Claim Deadline
What You Need to Do to Get Paid
You may submit a Claim Form online at the official settlement website or by mail. The Claim Form must be submitted or postmarked by August 4, 2026. Documentation of the original purchase (or a declaration) and proof of replacement costs are required for reimbursement.
To receive reimbursement, you must submit documentation of the original purchase (receipt or photograph of the crankset) and documentation of the out-of-pocket costs for the replacement crankset and installation (receipts or invoices).
Settlement Payout
Settlement Class Members may receive reimbursement of reasonable out-of-pocket costs for purchasing a replacement crankset and installing it on their bicycle. This benefit applies if the Designated Crankset was replaced because it separated, delaminated, or exhibited evidence of delamination. Additionally, Shimano will automatically extend the Express Warranty for bonding separation and delamination until July 29, 2027.
Background of the Lawsuit
Plaintiffs alleged breaches of warranties and sought relief regarding the advertising and marketing of Shimano Hollowtech II cranksets and the alleged inadequacy of a voluntary recall initiated in September 2023. Plaintiffs claimed the cranksets were prone to bonding separation and delamination. Defendants deny any wrongdoing but agreed to settle to avoid the risk and cost of litigation.
