Shimano crankset recall. What does it mean and what is the process?

A bike mechanic is inspecting a crank.

Shimano is currently issuing a voluntary recall of some bonded Ultegra and Dura-Ace 11-speed Hollowtech road cranksets produced between 2012 to 2019 for a possible bonding separation issue, posing a crash hazard to consumers.

What does this mean?

To remedy this situation, Shimano will have applicable cranks inspected by Shimano authorized retailers and Shimano will replace any cranks that fail the inspection process. There is no need for further action for cranks that pass the inspection process.

What is the process?

  1. Not all Ultegra and Dura-Ace cranks need to be inspected, only cranks produced between 2012 to 2019. You can identify if your crank is applicable at this Canadian government web page or see instructions below.

  2. If your crank is applicable, you can bring it to our shop for inspection free of charge. We will take the crank off your bike, clean the crank arm thoroughly and conduct an inspection according to the Shimano guidelines.

  3. Consumers whose cranksets show signs of bonding separation or delamination during the inspection will be provided a free replacement crankset and installation.
