Clarks 30m Gear Outer Casing – SP4 Workshop Pack – 30m
he Clarks 30m Gear Outer Casing SP4 Workshop Pack is designed for professional workshops and home mechanics who demand durability, smooth shifting and long-term reliability.
Manufactured using advanced double-jacketed Kevlar fibres, this high-performance gear casing features a braided PVDF polymer underlay combined with spiral fibre wrap reinforcement, delivering exceptional strength and resistance to impact and expansion. The result is consistent cable performance and precise shifting across all riding conditions.
Supplied in a highly durable dispenser box, the 30-metre casing is neatly wrapped around a central wheel, allowing the hose to be pulled smoothly from the box and cut cleanly to size. This makes it ideal for busy workshops, mobile mechanics, and regular servicing.
Fully compatible with all major drivetrain brands, this Clarks gear outer casing is suitable for a wide range of bikes including MTB, road, hybrid, BMX and e-bikes.
