Frequently Asked Questions

What fits with RockShox Judy?

RockShox Judy is compatible with brake calipers, wheels, frames, headsets that match its technical standards. Most importantly, it requires matching speed components.

Can I mix RockShox Judy with Road components?

While some mechanical standards (like cassette spacing at certain speeds) may overlap, RockShox Judy is optimized for MTB use. Mixing with Road parts often fails due to differing pull ratios and chainlines.
