J aime bien les tubes  petites collecte de doc et photos sur les tubes aero dont j ai decouvert qu il n y avait pas seulement eu Camus aero 7 et SV Arcor 980 mais aussi du tange qui s appellair notamment "Tange Aero Dynamics" souvent couple lui aussi au Shimano 600AX   Velos Un un Mercier Formule 1 avec du simplex et un pedalier Tevano mais qui semble avoir une tds profilee a la difference de bcp d autres modeles - je ne sais pas si c est du camus ou autre   Un Fantino  Un Gitane avec Shimano 600AX  Un liberia en Camus aero 7  un Koga Miyata en Tange Aero Dynamics Apparemment, ces cadres étaient produit par Miyata Japan à la demande de Shimano pour ses groupes AX. Ils étaient ensuite badgés à la demande des marques (Kristall, Jan Jenssen, Norta, Mustang, ...) en fonction des gammes et des finitions. Un des tube est le "Tange Aero Dynamics."  Un cadre Norta  |

bonne idée de continuer ici plutôt que là: forum.tontonvelo.com/viewtopic.php?f=30&t=17799sujet où bduc demandait si une tube de selle SV 980 arcor profil non ovalisée était possible. Oui Romuald, c'est aussi le souvenir que j'ai de l'apparition du F1: un encart pleine page en 2 temps (à une ou 2 pages d'interval) dans Le Cycle. |

Sur les Formule 1 il me semble que toutes les tubes de selles sont ovalisés, que ce soit 26/28, SV 971 ou SV 980. C'est d'ailleurs pour cette raison qu'il faut impérativement que la tige de selle soit présente sinon grosse galère en perspective (à expandeur en plus).

Il existe aussi une série profilée chez Reynolds, le 531 SL Speedstream, mais je n'arrive à trouver la documentazionne. www.retrobike.co.uk/forum/viewtopic.php?t=202907Oui m'enfin quand même  Ce qui tendrait à laisser à penser qu'il y a Speedstream et Speedstream SL.  |

Allez , un petit tour chez les Anglais Le Lotus Super Pro  " Super Pro Aero
Tange Aero Tubing and Frame Label
If Lotus, a young company in the early 1980's, wanted to make an impression on the cycling community with their new line of bicycles they certainly did with the Lotus Super Pro Aero. Equipped with the then new aerodynamic Shimano Dura Ace AX group and built with Tange Aerodynamic tubing the Super Pro Aero was the flagship of the Lotus fleet.
It's easy to view this bicycle today with jaded eyes, but back in 1981 there were not many bicycles like the Super Pro. The hidden brake cables, aerodynamic oval tubing, smooth aero components, and triangular water bottle were all very new concepts at the time and actually quite shocking. We remember seeing the "new" Super Pro Aero on the showroom floor for the first time back in 1981 and we were awe struck.
The Lotus Super Pro was built using Tange Aero Dynamics CR-MO Butted Tubing.
In June of 1981 Lotus sponsored Jim Black to ride the Lotus Super Pro from Santa Monica, California to New York, New York in an attempt to break the transcontinental world record.
The Super Pro was so impressive that it was featured in the July 1982 issue of Popular Mechanics Magazine. (See the scan here). The fillet brazing and hand-made details on this bicycle made it time consuming to build. It was also nicely equipped with top-of-the-line parts. The 1982 price for the Super Pro was listed at 1,200 dollars, in today's money that's about 2,800 bucks.
By 1983, Lotus also offered the Aero Sport, a lugged aero frame with Shimano 600 AX componentry and clincher rims instead of tubular rims.
Below is a very well preserved example of the Lotus Super Pro Aero. The water bottle is an original component to the bicycle as is the Kashimax Aero leather covered saddle. Kashimax also made a hard plastic Aero saddle without the covering, for BMX use. The first generation Dura Ace AX and 600 AX brake hoods were a light blue-green color.
Lotus offered a top-of-the-line conventional frame bicycle at the same time as the Super Pro, that bicycle was the Lotus Supreme. "  Specs 1981 Lotus Super Pro Aero

Notes Shimano Aerodynamic Water BottleArticle Dans Popular Mechanics ou incidemment on decouvre a cote dans la deuxieme page un Puch AD - Austro Daimler avec un seattube a la "Mecacycle Turbo"    Avec des Raccords et plus soudobrasé le Aero Sport "Aero Sport Tange Aero Tubing and DecalIntroduced as a compliment to the popular Lotus Super Pro, the Lotus Aero Sport utilizes Tange Aero Dynamics CR-MO D.P.G. tubing, similar to the Super Pro, but features a fully lugged frame instead of the fillet brazing found on the Super Pro.
D.P.G. stands for Double Plain Guage, meaning the sides of the tubing have thicker walls than the curved top and bottom sections.
We believe the Tange Aero Tubing was available before the special lugs had been designed to accomodate the oval shape, this is why many early frame manufacturers using the Aero tubing opted for the more expensive and time consuming fillet brazing process. Using lugs simplified the brazing process and allowed the frame to be manufactured less expensively.
The CR-MO D.P.G. tubing was probably less expensive to produce than the CR-MO Butted tubing used on the Super Pro. Anecdotal evidence suggests that the Aero Sport cost approximately $800.00 while the Super Pro was $1200.00, offering a great value for a quality aero bicycle.
The Aero Sport used the Shimano 600 AX group of components, very high quality yet less expensive than the Shimano Dura Ace AX group found on the Super Pro. The Super Pro also came equipped with tubular rims and tires, the Aero Sport rode on clincher tires and Araya 700 x 25c Aero clincher rims.
The Aero Sport was only available in two colors, the first models were all "Silver Champagne" and later Lotus added "Oxide Green" as shown on the bicycle below. Both models were originally equipped with "champagne color" Kashimax Aero saddles." Specs 1982-1983 Lotus Aero Sport

Les tubes ovales allégés Mercier étaient badgés M35-20 : Hum, vues ailleurs ces photos... C'est normal que l'appellation soit un peu différente, mais elle doit s'appliquer à la même nature d'acier. M28-26 --> M pour Mercier, 28 pour 28 mm des tubes de selle et oblique et 26 pour 26 mm du tube supérieur. M-35-20 --> blabla et 35-20 pour tubes de selle et oblique ovalisé en 35,5x 18,5 mm (en arrondissant, prenait trop de place avec les virgules). La série SV 980 Arcor joue un peu sur les mots car seul le tube supérieur est effectivement en SV 980, pas le reste. |

La série SV 980 Arcor joue un peu sur les mots car seul le tube supérieur est effectivement en SV 980, pas le reste. tu veux dire par là que seul le tube horizontal est en 5/10 renforcé 8/10 (comme le SV980 "standard", habituel. "inchangé" comme dit la doc.) alors que les t. diag. & de selle profil Arcor sont en 7/10 renf.10/10? |
