The Beginnings Of cSixx

cSixx is a South African mountain bike component manufacturer specialising in high-performance MTB, e-bike, road and gravel components. Founded by rider and engineer Mark Hopkins, cSixx has over two decades of experience developing innovative bicycle components, from carbon chainguides to CNC-machined chainrings, derailleur upgrades, stems and carbon handlebars.

Based at the foot of Table Mountain in Cape Town, we design, develop and manufacture our products in-house, combining engineering, precision machining and rider-driven development.

Design it. Machine it. Ride it. Repeat.

We make our parts in-house, start to finish - our cnc machines, our hands, our quality control. Nothing leaves the building until it meets our standard. When something can be better, that's how a part earns its place.

Parts Made For You

Beyond off-the-shelf bicycle components, we are developing a growing custom programme, allowing riders to personalise selected products with custom colours and laser-etched names. Built for riders who want their components to perform as well as they look.
