关于下面那个EMT轮毂的介绍,网站里是这么写的 EMT (Energy Management Technology) is Matter's newest hub
design. Taking the Hollow-Core and incorporating a concept of substantial rebound for outdoor, EMT completely maximizes your efficiency.
This new design turns the entire core of the wheel into a spring,
allowing it to give back virtually all the energy put into every push.
EMT allows for flex and thus gives you incredible grip as well.
