To file a claim in the Shimano Defective Crankset Settlement, visit the official settlement website at www.shimanocranksetsettlement.com, complete the claim form, and submit documentation proving you replaced a covered crankset before September 21, 2023. You can also mail your claim to the Settlement Administrator at P.O. Box 4150, Portland, OR 97208-4150. The deadline to submit a documented reimbursement claim is August 4, 2026, so you still have time — but gathering receipts and records now will make the process far smoother. This settlement stems from a class action lawsuit filed against Shimano North America Bicycle, Inc., Shimano North America Holding, Inc., and major bicycle manufacturers Specialized Bicycle Components, Inc., Trek Bicycle Corporation, and Giant Bicycle, Inc.
Judge James V. Selna in California Central District Court granted final approval on February 4, 2026, after Shimano voluntarily recalled Hollowtech II cranksets manufactured before July 2019 due to a crash hazard from bonding separation and delamination. For example, if you bought a road bike equipped with a Shimano Ultegra FC-R8000 crankset in 2018 and paid out of pocket to replace it after noticing delamination, you may be entitled to reimbursement for those costs. This article walks through exactly which crankset models qualify, what documentation you need, how the reimbursement process works, and key limitations that could disqualify your claim. We also cover the automatic extended warranty benefit that requires no paperwork at all.

What Do You Need To File A Claim In The Shimano Crankset Settlement?
Filing a claim requires two things: proof that you owned a covered crankset, and proof that you paid to replace it before the recall date. Specifically, the settlement administrator is looking for original purchase receipts showing the crankset model or bicycle model, along with credit card statements that include merchant details confirming the transaction. If you bought a Trek Émonda equipped with a Dura-Ace FC-R9100 crankset in 2017 and then paid a local bike shop $400 to swap it out in early 2023, you would need the original bike purchase receipt, the shop invoice for the replacement work, and ideally a credit card statement showing the charge. The claim form itself is available at www.shimanocranksetsettlement.com and can be submitted online or by mail.
If you prefer to mail your claim, send it to Settlement Administrator, P.O. Box 4150, Portland, OR 97208-4150. For questions about the process, there is a toll-freetoll-free[contact via the official settlement website]. The settlement covers “reasonable, documented out-of-pocket costs” for the replacement crankset and its installation, so keep that language in mind — undocumented expenses or inflated claims are likely to be denied or reduced.
Which Shimano Crankset Models Are Covered Under This Settlement?
The settlement covers five specific Shimano Hollowtech II crankset models, all of which must have been manufactured before July 2019. The covered models are: Ultegra FC-6800, Ultegra FC-R8000, Dura-Ace FC-9000, Dura-Ace FC-R9100, and Dura-Ace FC-R9100-P (the power meter variant). These cranksets were widely used on mid-range to high-end road bikes sold by Specialized, Trek, Giant, and other manufacturers during that production window.
However, if your crankset is a different Shimano model — even another Hollowtech II variant like the 105 FC-R7000 — it is not covered by this settlement. The defect specifically involved bonding separation and delamination in these five models, which the CPSC flagged as a crash hazard in September 2023. It is also worth noting that cranksets manufactured after July 2019 are excluded, even if they carry the same model number. You can typically identify the manufacture date by checking the two-letter date code stamped on the inside of the crank arm.
Who Qualifies For Reimbursement And Who Does Not
Eligibility hinges on a few specific conditions. You must have purchased, received, or owned a covered crankset — or a bicycle equipped with one — in the United States. The reimbursement component is specifically for class members who replaced a defective crankset before September 21, 2023, which is the date Shimano issued its voluntary recall through the CPSC. If you replaced your crankset after that date, the recall program itself should have covered the replacement, and you are not eligible for reimbursement through this settlement.
There is another exclusion that catches some people off guard. If the Express Warranty on your crankset had not yet expired at the time you replaced it, you are also ineligible for reimbursement — because the warranty should have covered the replacement at no cost. The warranty periods are two years from purchase for the Ultegra models (FC-6800 and FC-R8000) and three years from purchase for the Dura-Ace models (FC-9000, FC-R9100, and FC-R9100-P). So if you bought a bike with an Ultegra FC-R8000 in January 2022 and replaced the crankset in June 2023, the two-year warranty would still have been active, and your claim would be denied.
