nuts is iffy. If you don't back the tool off, and are threading down the fork, you will get a groove in the metal wherever you stop it. I don't like the stress riser it creates. And if you are machining up the fork, you can't start the tool off the material. You have to plunge the tool in by feel, as you are making your passes. There are way too many ways for it to go badly. I got the die for that reason. I figure if I have the skill to use the lathe, I have the skill to use the die correctly. Sometimes you can even put the thing in the lathe and then, with the power off/gears in neutral, start the die, using the lathe as an alignment tool. Easy enough. A piloted die holder is ideal of course, and could be made by machining - more easily than making threads on a steerer in the lathe! And then you'd have it forever. Basically get an aluminum round stock bigger in diameter than the die and maybe 4" long. Make a bore in one end the size of the die, and a bore in the other end that is 1" in diameter for the steerer. Then it would be impossible to misalign. Drill and tap holes in the sides for the set screws and long handle rods. Would be stronger than the lousy pot metal die holder I bought. I may do this if I ever have time.

Are Universal hoods available anywhere but EBay?

Appreciate the info!

Once again coming to the forums with a request for my good friend (and state judge) . He has given up on riding his road bike and is asking me to find it a new home. 53cm trek 1000 with a bunch of accessories, shoes, spare cleats. seatpack, etc. Also comes with a two bike Thule over car bike rack. He wants me to be sure it is not a flip but that it will go to loving new home. Any one who can help with my how to give a nice bike away problem? Smiles, MH

Looking for an old school derailleur hanger with bolt/nut hardware, the kind found on inexpensive 70s and 80s bikes. Using to mount a derailleur on a Huret dropout and I don't have the Huret to Campy adaptor. I do have a hanger but no mounting bolt and the nut that fits in the dropout slot (see pic) . I just have the plate. Any help appreciated!!

Schweinhund

So this is what you need? Just the flanged hanger nut or both sides? (got the missing screw too)

ehcoplex 

Anyone have a tall Technomic, 26mm clamp with a relatively short reach (60 or 70 ideal, but 50 or even 80 would be workable) laying around? Dinged, scratched, in-need-of-polish, all fine! Thx

Schweinhund

He said
Is he not saying he wants the nut and bolt? Looks that way to me. The nut is in the picture and I said I have the bolt.

msl109

The picture is just to illustrate - it's not mine. I need the nut and the bolt. The nut is most important - I'm sure I can find a bolt.

Schweinhund

pm your mailing address, you want the NDS spacer too?

I love the English translations of some of these things, e.g., "cocotte tension dumpling."

Let me know if this would work…
