Maintenance
• If you increased the shift cable clearance to make it easier to remove the rear
wheel, you will need to readjust it now.
6.7. Adjusting the NuVinci gear hub
The gear shift quality of the NuVinci gear hub may decrease while the vehicle is in
use. You can correct this by adjusting the shift cable clearance.
• You can feel the shift cable clearance by gen-
tly pulling on the end caps of the gear cables
that run into the twist grip.
• A clearance of 0.5 mm per pull is ideal. More
than 2 mm clearance can adversely affect the
gear shift quality of the system and the ser-
vice life of the shift cable.
• To adjust turn both setscrews and check the
amended clearance.
0,5 mm
6.8. Brakes
As it is a hydraulic braking system, your maintenance options are limited. Work on
the hydraulics should be carried out by HNF-NICOLAI Service or a bicycle workshop.
In any case, please contact HNF-NICOLAI Service or a bicycle workshop if the pres-
sure point of the brakes fluctuates.
6.8.1. Brake pad and brake disc wear
Brake pads and brake discs are subject to functional wear caused by friction
between the two parts. The wear depends on the riding style, terrain, weather and
ground conditions, meaning that no binding information can be given regarding the
brake pads.
Brake discs need to be replaced after approx. 4 to 5 changes of brake pad pairs,
as they are made of a harder material. It is recommended to check the brake pads
every 500 km.
