Frequently Asked Questions

What fits with Cube Reaction?

Cube Reaction is compatible with forks, seatposts, wheels, bottom brackets that match its technical standards. Most importantly, it requires matching speed components.

Can I mix Cube Reaction with Road components?

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