Service kit for HOPE X2 brake
Big respect to Hope Tech for releasing their official service tool designs to the public. These tools are engineered specifically for maintaining E4, GR4, RT4, RX4+, V4, and X2 brakes, allowing for precision piston service without risking damage to the caliper finish. In the spirit of a true technical partnership with the riding community, we want to make sure every rider has access to these essential workshop aids.
Important note: These are open-source designs by Hope Tech. If you don’t have a 3D printer, we are here to print them for you.
Not a VisionVelo Original Product
Important Note: These tools are not designed by VisionVelo. We are not the authors of these projects; we are simply providing a high-quality manufacturing service for those who do not own a 3D printer. We believe in the right to repair, and we’re happy to utilize our industrial-grade machines to help you keep your Hope brakes in peak condition.
Print It Yourself or Let Us Handle It
If you have access to a 3D printer, we highly encourage you to download the files and print them yourself! You can find the official open-source resources directly on the Hope Tech Website.
However, if you lack the equipment or want a professional-grade result, we offer this printing service.
