Shimano to recall thousands of Ultegra and Dura-Ace chainsets due to crash hazards posed to cyclists

Shimano issued the voluntary recall as part of their ‘inspection and replacement campaign’ following 4,519 reported incidents of chainset (‘crankset’ in the US) failures in the US and Canada alone, which led to six injuries including joint displacement, lacerations, and bone fractures. Global figures for injuries are currently unknown.

The recall is set to have a huge impact on cyclists, bike shops, as well as Shimano itself. The affected models were manufactured prior to 2019, and comprise of the following:

• Ultegra FC-6800
• Ultegra FC-R8000
• Dura-Ace FC-9000
• Dura-Ace FC-R9100
• Dura-Ace FC-R9100P (power meter)

The United States Consumer Product Safety Commission (CPSC) reported that the bonded construction of the affected products could separate and break, meaning that riders are at risk of crashing.

Consumers are advised to stop using affected products and contact a Shimano dealer where a free replacement will be issued if signs of separation of the components are found.

Leigh Day consumer lawyer Tom Jervis said:

“There have been an alarming number of reported incidents of Shimano chainset failures. I hope that Shimano takes swift action in recalling the faulty products to prevent further injury and does better in the future to create robust, quality products that do not pose risks to consumers.”
