Bike recall: More than 700,000 bicycles affected by faulty Shimano cranksets

Bike manufacturer Shimano has recalled more than 700,000 cranksets after 4,500 incidents, including some injuries.

The 11-Speed Bonded Hollowtech II Road cranksets can separate and break, according to an announcement from the Consumer Product Safety Commission (CPSC.) The recall involves 680,000 cranksets in the United States, plus 80,000 in Canada. 

The affected cranksets are on Shimano bikes and on bikes manufactured by other companies, including Trek. The recall involves those manufactured before July 2019 models with an ‘Ultegra’ or Dura Ace’ logo. 

A crankset connects the chain to the pedals. 

Shimano has received 4,519 complaints of cranksets separating. Six of those cases caused injuries, including bone fractures, cuts and dislocated joints. Affected consumers should contact Shimano or a Shimano dealer for a free inspection. The company noted that only cranksets that show early signs of separation will be repaired at no charge.

The affected Shimano bikes were sold nationwide from January 2012 through August 2023. They cost $270 to $1,500. Shimano North America Bicycle Inc. is based in Irvine, California.
