HIBOX P1

Revolutionizing mechanical gear shifting for Pinion

The Hibox P1 redefines what's possible with Pinion drivetrains – offering true integration with race bar brake/shift levers or trigger shifters on flat bars. Whether you're racing, touring, or bikepacking, the Hibox unlocks seamless shifting with the ergonomic controls you already love – no more bulky twist shifters or tangled cockpit cables.

Designed specifically for Pinion P-Line gearboxes, the Hibox P1 allows you to shift with familiar Shimano or SRAM levers on both drop bars and flat bars. Shift up on the left and down on the right – or vice versa. Each press shifts one gear, and you can even shift while coasting or pedaling backward.

The Hibox P1 is fully compatible with the Hibox Trigger Shifter, but also supports modified brake/shift levers from most major brands. It delivers a clean cockpit, a natural riding feel, and the full performance potential of your Pinion drivetrain.

Features:

  • Compatible with Shimano & SRAM brake/shift levers

  • Left/right independent shifting on drop-bar– 1 gear per press

  • Supports trigger shifters and drop-bar setups

  • Improved shift performance versus Hibox C1 ~30%

Which drop bar shifters do you recommend?

Shimano and SRAM both work well. Shimano shifters require less force when shifting from the hoods, while SRAM has a shorter lever throw when shifting from the drops. It depends on your preference.

What has been improved from Hibox C1 to Hibox C2?

  • Larger gear wheel → less dead travel
  • Increased module size

Can I also use SRAM GX or NX shifters?

Yes, but with limitations:
