Introducing the '12mm Spindle Kit - Universal,' the essential solution to change Grom/Z125/Pitbike tires with the Rabaconda Street Bike Tire Changer. This kit serves as the culmination of multiple iterations, ensuring a refined and top-notch product that seamlessly allows your existing Rabaconda SBTC to also change tires with a 12mm axle. *This does NOT include the Rabaconda SBTC. This is ONLY an accessory for the machine*Consider it the finishing touch to an already impressive portable manual tire changer. Prior experience with the original spindles is recommended (but not required if you read the instructions from Rabaconda closely) before transitioning to the '12mm Spindle Kit - Universal'. It's important to note that using excessive force on the spindle incorrectly will lead to bending. Rest assured, if a spindle does happen to bend accidentally, use that as your marker to understand that you are using the machine incorrectly. We have chosen a material that will be okay with bending and being bent back multiple times. If you continue, you bend the spindle. I'd highly suggest practicing with larger wheels to get the technique down before attempting the more difficult smaller spindle again. Individual components are available for replacement. STOP immediately if a bend occurs due to excessive force and refer to the instructional video. This kit includes 4 essential items: 12mm Spindle: The result of multiple iterations, this spindle is the backbone of the kit. Refined for durability and longevity, we spared no cost in the materials and design.   Duck Head Reducer: This is the aluminum reducer/sleeve that slides into the ratcheting mechanism from Rabaconda. Taking up the space between the ratchet and the spindle in a similar way to their 15mm kit. Grom Wheel Spacer + Washer Kit: Originally designed for all Grom wheels, this spacer goes in between the wheel
