OC Dropper Post MC21

The MC21 Dropper post is cable actuated, so it never needs bleeding and provides lightweight performance in all circumstances and conditions. The drive cable runs inside the seat post's vertical tube for a clean fit. With its range of 50mm to 230mm of travel and a low overall height, you can easily find your perfect fit. The sealed hydraulic cartridge, cable-actuated remote control, nylon bushings, and waterproof seals provide long-lasting, reliable operation. With completely replaceable parts, distributed by Orbea, maintenance is simple.
