Shimano crankset recall class action settlement
What Is the Shimano crankset settlement about?
This lawsuit alleges that certain Shimano Hollowtech II cranksets manufactured before July 2019 were defective due to potential bonding separation and delamination. Plaintiffs also claim that Shimano’s voluntary recall was inadequate and that consumers were not properly informed about the risks.
Shimano and the other defendants deny the allegations but agreed to a settlement to avoid the cost and uncertainty of further litigation.
How much Is the Shimano crankset settlement payout?
If you're eligible and file a claim, you may receive a cash reimbursement for the reasonable, documented out-of-pocket costs you incurred when replacing a Designated Crankset that exhibited separation, delamination, or evidence of delamination.
The settlement payout varies based on:
- The documented cost of the replacement crankset
- Installation charges paid out-of-pocket
- Whether the crankset was replaced before September 21, 2023
- Whether the original Express Warranty had expired at the time of replacement
- The number of valid claims submitted
The settlement also includes non-cash benefits such as an extended warranty through July 29, 2027 and enhanced inspection processes.
Am I eligible to file a claim?
You may be eligible to submit a claim if:
- You purchased, received, were given, and/or owned a Designated Shimano Crankset in the United States,
- Or you owned a bicycle equipped with a Designated Crankset
- And you did not purchase the crankset solely for resale.
Eligible Designated Cranksets include:
- Ultegra FC-6800
- Ultegra FC-R8000
- Dura-Ace FC-9000
- Dura-Ace FC-R9100
- Dura-Ace FC-R9100-P
These must have production codes listed in the official notice (e.g., KF, KG, LA, MB, NB, OC, OD, PE, PF, QH, QI, RA, RB, and many more).
You do not need to submit a claim to receive the extended warranty—it is applied automatically.
