A US court has granted final approval of the settlement in the class action case over the Shimano Hollowtech II cranksets that were recalled in 2023.
The preliminary settlement was agreed between the plaintiffs and Shimano in July 2025, and has now been approved by the court, Shimano said in a statement published yesterday.
The deal covers US owners of Shimano Dura-Ace and Ultegra cranksets manufactured before 2019, and sees Shimano extend its “express warranty” for bonding and delamination to 31 July 2027.
Shimano will now distribute a magnifying device with enhanced lighting to every recall retailer “free of charge”, alongside a manual, and the retailers must “affirm that they have reviewed and will utilize all materials provided by Shimano related to the Inspections”.
US riders affected by the recall can now submit reimbursement claims on Shimano’s dedicated website.
The lawsuit was filed against Shimano, Specialized and Trek soon after Shimano issued the recall of more than 760,000 cranksets in North America and 2.8 million globally.
The United States Consumer Product Safety Commission (CPSC) said the recall applied to cranks sold over an 11-year period, from January 2012 through August 2023, after a reported 4,519 incidents of cranksets separating. According to the CPSC, the incidents resulted in six injuries, including bone fractures.
BikeRadar first reported on Shimano road cranksets delaminating in 2020, but the 2023 recall was the first time Shimano acknowledged a widespread issue with its cranks.
Shimano’s statement, released yesterday and translated from Japanese, said: “The impact of this settlement on the Company’s future business performance is expected to be immaterial. Should timely disclosure become necessary in the future in accordance with relevant laws and regulations, we will promptly make the appropriate disclosure.”
