Jab Derailleur

Each Jab is assembled to order by a small team of experienced technicians. It can take anywhere from 2 to 5 business days to ship out, depending on how many orders we have. We are focused on quality over speed, and are grateful for your patience! We are stoked to introduce Madrone's very own Jab derailleur, named after the iconic Jabberwocky trail here in Ashland, Oregon! The Jab is a cable actuated derailleur built for all types of 1x bikes - MTB, gravel, and e-bikes. Whether you’re replacing a tired derailleur or building a new ride, the Jab is designed to integrate seamlessly into a variety of different 1x drivetrains. Compatible: Flawless shifts with common 1x drivetrains - MTB or drop bar, 12 or 11 speed, and robust mounting options. You can learn more about compatibility here. Jab Cam Options Jab Mounting Options Jab Cage Options 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. You can also send it in any time for a professional rebuild by Madrone, for a flat rate of $85 + shipping. On top of that, you will have access to the latest part update as the Jab evolves. Durable: Regarding durability-to-weight, the Jab leans toward durability without going too far. Most parts are CNC machined 6061 and 7075 aluminum (compared to a mix of die cast aluminum and plastic used by competitors). 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. Accessories: Hanger for T-Type Cassettes Alternate cams. Replacement parts can be found here.
