With our dedication to safety and quality in mind, Shimano is issuing a voluntary recall of some bonded 11-speed HOLLOWTECH II road cranksets produced before July 2019 for a possible bonding separation issue.
To remedy this situation, Shimano will have applicable, pre-July 2019, cranks inspected by Shimano authorized retailers and Shimano will replace any cranks that fail the inspection process. There is no need for further action for cranks that pass the inspection process. The CPSC has reviewed and approved the voluntary Corrective Action Plan that Shimano has proposed. This is designed to give the consumer multiple ways to determine whether their crank shows a possible bonding separation issue and to swiftly remove any possible safety hazard to our consumers.
Not all Ultegra and Dura-Ace cranks need to be inspected. Only cranks produced before July 2019 need to be inspected, and the way to know if your crank should be inspected is to identify it in step 1 below.
Crank Identification and Inspection Process
Step 1 - Determine Whether this notice applies to your crankset
Step 1A - Identify the model number of your crankset
The affected model numbers are DURA-ACE and ULTEGRA branded cranksets with the following model numbers: ULTEGRA FC-6800, FC-R8000 and DURA-ACE FC-9000, FC-R9100 and FC-R9100-P. The model numbers are stamped on the inside of the crank arm near the bottom of the arm (see yellow square in the] image below)
- Does the model number on your crank arm match the model numbers above
- NO: The crank is not affected, and no further action is needed.
- YES: Proceed to STEP 1B.
Step 1B – Identify the production code stamped on your crank arm (blue box on the image below)
- A production code is stamped on the inside of the crank arm near the bottom of the arm. The affected models are pre-July 2019 production and have the following two-letter production code on backside of the crank arm where the pedals are attached: KF, KG, KH, KI, KJ, KK, KL, LA, LB, LC, LD, LE, LF, LG, LH, LI, LJ, LK, LL, MA, MB, MC, MD, ME, MF, MG, MH, MI, MJ, MK, ML, NA, NB, NC, ND, NE, NF, NG, NH, NI, NJ, NK, NL, OA, OB, OC, OD, OE, OF, OG, OH, OI, OJ, OK, OL, PA, PB, PC, PD, PE, PF, PG, PH, PI, PJ, PK, PL, QA, QB, QC, QD, QE, QF, QG, QH, QI, QJ, QK, QL, RA, RB, RC, RD, RE, and RF. Please proceed to Step 2 if your crank has this code. If your crankset does not have one of these codes, please proceed to step 3.
- If you have noticed any changes in the feeling of the crank when you pedal or hear noise or creaking, please proceed to Step 2.
- Consumers who believe they have an applicable product or are unsure how to check the manufacturing code are asked to contact an authorized Shimano retailer to schedule a free crankset inspection. Please see below for instructions on how to figure that out. You may also call us at (844) 776-0315 for assistance.
- Consumers with cranksets that do not fall within the specified date codes do not need to take further action regarding this safety recall or inspection.
- Please proceed to Step 3.
Step 2 - Take the bicycle to the retailer for inspection
Shimano has developed the crank inspection process and will provide clear instructions and tutorials for retailers.
- You can take your bike to a participating retailer starting October 1st
- The retailer will inspect the crankset for signs of bonding separation or delamination.
- Retailers will submit the required information to Shimano so that we can document the inspection, results, and replacement cranks if needed.
- Shimano is required to maintain this information for CPSC reporting and to ensure the process is completed.
- Consumers whose cranksets show signs of bonding separation or delamination during the inspection will be provided a free replacement crankset* from Shimano that the retailer will professionally install.
Step 3 – Ride safely and continue to inspect your bicycle/equipment
If your crankset passes the inspection and has no signs of delamination, we appreciate your patience and diligence in having the safety inspection done. You may continue using your crankset as normal.
- If your crank requires replacement, we appreciate your patience to complete this process.
- 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.
- If a replacement crankset is temporarily unavailable, Shimano will maintain a registry of retailer requests and will notify retailers when the replacement is ready.

Frequently Asked Questions
Q:
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 voluntary inspection and recall program.
First validate if your crankset is part of the recall. Second, we ask you to take it to your local retailer to get inspected. Retailers can be found at our Dealer Locator and the retailers who have opted into this inspection process will be flagged on our dealer locator as an inspection location.

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 www.bike.shimano.com and click on 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 items that are found to fail during inspection and that are sent back to Shimano will be replaced free of charge without the 3rd Party Power Meter attached. Shimano will be providing a rebate in the form of a check to the consumer where the consumer can use that towards the replacement of the 3rd party power meter.
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.
No. Retailers who wish to be part of our inspection campaign will opt into the program. We will highlight these dealers in the dealer locator. If your local retailer is not listed, please call them to validate if they are participating in the program.
Please note that this will be in addition to a retailer’s normal workload, and they may not be able to complete this inspection right away. Your local retailer can advise on their current workload and estimated turnaround times to inspect your crankset.
Yes. As a reminder, we recommend a general bike safety check before each ride (Tire Pressure, Quick Releases, and Basic Visual Inspection).
For your safety, Shimano will provide the initial and second inspection free of charge through an Authorized Shimano Retailer.
We recommend that the second inspection be performed about one year after the initial inspection. If you feel, hear, or see a change in your crankset, please take it to an Authorized Shimano Retailer at any time.
