Shimano Crankset Recall Class Action Settlement

People in the U.S. who owned a covered Shimano Hollowtech II road crankset made before July 2019 (Ultegra FC-6800/R8000, Dura-Ace FC-9000/R9100/R9100P) with a qualifying production code, and replaced it because it separated or delaminated. Includes bikes from Specialized, Trek, and Giant.

• Owned a covered Shimano Hollowtech II road crankset made before July 2019 with a qualifying production code
• Replaced it because it separated, delaminated, or showed evidence of it (for reimbursement)
• Provide receipts for the replacement and installation; a sworn declaration may substitute where documentation is unavailable

A settlement (final approval granted February 2, 2026) was reached with Shimano North America, Specialized, Trek, and Giant over allegations that certain Hollowtech II road cranksets manufactured before July 2019 could experience bonding separation and delamination, and that the voluntary recall, warranties, and marketing were inadequate. The settlement reimburses qualifying out-of-pocket replacement and installation costs, automatically extends Shimano's express warranty for bonding separation/delamination through July 29, 2027, and keeps the dealer inspection program from the 2023 recall open (free inspection, and a free replacement crankset if separation or delamination is found).

Who's excluded: Reimbursement applies only if you replaced your crankset because it separated, delaminated, or showed evidence of it. Covered cranksets must have specific production codes listed in the long-form notice. No cash is paid for the warranty benefit. Opt-out/objection deadlines (Dec 29, 2025) have passed.

• Reimbursement of replacement + installation

  Reimbursement of reasonable documented out-of-pocket costs to buy and install a replacement crankset, if you replaced due to separation or delamination. No fixed dollar schedule — you're paid your qualifying documented costs.

• Extended warranty — automatic

  Shimano's express warranty for bonding separation/delamination is automatically extended through July 29, 2027 — no claim form needed.

• Free dealer inspection / replacement

  The 2023-recall dealer inspection program remains open: free inspection at authorized retailers, and a free replacement crankset if separation or delamination is found.
