it's been raining for the past three or four days, so haven't really done much progress on the Super Sport. The derailleurs are on and I swapped the Bluemels to chromed fenders (also from a DBS of the same age) that have matching black striping. Still need to do the brake cables, true/center the rear wheel and decide on the number of speeds and gearing for the rear.


My example of the Allvit came with the hanger attached so I went through some Huret manuals to see if the use of the part "1804" was needed when using the derailleur with the forget Huret dropouts. I also wondered if the RD was ment to be set with slack in the fitment to the hanger because if tightened all the way it would not swing back to allow the rear wheel to be removed easily.

This manual, possibly from 1961, did not give any answers.


This manual, possibly from 1972, did have the answers.

"-For use with HURET monobloc forged rear ends the fixing bracket supplied with the gear will not be requi red. This should be removed and the mechanism mounted directly to the frame with the allen-headed bolt and nut A (Fig. 1), placing the friction washer between the mechanism and the frame fork end. Ensure the articulation remains smooth and free from side play when the lock nut is tightened."


"For Racing and Touring"
The Allvit was marketed as 3/4/5 speed in 1961, but by 1966 also as a 6 speed. I might go with a 6 speed freewheel.

This catalogue page from "Huret Accessoires de Haut Qualité pour Cycles et Motocycles - 1968" gives instructions for shifter mount and cable stop placements and for correct cable housing lengths.

Never been to that site before. Did have a quick read on couple of posts on the blog side. Always interesting to read about "Long-Cage vs. Short-Cage Derailleurs", vintage derailleurs, capacity, gearing...

Not really "well beyond", always something to learn. It was a good read and I found the readers comments about the compability problems with Shimano UF and Huret dropouts on that post intriguing.
I'll post some pictures of those dropouts with different derailleurs later.

Thanks.

Jonas' birth annum of 'lxvii places him near the transition betwixt all metal pulleys and those with plastic "tyres"

for meself would lean toward the all metal

Freres Huret continued to employ images of mechs with the all metal pulleys in catalogue and instruction illustrations for a couple year after the change

[perchance too thrifty to commission Danny Rebour for new drawings!]

just don't ask me about when the black versus the red "tyres" were used!

this Sir Wally catalogue page of nineteen seventy illustrates the temporal overlap regarding the introduction of the pulley "tyres"

the Gran Prix model is shown fitted with a Luxe Touring rear mech which wears the all metal pulleys whilst the Record model sports an Allvit model stern mech fitted with red "tyres" pulleys -

I have the one with all metal. Posted a picture of it few pages back.

Hideki Sasaki in his book "Derailleurs of the World – HURET" dates the one with the red star logo "Allvit" sticker on the front and with the red pulleys from '69 to '72.

Would love to have the Luxe Touring RD.

This Huret Allvit is the 2nd version, iteration B from 1962? According the Hideki Sasaki's book on Huret derailleurs.

This final version Gran Sport was original to the bike. These old bronze Campagnolos somewhat work with the Huret dropout as part of the upper knuckle hits the hanger stop before the actual stop on the derailleur.
Simplex or other than these two pictured derailleurs meant for Campagnolo style hanger will not work with these Huret dropouts.


Here with Campagnolo Record.

Tested eight different derailleurs with the semi-vertical Shimano UF dropouts and all seem to work fine. Well not tested, but atleast they all mount correctly.

Shimano 600 EX Arabesque, the period "correct" one for these dropouts.
I believe Shimano made the second stop or "back stop" to essentially lock in their style of hanger stop (the wide b-stop) in the dropout, so that the derailleur would not swing back and hit the dropout or seat stays. Did not really find anything on this, all is just speculation by me.
If the hanger bolt/spring/b-knuckle assembly is sticky, gummed up, the derailleur is somewhat hard to mount to this hanger as the gap for the stop is narrow and the b-stop will want to spin with the bolt when mounting the RD.

Suntour Cyclone

Campagnolo Nuovo Record


Simplex LJ 4000. The stop on on Campagnolo style hangers can "dent" or "eat away" the Delrin on the b-knuckle.


Sachs-Huret Rival Aris.


Campagnolo Racing Triple (8 speed).


Shimano Deore LX (M550)


Sachs-Huret Rival modified to "work" like Simplex derailleurs that are Campagnolo style dropout compatible.
I got this derailleur with the derailleur-side tab of the b-stop bend and wondered if it would work like this (comparing to the other Sachs-Huret the correct position can be seen, and in this picture the mark where the tab has went over the knuckle can be seen).
Turning the tab/b-stop about 150 degrees back will unwind the b-knucle tension spring resulting loss in the spring tension.
I don't have any frames with the Simplex hanger, but testing this on the Shimano hanger I would say this will work with Simplex hangers that have the 9mm bolt hole, only modification needed to the hanger would be to drill the hole to 10mm and tap it.
