If your e-muli is equipped with belt drive, it replaces the usual chain. The belt
is lighter than chain and requires signicantly less maintenance. It runs almost
noiselessly and with more smoothness than chain, is insensitive to rust and
strong sunlight.
The belt does not need and should not be oiled or lubricated. Due to its carbon
ber surface, dirt does not stick to the belt. If necessary, it can be cleaned with
water and soft brush.
The durability of the individual components of the Gates Carbon Drive System
strongly depends on external influences and environmental conditions. Therefo-
re, check the condition of the belt regularly.
Belt tension
When tensioning the belt, proceed in the same way as when tensioning the chain.
Take look at the photos there for the following steps for better understanding.
1. To tension the belt, loosen the two M6 Allen screws on the dropout mount with
5 mm hex wrench. Open the screws on the left and right side.
2. Then use 2 mm hex wrench to turn the grub screw in the dropout and push
the dropout backwards until the correct belt tension is achieved.
3. the line markings on the dropout will help you determine the same dropout
position for the right and left sides.
4. When the belt is taut and the two dropouts are in the same position, tighten
the two cap screws on the dropout mount.
You can determine the correct belt tension using the Gates Carbon Drive™ mo-
bile app. This app is available free of charge for Android devices and IPhones.
