Description
• PINION COMPATIBLE 10 AND 11 SPEEDS
The specific production of the sprockets is intended for use with 10 and 11-speed chains.
•DESIGN AND STIFFNESS TAILORED TO ZED BOTTOM BRACKET
The design of the large sprocket is perfectly adapted to the chainring star of the ZED system. It gives the chainring excellent rigidity to eliminate any energy loss. For this reason, the pinion has 5 mounts that ensure perfect adhesion between the teeth and the pinion's adhesion points.
• EXTREMELY LIGHT PINIONS
Despite the monoblock aspect and the wide mounts, the large sprocket is extremely light (92 g with 52 teeth). The reason for this is the CNC technology on the inside of the wing, which forms a kind of coating and ensures rigidity without additional weight.
• 4 AUXILIARY ELEMENTS FOR RISING THE CHAIN
The large sprockets have 4 devices that engage when the chain is moved to ensure quick and precise gear changes.
WEIGHT: 92 GRAMS WITH 52 TEETH / 46 GRAMS WITH 42 TEETH
• 10 AND 11 SPEED COMPATIBLE CHAINRINGS
The chainrings are specially machined to be used with 10 and 11 speed chains.
• MATCHING DESIGN AND RIGIDITY
The design of the large chainring is simplified because it almost completely disappears behind the crankset and is optimized to offer greater rigidity. This is also the reason why they are machined in 5 mm thick aluminum plates instead of the usual 4 mm.
• CNC MACHINED CHAINRINGS
The manufacturing technology is CNC machining. This allows greater accuracy in chain up and down shifting ramps providing silent operation and quick, silent gear changes.
• CHAINRING PAIRS
Chainrings are sold individually but are made to work as pairs. In fact the machining on the large rings differs and is optimized to work with a very specific small ring. By following this recommendation you will be sure of optimal operation. The following teeth numbers are available:
