You may be part of a class action settlement — granted final approval on February 2, 2026 — reached with Shimano North America Bicycle, Inc., Shimano North America Holding, Inc., Specialized Bicycle Components, Inc., Trek Bicycle Corporation, and Giant Bicycle, Inc. over allegations that certain Hollowtech II road cranksets manufactured before July 2019 could experience bonding separation and delamination and that the voluntary recall and related warranties and marketing were inadequate.

What is the Total Settlement Amount?

The settlement allows reimbursement of qualifying out of pocket replacement and installation costs if you meet the conditions.How Do I Qualify For a Payout?

The included cranksets must have specific two-letter production (such as MF) codes listed on the official site and in the Long Form Notice. Reimbursement applies only if you replaced your Shimano crankset because it separated, delaminated, or showed evidence of delamination or separation and if other conditions below are met.
How Much Can I Get Paid?
The settlement provides reimbursement of reasonable out of pocket costs for buying a replacement crankset and installing it if you replaced due to separation or delamination and you qualify. There is no fixed dollar schedule. Your payment equals your documented costs that meet the rules. No cash is paid for the extended warranty benefit.How Do I File a Claim?
File online at the official settlement website or mail a completed claim form with documentation by the deadline. You must include proof of your replacement purchase and installation and that the replacement was because of separation or delamination.What is the Claim Form Deadline?

Documentation is required for your replacement purchase and installation and the reason for replacement. If you do not have proof of purchase available, you will be required to complete a declaration prior to submitting your claim, and in certain cases you may be asked to provide some documentation such as a photograph together with your attestation.

• Replacement Crankset Make and Model
• Invoice or receipt for replacement crankset and/or installation costs, including purchase date

Again, the Shimano crankset class action settlement website states that if you cannot provide the required documentation, you must complete a declaration under penalty of perjury before submitting your claim.
