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.

• Larger gear wheel → less dead travel
• Increased module size
• Improved durability
• Easier installation
• Reduced size and weight

Yes, but with limitations:

• You can only shift one gear at a time
• You'll need both a left and a right shifter
• The shifters need to be modified

Older CNC-machined Pinion cranks can sit very close to the HIBOX and may touch it. According to our experience as a dealer, forged Pinion cranks are not affected. Correct axial crank positioning according to Pinion’s instructions is essential.

1. Tighten the centre screw to 10 Nm.
2. The remaining 1–2 mm of axial movement on the input shaft is normal and no reason for concern.
3. Pull the crank fully outward to the stop.
4. Then tighten both clamp screws alternately and in stages to 6 Nm each.

This positions the crank correctly and maximises clearance to the HIBOX.

Yes, we do. Please send us an email, and we’ll upgrade your account to a dealer account.

Yes, absolutely! It works with SRAM mechanical shift-brake levers (brifters) without any extra parts — just a small modification is needed. The required steps are explained in detail at: gebla.de/.

No, the use with Gebla Rohbox is not recommended and its getting uncomfortable over the time, due to much higher shift forces needed.

Hibox FAQ: Compatibility, Shifters & Installation

Hibox for mechanical Pinion gearboxes

These FAQs cover compatible shifters, modifications and installation of Hibox. C2 is designed for the Pinion C-Line; P1 is designed for the P-Line. Check your exact gearbox and shifter model before ordering.

Can I order Hibox P1 or C2 with different brake calipers?

Yes, of course. We can adapt your Hibox P1 or C2 brake/shift lever set to suit your bike if you need different calipers from those listed in the selected option — for example, Post Mount instead of Flat Mount, or 2-piston or 4-piston calipers, or different calipers for the front and rear.

Simply send us a short message at info@hilite-bikes.com with your selected Hibox set, brake/shift lever model and the calipers you would like for the front and rear, ideally including the exact model numbers. If you have already ordered, please include your order number. We will confirm the suitable combination, take your request into account and send you an updated invoice reflecting any price difference.

2-piston or 4-piston brake calipers: what is the difference?

2-piston calipers have one piston on each side of the rotor; 4-piston calipers have two on each side. Four-piston models generally provide more braking power and suit demanding descents and heavier loads. The actual braking performance also depends on the lever, rotor size and pads. Flat Mount and Post Mount describe the mounting standard, not the number of pistons.

You can also request 4-piston calipers at the front and 2-piston calipers at the rear. Tell us your preferred setup; we will check the exact lever, caliper, hose and rotor combination before confirming your set.

Which cable housing end caps do you recommend for Hibox?

For Hibox P1 and C2, we recommend unsealed shift cable housing end caps (ferrules). In our workshop experience, these noticeably reduce the force required to operate the shifter and help the cables move more freely.

Sealed end caps have an additional seal around the inner cable to help keep dirt and moisture out. This seal also adds friction. For the lightest possible Hibox shifting action, we therefore recommend avoiding sealed versions, such as Shimano’s sealed plastic end caps for SP40/SP41 shift cable housing, and using suitable unsealed end caps instead.