How The Extended Warranty And Automatic Benefits Work
Not every benefit in this settlement requires filing paperwork. One of the most significant provisions is the extended warranty: Shimano will extend the Express Warranty on all covered cranksets to July 29, 2027, specifically for bonding separation and delamination issues. This extension is automatic and requires no claim form, no documentation, and no action on your part. If you still have a covered crankset on your bike, you are protected through that date. The tradeoff here is straightforward.
If your crankset has not yet failed, the extended warranty is your safety net — you do not need to preemptively replace it. But if it does fail before July 29, 2027, the warranty should cover the replacement at no cost. Compare that to the reimbursement path, which is only available to riders who already paid out of pocket for a replacement before the recall was announced. In other words, the settlement creates two parallel tracks: one for people who already spent money fixing the problem, and one for people whose cranksets might still fail in the future. Additionally, the settlement requires Shimano to overhaul its recall inspection process, including mandated training and equipment for retailers who handle crankset inspections. This is a less visible benefit, but it means that if you bring your bike to a Shimano-authorized dealer for an inspection, the process should be more thorough and standardized than it was before the lawsuit.
Common Issues That Could Delay Or Disqualify Your Claim
The most frequent problem claimants face is insufficient documentation. If you replaced your crankset at a small bike shop that has since closed, or if you did the work yourself and paid cash, proving your out-of-pocket costs becomes significantly harder. The settlement requires receipts and credit card statements with merchant details — vague bank entries or handwritten notes are unlikely to satisfy the administrator. Start gathering your records now rather than waiting until closer to the August 4, 2026 deadline.
Another issue to watch for: the settlement covers “reasonable” costs. If you replaced a $200 Ultegra crankset with a $600 aftermarket upgrade, the reimbursement will likely be limited to what a comparable replacement would have cost, not the full amount you spent. The administrator has discretion to evaluate whether claimed expenses are reasonable, so expect some scrutiny if your replacement costs seem disproportionate to the value of the original part. Claims that include professional installation labor at standard shop rates should generally be fine, but unusually high labor charges could be questioned.
Filing By Mail Versus Filing Online
Most claimants will find the online process at www.shimanocranksetsettlement.com faster and more convenient. The site allows you to upload digital copies of your receipts and documentation, and you will receive confirmation that your submission was received.
Filing by mail to P.O. Box 4150, Portland, OR 97208-4150 is a viable alternative, particularly if your documentation is in paper form and difficult to scan — but mail claims take longer to process and you will not have the same instant confirmation. Whichever method you choose, keep copies of everything you submit.
What Happens After The Claim Deadline
The August 4, 2026 deadline to submit reimbursement claims is firm, and the settlement administrator is unlikely to accept late filings absent extraordinary circumstances. After claims are processed and approved, reimbursement payments will be distributed to eligible class members.
The extended warranty component, however, continues to protect crankset owners through July 29, 2027, regardless of whether they filed a claim. For the cycling industry more broadly, this settlement sets a precedent for how component defects on high-end bikes are handled — manufacturers and the brands that spec their parts are on notice that warranty shortcomings and delayed recalls carry real legal consequences.
Frequently Asked Questions
Do I need to file a claim to get the extended warranty on my Shimano crankset?
No. The extended warranty to July 29, 2027 is automatic for all covered crankset models. You do not need to submit any paperwork.
I replaced my crankset after the September 2023 recall. Can I still file for reimbursement?
No. Reimbursement through this settlement is only available to class members who replaced their crankset before September 21, 2023. Replacements after that date should have been handled through the recall program itself.
My crankset is a Shimano 105. Is it covered?
No. The settlement only covers five specific models: Ultegra FC-6800, Ultegra FC-R8000, Dura-Ace FC-9000, Dura-Ace FC-R9100, and Dura-Ace FC-R9100-P, all manufactured before July 2019.
What if I lost my original purchase receipt?
Credit card statements showing the merchant and transaction amount can serve as supporting documentation. However, claims without any purchase documentation are unlikely to be approved. Contact the settlement administratorsettlement administrator[contact via the official settlement website] for guidance on your specific situation.
Can I file a claim if I bought my bike used?
The settlement covers anyone who “purchased, received, or owned” a covered crankset or a bicycle equipped with one in the United States. Secondhand buyers are included, but you will still need documentation of the replacement costs you incurred.
What is the deadline to file a claim?
