FITTING THE CHAINRINGS ON TO THE CRANKSET (cont.)
Checking how the chainrings have been fitted:
When you fit the chainrings, check:
- The orientation of the chainrings so that the gears change correctly.
- The position of the chain's anti-skip cone on the exterior chainring in order to avoid the chain
becoming stuck between the chainring and the crank. The chain's anti-skip cone must be behind the
crank.
Attention :
LOOK recommends the use of its specific chainrings for the ZED crankset for the following reasons:
- The specific shape of the teeth on each LOOK chainring, which facilitates the gear changes, was
developed to respond to being fitted to the double and/or compact ZED star.
- The strength and rigidity of the LOOK chainrings have been optimised particularly thanks to a
larger support surface where each branch is attached.
