If you paid out of pocket to replace a defective Shimano Hollowtech II crankset before the September 2023 recall, you have until August 4, 2026 to file a reimbursement claim through the official settlement website at ShimanoCranksetSettlement.com. A US federal judge granted final approval of the class action settlement on February 5, 2026, following a preliminary deal reached in July 2025, and the clock is now ticking for cyclists who want their money back. Consider a road cyclist who noticed their Dura-Ace FC-R9100 crankset delaminating in 2021 — two years before Shimano issued any recall — and paid a bike shop several hundred dollars for a replacement out of their own pocket.
That rider is exactly the type of class member this settlement was designed to compensate. But the reimbursement window is not open-ended, and there are specific eligibility rules that could disqualify certain claims entirely. We also cover the automatic extended warranty benefit that requires no action on your part, and the enhanced inspection program Shimano must now fund at recall retailers.

What Is the Shimano Crankset Settlement and Why Does the August 4, 2026 Deadline Matter?
The settlement resolves *In re shimano Crankset Litigation*, a class action lawsuit alleging that Shimano’s Hollowtech II cranksets could separate or delaminate during rides, creating a serious crash hazard. The original CPSC recall in September 2023 covered approximately 760,000 cranksets sold in the United States. However, the recall alone did not compensate riders who had already spent their own money fixing the problem before free replacements became available — that is what this settlement addresses. The August 4, 2026 deadline is specifically for submitting documented reimbursement claims to the Settlement Administrator. This is not the deadline for the extended warranty or the inspection program — those benefits operate on separate timelines.
If you miss August 4, 2026, you forfeit your right to recoup what you spent on replacement parts and labor. Unlike some class action settlements where the deadline gets extended multiple times, there is no guarantee that will happen here, so treating this date as firm is the safest approach. To put this in perspective, compare it to a typical consumer product recall. In most recalls, the manufacturer simply replaces the defective part at no cost going forward — end of story. This settlement goes further by reaching back to cover people who paid for fixes before the recall existed. That retroactive reimbursement is the piece with the hard deadline.
Which Shimano Crankset Models Are Covered Under This Settlement?
The settlement covers specific Shimano Hollowtech II cranksets manufactured before July 2019. On the Dura-Ace side, the affected models are the FC-9000, FC-R9100, and FC-R9100-P, all 11-speed components. For Ultegra, the covered models are the FC-6800 and FC-R8000, also 11-speed. If your crankset is not on this list — say you have a 105-level component or a 12-speed Dura-Ace — you are not part of this class. One important limitation: simply owning an affected model does not automatically entitle you to a cash reimbursement.
The reimbursement is only for people who actually paid to replace the crankset. If your crankset is still installed and functioning, the benefit you receive is the extended warranty, which covers bonding separation and delamination issues through July 29, 2027. That warranty extension is automatic and requires no claim form. However, if you purchased a used bike equipped with one of these cranksets and later paid for a replacement, your eligibility may depend on whether you can document the original retail purchase. The settlement requires documentation of the original retail purchase along with supporting documents for the reimbursement request. Riders who bought secondhand and lack a paper trail should still check ShimanoCranksetSettlement.com for specific documentation requirements, as the settlement administrator may accept alternative forms of proof.
Who Is Not Eligible for Reimbursement — The Restrictions That Could Disqualify Your Claim
Not everyone who replaced a defective Shimano crankset can collect reimbursement, and the eligibility restrictions are worth reading carefully before you spend time assembling a claim. First, if your crankset was replaced on or after September 21, 2023 — the date Shimano launched its recall — you are not eligible for reimbursement. The logic is straightforward: once the recall was active, free replacements were available, so there was no need to pay out of pocket. Second, if the Express Warranty had not yet expired at the time you replaced the crankset, you are also ineligible.
Shimano’s original warranty periods were two years for Ultegra models and three years for Dura-Ace models, measured from the date of original retail purchase. So if you bought a Dura-Ace FC-R9100 crankset in January 2020 and replaced it in December 2021 — less than three years later — the warranty should have covered it, and the settlement will not reimburse you for that replacement. Here is a concrete example of someone who would qualify: a cyclist who purchased an Ultegra FC-6800 crankset in 2016, noticed delamination in 2020 (well past the two-year warranty), and paid a shop to swap it out three years before the recall existed. That rider paid for something that should have been Shimano’s responsibility, and the settlement is designed to make them whole.
How to File Your Reimbursement Claim Before the Deadline
Filing a claim requires visiting ShimanoCranksetSettlement.com and submitting documentation. You will need proof of the original retail purchase of the affected crankset — this could be a receipt from a bike shop, an online order confirmation, or a credit card statement showing the purchase. You will also need supporting documents for the reimbursement itself, such as a repair invoice or receipt showing what you paid for the replacement crankset and installation labor. The tradeoff here is between filing quickly and filing thoroughly. Submitting a bare-minimum claim with weak documentation risks having it reduced or denied, while waiting too long to gather perfect records risks missing the deadline entirely.
