Shimano Hollowtech II Crankset Settlement – Get Reimbursed by August 4, 2026

What happened

Class period: Cranksets manufactured before July 2019; qualifying replacements made before September 21, 2023.

• In September 2023, Shimano voluntarily recalled certain Hollowtech II cranksets manufactured before July 2019 due to a risk of bonding separation and delamination — which, for a component called "Dura-Ace," is not a great look
• Plaintiffs filed a class action lawsuit alleging the recall was inadequate and that Shimano and major bike retailers (Specialized, Trek, and Giant) misrepresented their products
• A settlement has been reached providing reimbursement for out-of-pocket replacement costs, plus an extended warranty for still-affected cranksets through July 2027

What you can get

Key dates

Who may qualify

• Purchased, received, were given, or owned a Shimano Ultegra FC-6800, FC-R8000, Dura-Ace FC-9000, FC-R9100, or FC-R9100-P crankset manufactured before July 2019
• Your crankset has one of the eligible production codes (KF through RF — full list on the official settlement site and the CPSC recall page)
• You replaced the crankset because it separated, delaminated, or showed signs of delamination or separation
• The replacement happened before September 21, 2023
• The express warranty had already expired at the time of your replacement

How to file

1. 1. Visit the official Shimano crankset settlement website
2. 2. Click "Start Your Claim"
3. 3. Upload documentation of your original purchase and your replacement costs
4. 4. Submit online by August 4, 2026 — or mail your claim form postmarked by August 4, 2026

Proof required

• Proof of original purchase: a receipt, invoice, or photo of the crankset clearly showing the serial number and production code
• Proof of replacement costs: receipt or invoice for your replacement crankset and/or installation labor
• No paperwork? You can submit a signed declaration under penalty of perjury — because apparently some of us don't keep receipts for $500 bike components

Payment timing

Reimbursement will be issued after the court grants final approval of the settlement. Check the settlement homepage for status updates — patience is a virtue, even if your crankset wasn't.
