La Nouvelle Forme d'Adamo

The New Shape of Adamo

Les modèles de selles à nez fendu ont fait sensation ces dernières années. Au départ, les selles étaient un produit marginal, adopté seulement par un petit coin du marché du triathlon. Plus récemment, ces selles sont apparues sur les équipements d'élites vainqueurs de courses, notamment le vélo TT du champion du Tour de France Lance Armstrong. Forts de leur expérience et de leurs années d'utilisation, les ingénieurs d'ISM ont affiné la forme et la fonctionnalité de leurs selles Adamo et ont introduit un nouveau design qui apparaît dans les modèles Podium et Breakaway. Pour entrer dans le vif du sujet de ces nouvelles selles, revenons d'abord sur leur prédécesseur.

L'Original Adamo

 

L'original au nez émoussé n'offrait pas beaucoup de place pour bouger

 

La selle Adamo à nez fendu a été conçue pour résoudre un problème rencontré par de nombreux athlètes lorsqu'ils sont dans une position de triathlon basse et agressive avec rotation du bassin vers l'avant : les selles ordinaires font mal. Une selle conventionnelle a un nez fin qui n'est normalement pas très utilisé, car les cyclistes sur route sont assis sur la moitié arrière de leur selle. Les triathlètes, en revanche, sont assis beaucoup plus en avant et, avec un bassin tourné vers le sol, une fine selle en forme d'aiguille exerce trop de pression sur la région du bas. Un nez fendu, en revanche, entre en contact avec les os de la tubérosité ischiatique (les « ischions »), gardant les tissus sensibles heureux et confortables.

Le problème avec la conception originale est qu’elle était un peu trop spécifique. Un cavalier devait rester dans une position sur la selle, sans avancer ni reculer pendant le trajet. Reculer était inconfortable en raison de l'arrière très large, et avancer ne fonctionnait pas car la selle se coupait brusquement à l'avant.

La Nouvelle Race

Les nouveaux modèles Podium et Breakaway d'ISM répondent aux plaintes ci-dessus. Tout d’abord, on constate que les designs sont identiques. La seule différence entre le Podium et le Breakaway est, soi-disant, la quantité de rembourrage dont ils disposent. Le Breakaway est censé en avoir un peu plus, mais nous n'avons pas vraiment pu déceler de différence à l'essai. Les selles sont, à toutes fins pratiques, identiques. Si les modèles sont ostensiblement destinés au marché routier, ils constituent en réalité une avancée pour les triathlètes. Vous voulez vous asseoir plus en retrait ? Pas de problème. Les partisans du design original diraient que si vous n'étiez pas à l'aise avec l'arrière large de l'Adamo d'origine, alors vous n'étiez pas assis correctement sur la selle. Qu'il n'a pas été conçu pour être assis de cette façon. Eh bien, ces critiques ont raison, mais qu’y a-t-il de mal à vouloir changer de direction ?  Se déplacer le long d'une selle est une chose normale, et il peut être frustrant d'être forcé sur une seule partie de selle de 2 cm de long sur 112 miles.

Le Podium et le Breakaway résolvent assez bien ce problème. L'arrière ne s'évase pas aussi rapidement que l'ancien Adamo, ce qui permet un mouvement plus vers l'arrière. Vous ne pouvez toujours pas reculer aussi loin que vous le feriez sur une selle traditionnelle, et vous ne le voudrez pas non plus. Le nouveau design vous laisse juste assez d'espace pour vous déplacer afin de s'adapter à différents groupes musculaires lors de ces longs trajets.

Mais la véritable histoire de ces selles réside dans le nez. Continuer à lire.
