Service Information:

This SERVICE BULLETIN provides instructions for the MOTERRA bikes chain ring lock ring to be proactively replaced. The upgraded lock ring is identified with a “V2” laser etching on the side. This operation can be performed by Authorized Cannondale dealers.

Cause of the Replacement:

The current lock ring may develop lateral play over time with the chain ring. The consequence of this play will be including a premature wear on the axle due to a lack of torque.

Required Action:

We are asking Cannondale Dealers to perform a proactive replacement of the chain ring lock ring equipped on these bikes.

The given recommendation from our owner manual supplement requires a 1000 km maintenance; this service bulletin is to replace the lock ring before the required standard maintenance. The “old” lock ring should not be used anymore and scrapped.

Bike material codes:

This bulletin affects all MOTERRA bikes shipped from CSG until

31/01/2017.
