Shimano recalls 11-speed cranks

Shimano has recalled cranksets on some Dura-Ace and Ultegra models due to a fault that can cause the crank arm to separate from the main crank.

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

The cranksets are of the Hollowtech design, in which components of the crank are bonded together.

Shimano says that the bonded crank parts can separate and break. "There is a risk of a fall or crash if the crank arm separates,” the company says.

"At the time of publishing, Shimano has received reports of 4519 incidents of cranksets separating, and six reported injuries, including bone fractures, joint displacement and lacerations.”

Consumers should not use a bike with a Shimano Ultegra or Dura-Ace crankset until they check whether theirs is an affected model. Instructions on how to check are on the Shimano website.

The following model series are subject to the recall:

  • Ultegra: FC-6800, FC-R8000
  • Dura-Ace: FC-9000, FC-R9100 and FC-R9100-P

The two-letter codes are: KF to KL, LA to LL, MA to ML, NA to NL, OA to OL, PA to PL, QA to QL, and RA to RF.

If you have an affected model, contact your nearest authorised Shimano dealer to arrange for the cranksets to be inspected. Any cranksets that fail the inspection process will be replaced free of charge.

For more information, consumers can contact Shimano on 1800 269 958 from 8am to 5pm AEST Monday to Friday, or online at https://bike.shimano.com/en‐AU/information/contact‐shimano.html
