Welcome to the Information Website for the Shimano Crankset Litigation.

If you purchased, received, were given and/or owned a Designated Crankset or a bicycle equipped with a Designated Crankset in the United States, you may be eligible to receive benefits from a class action settlement.

Designated Crankset means any of the following Shimano cranksets manufactured before July 2019: Ultegra FC-6800, Ultegra FC-R8000, Dura-Ace FC-9000, Dura-Ace FC-R9100 and Dura-Ace FC-R9100-P, with any of the following production codes: KF,KG, KH, KI, KJ, KK, KL, LA, LB, LC, LD,LE, LF, LG, LH, LI, LJ, LK, LL, MA, MB,MC, MD, ME, MF, MG, MH, MI, MJ, MK,ML, NA, NB, NC, ND, NE, NF, NG, NH, NI, NJ, NK, NL, OA, OB, OC, OD, OE, OF,OG, OH, OI, OJ, OK, OL, PA, PB, PC, PD,PE, PF, PG, PH, PI, PJ, PK, PL, QA, QB,QC, QD, QE, QF, QG, QH, QI, QJ, QK, QL,RA, RB, RC, RD, RE, and RF.

Photographs of the Designated Cranksets and where to locate the production codes are available at https://www.cpsc.gov/Recalls/2023/Shimano-Recalls-Cranksets-for-Bicycles-Due-to-Crash-Hazard.

A settlement has been reached in a class action lawsuit against Shimano North America Bicycle, Inc. and Shimano North America Holding, Inc. (together, “Shimano”), and Specialized Bicycle Components, Inc., Trek Bicycle Corporation, and Giant Bicycle, Inc. (collectively, “Defendants”). In September 2023, Shimano voluntarily recalled Shimano Hollowtech II cranksets in the United States that had been manufactured before July 2019 (the “Voluntary Recall”). Plaintiffs alleged breaches of warranties and sought relief in connection with the advertising and marketing of Defendants’ products and the alleged inadequacy of the voluntary recall. There are no allegations that Plaintiffs have suffered any physical injuries from the cranksets involved.

You are a Settlement Class Member entitled to receive benefits under the Settlement if the following Settlement Class definition applies to you: all Persons who purchased, received, were given, and/or owned a Designated Crankset in the United States, other than solely for resale purposes. This includes, without limitation, Persons who purchased, received, were given, or owned a bicycle equipped with a Designated Crankset.

This Settlement may affect your rights. Please read it carefully.

Extended Warranty: For Designated Cranksets otherwise covered by Shimano's Express Warranty, Shimano will extend the duration of the Express Warranty until July 29, 2027. This extension applies only to the Express Warranty's coverage of bonding separation and delamination. Delamination refers to the early stages of separation at the interface (the part where the two parts are bonded together) between the crank set body and cover. Evidence of delamination may include signs of corrosion and breaking.

You do not need to submit a Claim Form to receive extended Express Warranty coverage, it will be extended automatically.

Enhanced Inspections: Shimano will (1) distribute a magnifying device with enhanced lighting to every Recall Retailer free of charge; (2) distribute an Approved Enhanced Manual to Recall Retailers; (3) make Shimano employees available to Recall Retailers during normal business hours in California to advise about how to perform inspections; (4) require Recall Retailers to affirm that they have reviewed and will utilize all materials provided by Shimano related to the Inspections; (5) instruct Recall Retailers to make certain information available to Settlement Class Members whose Designated Crankset passes an inspection, which information describes what to watch, listen, and feel for as indicators of conditions that could lead to bonding separation, delamination, or breakage; and (6) provide public outreach to maximize Settlement Class Members' participation in the Voluntary Recall.

Reimbursement of Costs: If you replaced your Designed Crankset because it separated, delaminated, or exhibited evidence of delamination or separation, you may submit a Claim Form with supporting documentation to receive reimbursement of reasonable out-of-pocket costs for purchasing a replacement crankset and installing it on your bicycle.

Reimbursement is not available if (a) the Designated Crankset was replaced on or after September 21, 2023, or (b) at the time of replacement, the Express Warranty was not expired as to that Designated Crankset. For Ultegra FC-6800 and FC-R8000 Designated Cranksets, the Express Warranty expired two years after the date of original retail purchase. For Dura-Ace FC-9000, R9100, and FC-R9100-P Designated Cranksets, the Express Warranty expired three years after the date of original retail purchase.

You must submit your documented reimbursement claim to the Settlement Administrator by August 4, 2026.
