DF 技术 

极致简化的防踏板回击系统

全新 DF 技术是一款极致简化的防踏板回击装置。DF 技术直接在踏板回击发生的源头 – 棘轮机构中发挥作用,有效避免避震器压缩时,链条将不必要的拉力传递至曲柄。如此一来,骑士可在下坡骑乘中不受链条干扰,真实感受来自地形与车体自然回馈。

所有 Ratchet DEG 棘轮系统棘轮系统皆可改装,相比其他解决方案更为轻量。只需更换花鼓棘齿环和两个星状棘轮,即可实现三种不同转动角度:0°、10°和 20°。


DF = 0°

Ratchet DEG 花鼓的咬合角度保持不变,因此不会影响车架的动态踏板回击特性。0° 设定适合重视快速咬合的 Cross Country 骑行。


DF = 10°

棘轮系统在咬合前有 10° 转动角度,可显著降低踏板回击。10° 設定適合 All Mountain 骑行,因为在这类骑行中,踏板回击会变得明显,通常在调整车架设定时也会纳入考量。


DF = 20°

棘轮系统在咬合前有 20° 转动角度,可最大程度抑制踏板回击效应。20° 設定適合 Enduro/Downhill 骑行,通常踏板回击会是车架设定的重要考量之一。
