Some DURA-ACE and ULTEGRA 11 speed HOLLOWTECH II road cranksets with bonded construction manufactured prior to July 2019 have received warranty returns for bonding separation and reported falls and injuries. We want to ensure the safety of our customers by implementing this Crankset Inspection Program.

First validate if your crankset is part of the cranksets inspection program. Second, we ask you to take it to your local retailer to get inspected. 

Please refer to Shimano Authorized Crank Inspection dealer listing https://www.neozigmaph.com/inspection-store-list

ULTEGRA FC-6800, FC-R8000, DURA-ACE FC-9000, FC-R9100, and FC-R9100 P manufactured prior to July 2019.

Please work with your local retailer to submit. Shimano will be working with our retail partners to execute this process and that will allow for the most consistent tracking and overall levels of service.

To see if your product needs to be inspected, the model number and production code are stamped on the inside of the crank. Please refer to the announcement document for the location of this information.

Shimano will have any applicable crankset inspected by an authorized Shimano retailer.  Please visit the dealer locator for a Shimano dealer near you. Shimano will replace any cranks that fail the inspection process.

The new crankset uses the latest construction and bonding techniques. There will be slight cosmetic differences from the original crankset. In some cases the exact specification may not be available. 

" Cranks and or any Shimano products that are modified by 3rd parties are not covered by warranty, but as an exception they will be subject to this inspection.
Any crankset with a power meter that is found to fail during inspection and is sent back to Shimano will be replaced free of charge without the 3rd party power meter attached. 

However, an additional payment, based on the market average alongside the replacement crankset, can be used to purchase and mount a new power meter from a 3rd party onto a replacement crankset."

We encourage all riders to maintain their bicycle and riding equipment diligently.  Have your bike tuned up and inspected regularly (ask your retailer for recommendations based on your riding habits). Pay attention to changes in the sound and feel of how your bike is riding. Changes could indicate wear out, breakage, or need for adjustment to some part of your bike.

Shimano will do our best to expedite the replacement crankset. However, with all the different chainring and crankarm length combination we may not have your crankset in stock. If a replacement crankset is temporarily unavailable, Shimano will work with the retailer to communicate and confirm when the replacement is ready.

Yes. As a reminder, we recommend a general bike safety check before each ride (Tire Pressure, Quick Releases, and Basic Visual Inspection). In addition, if you feel a second inspection is needed, Shimano will provide this through your local authorized Shimano retailer. Due to the number of initial inspection, we ask that you wait at least 6 months for the second inspection unless you feel, hear, or see a change in your crankset.

In addition to recommending periodic inspections after the second inspection, we also provide information on how to conduct a self-inspection so that customers can check for themselves at the following URL.
