後變導輪 - Campagnolo 12s NW Pulley Wheels

Lowest possible friction 最低磨擦阻力

後變速器上的導輪是自行車上轉速最快的零件。在迴轉速最高時，公路車導輪的轉速會比五通軸承高出 4 - 5 倍 ( 依齒輪比和騎士車速而定 )。這表示低磨擦阻力導輪是極為有利的。我們後變導輪裡的 CeramicSpeed 培林，幾乎消除了標準導輪產生的阻力。CeramicSpeed 導輪除了將鏈條導引至理想路徑外，同時還具有平順且精準的變速性能。CeramicSpeed 導輪結合最低的磨擦力和長效的使用壽命，並提供鋁合金和鈦合金兩種版本的導輪，支援所有品牌的單車套件。
