I've gotten great guidance for my first bike build (75 Motobecane Nomade) and things are going well. But I've left the hardest part for last - HA! I have a Huret (not sure of series) RD that doesn't seem to fit on the frame (see pic below).

The dropout has a raised surface that doesn't let the fitting part of RD (resembles the letter "C") lay flat against the frame. It also has this set screw (two flat sides and round on each end) that I'm not sure of its position - I assume this locks the position once set.

I shouldn't have to file away the profile of the RD to make fit should I? I've tried all kinds of placement and nothing seems to work - any advice for this non-French savvy newbie mechanic?

Many thanks...

Any chance you could post a photo of the dropout on the Nomade? Is the raised area you mention part of an eyelet?

The removable part of the hanger that the set screw threads into should be installed along the inside of the dropout with the curved part facing the rear of the dropout. The hanger is installed on the outside of the dropout. The set screw will snug it up.

Yeah we'll need pic of the dropout and perhaps the derailleur hanger next too it... when you say raised bit it makes me thing you have a dropout that is either forged (which would most likely have an integrated hanger) or one of those old simplex stamped drop-outs that have another plate brazed to them for extra strength (at least that is how I think they are constructed. I could see a problem of the bolt which hold the hanged in the dropout being a little to short if the DO is too thick but then you could just use a longer bolt.

Here is a "before" photo of my Nomade Huret Allvit RD. That derailleur you have I believe is a much better one called the ECOS which is on my 1987 Peugeot P4 Corbier. I wonder if your Nomade was upgraded? The claw for the Huret Allvit has the name Huret on it but I cannot see that on yours.

I know it's low resolution (will post better one when I get home if needed) but hopefully you can see problem area. There just isn't enough clearance unless I were to use washers to build up clearance. OK, take a look.

Thanks for the pics...yes, you should be able to slightly make out "Huret" stamped onto the connector part (hanger?).

Hey TRHOUSE,

Ecos eh? I went to this page to try and find a match for reference but didn't see one exactly like it. After seeing your post, I revisited but couldn't find "ecos" on the page. It's a mystery, although the series name is the lesser problem at hand (still curious though).

The hanger doesn't have to be buried all the way to the end of the dropout. Can you cheat it forward some to clear that eyelet?

Otherwise, yes you can safely grind off part of that hanger to gain some clearance. Between the set bolt and the pressure of the quick release, the hanger is not going to go anywhere. I think simply moving the hanger forward some is really all that needs to be done though.

A nice Huret gallery here.

I took the Huret Allvit off my Nomade to check and found the dropout is perfectly flat as I remembered. I cannot explain why yours would have a bump there. The photo is too blurry to make out what it is. Does it look factory?

The Huret ECO S is a very nice derailleur. I wish my Nomade had it. My Peugeot has it without the hanger or claw.

Nick Burns link does show it but for some reason the photo of the ECO is minus the gray plastic covers. I think the S just means Sachs after it became Sachs Huret. Here is someone in your neck of the woods selling one on eBay.

The pic is a bit blurry but it looks similar the stamped dropout on my Peugeot UO-8. In that case, the raised portion is for the eyelet for a fender or rear rack. The original claw is shaped such that it doesn't interfere although on the Pug it really doesn't look like it would be an issue anyway.

[QUOTE=ken_matthews;6462187]Are you trying to fit the RD hanger through the fender eyelet? it should be fitted through the dropout were the axle goes.
The hanger goes on the outside of the dropout, the small part held to the hanger by the setscrew goes on the inside of the dropout with the raised part sitting snuggly in the dropout groove, put the set screw back loosely sandwiching the dropout between the two hanger parts.
Slide the hanger right to the back of the dropout and line the big cutout in the hanger with the axle slot in the dropout (sp that the axle can slide in.) when everything is lines up correctl; tighten the setscrew.

Thanks all, I was able to get it on with your help. Now I just need to check the spring as it seems loose (and there are 2 notches the end could potentially go on). For now though, it's on the rear dropout so that's progress! Will post a pic shortly...KEN

As promised...after reviewing TRHOUSE's photos above, I realize the cage is in the wrong position. I'll try swinging it around to slightly behind the cogset. Should the chain when threaded through, provide a tendency to push the cage into an upwards/outwards position?

Take a look at this photo:

That is how your derailleur cage should be oriented.

You will need to wrap the derailleur cage around one turn and put the spring in the slot with the number that most closely matches the number of teeth on your biggest freewheel cog.
