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
  • Improved durability
  • Easier installation
  • Reduced size and weight

Can I also use SRAM GX or NX shifters?

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

How do I modify the SRAM shifters?

My crank touches the Hibox. What should I do?

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.

Do you offer OEM or dealer pricing?

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

Can I combine the Hibox C2 with mechanical brakes?

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/.

Can I combine the Hibox Trigger with Rohloff (Gebla Rohbox) ?

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