Shimano Defective Crankset Settlement
Court case: In re Shimano Crankset Litigation
If you own or owned a specific Shimano Hollowtech II crankset (Ultegra FC-6800, FC-R8000, Dura-Ace FC-9000, FC-R9100, or FC-R9100-P made before July 2019), a class-action settlement gets you a free extended warranty and inspections. If you already paid to replace a crankset after the original warranty expired, you can file for reimbursement. The deadline to file a claim is August 4, 2026.
Official eligibility wordingIf you purchased, received, were given and/or owned a Designated Crankset (Shimano Hollowtech II Ultegra FC-6800, FC-R8000, Dura-Ace FC-9000, FC-R9100, or FC-R9100-P manufactured before July 2019 with specific production codes KF through RF) or a bicycle equipped with such a crankset in the United States, you may be eligible to receive benefits.
Key facts

- Estimated payoutSettlement provides extended warranty (no cost), free enhanced inspections at authorized retailers, and reimbursement of reasonable out-of-pocket costs for replacement and installation for those who replaced cranksets before September 21, 2023 after original warranty expired.

Important dates
How hard is this claim to file?
Watch out for
- Reimbursement is only on the table if you replaced the crankset before September 21, 2023 and the original Shimano warranty had already expired by then. Replaced it after that date, or while it was still under warranty? No cash back.
- There's no settlement cash pool here. The core benefits are the extended warranty and free inspections. Reimbursement applies only to that specific pre-September 2023 replacement window.
- You'll need to physically check the production code stamped on the component. It has to land between KF and RF — no code, no eligibility confirmation.
We prepare — you file on the official site yourself. This is not legal advice and is not an eligibility decision; the administrator and court decide.
