Serpent 977 aluminium CVD driveshafts
For the 977 and 966, Serpent now offers front and rear CVD driveshafts in hard anodized 7075-T6 aluminium. Laser engraved with the length and Serpent logo these are around 50% lighter than the same durable units in spring-steel meaning an important reduction of rotational masses to improve acceleration and braking. The pair of front shafts are 7.15 grams, while the rear are 7.8 grams.
