Transmission VTT : un rouage important de votre vélo
La transmission de votre VTT est un composant essentiel qui associé aux freins constituent le groupe de votre vélo. Sur l’équipement du VTT, deux marques se partagent le marché : Shimano et SRAM. La transmission VTT comprend donc les commandes aux guidons, les dérailleurs avant et arrière, la chaine, le pédalier, la cassette et les câbles et gaines qui permettent de relier les commandes aux 2 dérailleurs.
Aujourd’hui la transmission mono-plateau se développe et ainsi le dérailleur avant disparait. SRAM et Shimano proposent différentes versions de leur groupe phare (XT et XTR chez Shimano et Eagle et XX1 chez Sram) en mono-plâteau.
La transmission VTT au cœur de votre pratique
Suivant votre discipline, vous n’aurez pas les mêmes besoins en matière de transmission. Le choix d’une transmission impacte notamment l’étagement des vitesses qui ne sera pas le même entre un 3x9 vitesses et une transmission 1x11v. Ainsi si vous faites de la descente, votre choix se tournera plus vers une transmission solide et n mono-plateau qu’une 3x9 vitesses.
