The Shimano Nexus Inter 5E is one of the most reliable internal geared systems for e-bikes, and for this reason, many top-tier brands have incorporated its technology.
This tech type is generally seen in bikes that have a belt-drive configuration (but not necessarily), and are operated sometimes via a twist shift system or a standard shifter configuration like the one used in the Orbea Diem 20 e-bike.
If you are unsure about how to tune the Nexus Inter 5E, I will guide you step-by-step on what to look at and what to consider when tuning it.
Nexus Inter 5E Specs (basic)
- Model SG-C6000 and C7000
- 5-speed system
- It is compatible with a belt-drive configuration
- 27-tooth gear, which should match with a 38-tooth front plate
- There are two shifting options: mechanical and electric (also called Symphomatic Di2)
- Specifically created for electric bikes due to the additional torque and pedal strain.
- The gear can be dropped in a static position without generating stress on the system.
How to Tune the Shimano Nexus Inter 5E?
At first glance, it appears complex, but it is very simple. This is how you can do it yourself:
- Go to the geared hub and locate the two yellow lines (sometimes they are red). They can be seen by looking at the little window, which is located between the hub and the frame.
- If you see one yellow line only (not two), go to the shifter system and change the gear selection until reaching gear 3 (see disclaimer below, please).
- Go back to the Nexus Inter 5E; the two yellow lines should now be present.
- If they don’t look aligned, you will need to move the adjusting wheel located at the gear lever (back again).
- By rotating it backward or forwards, you will notice the second yellow line (on the frame end) will move in front of or behind the primary yellow line (on the hub end). Backward will move it in front of the primary yellow line.
- Once the two lines are aligned, the Inter5E is fine-tuned.
Disclaimer: This method is applicable for the microShift gear system. Gear 4 is for the twist configuration.
This method works similarly for other Nexus geared hub systems; make sure you select the right gear to have both lines present.
The Nexus Inter 5E Di2 Configuration: Automatic Shifting
Shimano has gone further with their tech and is also offering an automated hub system. I haven’t tested one myself, yet, but the manufacturer claims that riding times are reduced and the pedalling efficiency is increased.
This intelligent Symphomatic Di2 detects the rider’s cadence, riding style, and terrain inclination to provide the proper gear selection for the best experience.
I cannot advise if the automatic gear adjustment will be the same as explained above; however, I’ll update this guide when I get to review it.

Final Thoughts
Shimano is offering a new level of riding experience and efficiency.
I believe the Shimano Nexus Inter 5E geared hub system (and following models) is quite simple to operate, and very smooth when shifting. This, of course, can be experienced if the system is tuned correctly.
