“SUPER-LEGER LUXE”
HAUT
BAS
Toujours désireuse d’améliorer la gamme déjà étendue de ses productions, la S.A. BOCAMA vient de créer une série de raccords appelée SUPER-LEGER LUXE de conception toute nouvelle aussi bien par la finesse de sa découpe que par le métal employé pour sa réalisation (12/10 d’épaisseur).
C’est la PLUS LEGERE de nos séries. Elle vient parfaire encore le montage des bicyclettes de très haute gamme et doit être utilisée avec des tubes de cadres de 3 à 6/10 d’épaisseur pour faciliter techniquement le brasage.
Le raccord de selle a 2 variantes – moyennant un supplément de prix, il peut être livré avec une seconde pointe tournée vers le bas. Dans les 2 cas, le raccord de selle est livré uniquement sans oreilles embouties pour serrage rapporté soudé.
La série SUPER-LEGER LUXE ne comporte pas de collerette. Elle peut être livrée avec ajour sous réf. R1 ou sans ajour au choix du client ;

TETE de FOURCHE
“SUPER LUXE”
selon procédé SPECIAL D
Cette tête de fourche est la plus belle réalisation de tête de fourche connue et elle est destinée bien entendu à des bicyclettes de haut de gamme.
Elle diffère des autres par sa ligne particulièrement racée et sa découpe en forme de triangle sur les fourreaux s’harmonisant parfaitement avec nos séries COMPETITION 75 et 78 et nos séries SUPER PROFESSIONNELLE et PROFESSIONNELLE.
Elle est livrée alésée ∅ 25 ou 25,4
pour fourreaux 29 x 16.
Sur demande, nous pouvons la personnaliser avec le nom ou la marque du client moyennant un supplément pour une commande minimum de 250 pièces.
