Bike parts manufacturer Shimano recalling cranksets amid reports of faults and injuries

Cyclists who ride bikes with certain models of Shimano cranksets are being warned by the bicycle parts manufacturer to have them checked, or risk a fall or crash.

Shimano has issued a recall for its speed-bonded Hollowtech II road cranksets, suitable for certain Ultegra and Dura-Ace models, the Australian Competition and Consumer Commission said.

The bonded crank parts can separate and break, leading to potential falls and crashes.

Australian cyclists are being warned amid a global recall.

"There is a risk of a fall or crash if the crank arm separates," the ACCC said.

"At the time of publishing, Shimano has received 4,519 incidents of cranksets separating, and six reported injuries, including bone fractures, joint displacement and lacerations."

The affected models are the Ultegra FC-6800 and FC-R8000, and the Dura-Ace FC-9000, FC-R9100 and FC-R9100-P.

The cranksets were manufactured between June 1, 2012 and June 30, 2019. A two-letter manufacturing code is stamped on the inside of the crank arm.

Cyclists should not use a bike with Shimano Ultegra or Dura-Ace cranksets until they check if theirs is an affected model.

Anyone with an affected model should contact a Shimano dealer to arrange for the cranksets to be inspected. Any cranksets that fail the inspection process will be replaced free of charge.
