Frequently Asked Questions

What fits with Shimano GRX SUB BRAKE LEVER?

Shimano GRX SUB BRAKE LEVER is compatible with brake calipers, front derailleurs, rear derailleurs that match its technical standards. Most importantly, it requires matching speed components.

Does this Shimano GRX SUB BRAKE LEVER work with electronic shifting like Di2 or AXS?
