Bottom brackets

Středová složení pro biketrialové a cyklotrialové kolo musí splňovat několik základních požadavků. Musí být extrémně pevná, obsahovat velice kvalitní ložiska a také musí být lehká! Nejpoužívanějším typem středových os pro biketrial jsou ISIS osy, nejčastěji z ocele, ale také z titanu. Druhou variantou je nastupující generace klik spojených s provlékací osou typu AS30 / PF30. My Vám nabídneme všechny varianty a tak je pouze na Vás, kterou si vyberete!
