The hydraulic system became the mainstream brake system on road bikes, gravel bikes, and cargo bikes. Hydraulic brakes provide excellent power and control, but maintenance and installation can be difficult and requires specialist tools, plus the specifications of each brand are also different.

Our clever Q-Connector finally solves these problems for bikes with hydraulic discs. The Q-Connector allows instant, tools-free connecting and disconnecting of the bike’s hydraulic brake hose. The design allows for a perfect seal when disconnecting and no rebleeding of the brakes is required even after multiple uses. Sized to easily be integrated into the frame cable route.

Simply disconnect the brake system and just take off the fixed clip.
