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 optimised to offer greater rigidity. This is also the reason why they are machined in 5 mm thick aluminium 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 singly but are made to work as pairs. In fact the machining on the large rings differs and is optimised to work with a very specific small ring. By following this recommendation you will be sure of optimum operation. The following teeth numbers are available:

• 53 for 39
• 52 for 39
• 52 for 36
• 50 for 36
• 50 for 34
• 39 for 52/53
• 36 for 50/52
• 34 for 50
