This cycle part is a 2-piece derailleur screw set designed as a gear adjuster for M5 universal threaded applications, making it suitable for cable-actuated shifting systems and road brake lever use. Each gear adjustment screw is built to fine-tune cable tension and shifting position, helping the cycle tension screw setup stay responsive during routine drivetrain and brake adjustments. The derailleur screw combines a nylon outer shell, a CNC aluminum alloy adjustment screw, and a stainless steel coil, creating a compact assembly with a visible coil through the side opening. Each piece features a rectangular body with a cylindrical top section, an anodized aluminum finish, and stated dimensions of 18 mm × 9 mm for the shell and 26 mm × 7 mm for the screw. This cycle part is intended to support precise adjustment in shifting and brake cable applications, offering a compact replacement component for maintenance and setup work.
