On September 21, 2023, Shimano Industries, Inc., a Japanese multinational manufacturing company for cycling components, fishing tackle, rowing equipment, and other sporting equipment, issued a recall for 760,000 11-speed Hollowtech road cranksets. The cranksets were manufactured in Japan and sold individually or on bicycles by other manufacturers in bicycle retail stores like Trek and Specialized nationwide from January 2012 through August 2023 for between $270 and $1,500. 

According to the report posted by the U.S. Consumer Product Safety Commission (CPSC), the recall comes after the company received reports of 4,519 incidents of certain 11-Speed Bonded Hollowtech Road Cranksets models separating. Six of the reported users suffered injuries that included bone fractures, joint displacement, and lacerations. For safety reasons, customers who own one of the recalled cranksets are asked to immediately stop all use and contact their local Shimano dealer.

The affected models include the DURA-ACE and ULTEGRA branded cranksets with the model numbers DURA-ACE FC-9000, DURA-ACE FC-R9100, DURA-ACE FC-R9100P, ULTEGRA FC-6800, and ULTEGRA FC-R8000. The affected models involve those made before the July 2019 production, with the ‘Ultegra’ or Dura Ace logos printed on the arm. The cranks also come with a two-letter production code on the backside of the crank arm where the pedals are attached. The codes included on the cranks are as follows:

Customers who are struggling to identify if they are in possession of one of the recalled cranks should speak with an authorized Shimano retailer or contact Shimano toll-free at 844-776-0315 from 8 a.m. to 5 p.m. PT Monday through Friday or online at or head to their company website and click “Information” then “Safety Recalls” at the top of the page for more information.

How You Can Register for a Replacement Crankset

Shimano consumers with cranks with production codes that match the recall are instructed to immediately stop all use of the cranksets and to head to their nearest bike dealer for an inspection. However, the company believes fewer than 1% of the inspected cranks will require replacement. Those consumers with cranks that show signs of bonding separation or delamination will be given a replacement crank and installation. 

Shimano says they anticipate that the inspections will be possible starting from October 1, 2023, and the replacement cranks will start shipping the week of October 10, 2023. The company said it will ship the replacement cranks to retailers after they receive the old crankset and confirm it is eligible for replacement. The company also said they are reserving the option to return cranks that it does not deem eligible for replacement.

Customers should keep in mind that due to the different chainring and crankarm length combinations, certain cranksets may not be in stock. However, when in stock, the replacement cranksets process will take up to 10 days. If a replacement crankset is temporarily unavailable, Shimano will work with local retailers to communicate and confirm with customers when the replacements are ready. 

Shimano customers can find more information on the recall provided by the U.S. Consumer Product Safety Commission under the number 23-294. For more details behind the 11-Speed Bonded Hollowtech II Road Cranksets recall, or if you have suffered an injury, contact a Morgan & Morgan attorney today.
