As rodas e os cubos traseiros SHIMANO estão equipados com 18/16 entalhes para engate rápido.
In contrast to road racing, MTB XC tracks have many sharp turns and steep hills, where quick engagement is essential.
SHIMANO has improved the rear hubs of its high end MTB group sets and wheels and equipped them with 18/16 notches and two sets of pawls to double the engagement and optimize traction.
