MTB/ ROAD BIKE/ TREKKING
When using an electronic derailleur
gear (called Di2 by Shimano), the shif-
ting is done by pressing buttons.
The Di2 connection is analog.
For further information, please refer
to the specic operating instructions
provided by the manufacturer.
On derailleur systems the gear is shifted
by switching the chain to another sprocket
On the crank set these sprockets are called
„chain rings“ and on the rear sprocket
cassette they are called „pinions“.
3. Please observe the chain position
prescribed as shown above.
•
To be avoided:
Largest chain ring + largest pinion.
•
Smallest chain ring + smallest pinion.

Shimano Rapidre
Sram Force / Rival / Red
Shimano STI
The STI connection is mechanical.
The left-hand lever operates the chain
ring derailleur and the right-hand lever
operates the gear shift.