A practical middle ground is to start gathering documents now — check your email for old receipts, contact your bike shop to see if they keep records, and pull credit card statements from the relevant time period. Most credit card companies allow you to access statements going back several years through their online portals. If you had the work done at a local bike shop that has since closed, you are not necessarily out of luck, but your claim will be harder to substantiate. Credit card or bank statements showing a payment to the shop around the time of replacement can serve as supporting evidence. The settlement allows reimbursement of “reasonable costs” for parts and installation, so having a clear record of what you actually paid strengthens your position considerably.
The Extended Warranty and Enhanced Inspections — Benefits That Require No Claim
Beyond the reimbursement program, the settlement includes two benefits that apply automatically. First, Shimano has extended the Express Warranty for bonding separation and delamination issues on affected cranksets through July 29, 2027. If you still have an affected crankset on your bike, this means Shimano will cover replacement if the crankset fails due to these specific defects for more than a year beyond the August 2026 reimbursement deadline. No claim form is required for this protection. Second, the settlement mandates an enhanced retailer inspection program.
Shimano must distribute magnifying devices with enhanced lighting to every recall retailer, provide an expert-reviewed inspection manual, and require training for staff performing inspections. This is significant because one of the underlying complaints in the litigation was that the original recall inspection process was inadequate — some riders alleged that cranksets passed inspection only to fail later on the road. A word of caution: the extended warranty covers bonding separation and delamination specifically. If your crankset develops a different type of failure — say, a stripped pedal thread or a bent crank arm from a crash — that falls outside this warranty extension. And while the enhanced inspections are a meaningful improvement, no inspection process catches every defect. If you are riding a crankset from the affected production run, paying attention to any unusual creaking, flex, or visible separation at the bond line remains your best safety measure.
Shimano’s Position and What It Means for Your Claim
Throughout the litigation, Shimano “repeatedly denied any wrongdoing” and characterized the recall as voluntary, stating that “most cranksets work properly.” This is standard language in class action settlements — defendants almost never admit fault as part of a settlement agreement. It does not affect your ability to file a claim or receive reimbursement.
What it does mean, practically, is that Shimano agreed to these settlement terms as a business decision rather than as an admission that every affected crankset was dangerous. For a rider filing a claim, this is largely irrelevant. The settlement terms are binding regardless of Shimano’s public position, and the Settlement Administrator will evaluate claims based on the documented criteria, not on whether Shimano believes the cranksets were truly defective.
What Happens After the August 4, 2026 Deadline
Once the reimbursement claim deadline passes, the Settlement Administrator will process all submitted claims, verify documentation, and distribute payments. The timeline for actually receiving reimbursement checks is not specified in the public settlement documents, but class action payouts typically take several months after the claims deadline closes. Claimants should expect some patience will be required.
Looking ahead, the extended warranty remains in effect through July 29, 2027, giving affected crankset owners roughly another year of coverage beyond the claims deadline. For the broader cycling industry, this settlement — covering 760,000 recalled cranksets — sets a precedent for how bonded carbon component failures may be handled in future litigation. Riders who own any bonded crankset components, not just Shimano’s, would be wise to keep purchase receipts and document any warranty claims carefully.
Frequently Asked Questions
Do I need to file a claim to get the extended warranty on my Shimano crankset?
No. The extended warranty through July 29, 2027 for bonding separation and delamination issues is automatic for all affected cranksets. No claim form is required.
I replaced my crankset in October 2023, after the recall was announced. Can I get reimbursed?
No. If the replacement occurred on or after September 21, 2023, you are not eligible for reimbursement because free replacements were available through the recall at that point.
My bike came with an Ultegra FC-R8000 crankset but I bought it used. Am I eligible?
You may be eligible, but you will need documentation of the original retail purchase and proof of what you paid for the replacement. Check ShimanoCranksetSettlement.com for accepted documentation types if you lack the original receipt.
Are 12-speed Shimano cranksets covered by this settlement?
No. The settlement covers specific 11-speed Dura-Ace models (FC-9000, FC-R9100, FC-R9100-P) and Ultegra models (FC-6800, FC-R8000) manufactured before July 2019. Current 12-speed components are not included.
I replaced my Dura-Ace crankset within the original three-year warranty period but Shimano refused the warranty claim. Can I file for reimbursement?
The settlement states that you are not eligible if the Express Warranty had not yet expired at the time of replacement. If Shimano wrongfully denied a valid warranty claim, that may be a separate issue worth raising with the Settlement Administrator directly through ShimanoCranksetSettlement.com.
How much money will I receive for my reimbursement claim?
The settlement covers “reasonable costs” for parts and installation. The exact amount depends on what you actually paid and what the Settlement Administrator determines to be reasonable. There is no fixed dollar amount per claim.
