File Your Claim →What Happened?
Shimano, the world's largest manufacturer of bicycle components, was sued after it was alleged that its Hollowtech II cranksets manufactured before 2019 contained a design defect that could cause the crank arm to detach from the bottom bracket — creating a serious fall hazard for cyclists. Riders who experienced this failure while cycling could be thrown from their bikes at speed, risking serious injury.
Shimano issued a safety notice but was criticized for not doing enough to warn cyclists or address the defect proactively. The settlement covers anyone who purchased an affected Hollowtech II crankset manufactured before 2019.
How Much Will I Actually Get?
Settlement compensation includes either a cash payment or a replacement crankset depending on your preference and circumstances. Proof of purchase is recommended to maximize your claim. Check the official settlement website for the current claim deadline and full list of qualifying crankset models.
