Rebuildable

Built to be rebuilt and maintained as a mechanism that supports you for years. Easily serviced and adjusted with common tools. Adjust it, rebuild it, replace damaged parts, or change the configuration for a new drivetrain. On top of that, you will have access to the latest part update as the Jab evolves.

Durable

The Jab is precision machined from high quality materials like 6061 and 7075 aluminum and stainless steel. We apply a little bit of extra material and clever geometry in critical areas to ensure the assembly is stiff and durable. We also offer mounting options with an additional stiffener plate, which has similar strength and stiffness to "direct mount" derailleurs.
