Shimano Recalls Millions of Bike Crankarms Over Breakage Concerns

Shimano has issued a global recall for around 2.8 million 11-speed Ultegra, Dura-Ace, and Dura-Ace powermeter crankarms due to a risk of breakage along the bond line.
Affected cranks have manufacturing codes KF through RF. 105 cranks are not affected.
Riders should stop using affected cranks immediately and take them to a dealer for inspection and potential replacement with 12-speed arms.
The failure rate is estimated to be less than 1%. The recall comes after reported failures since 2018.
The recall could impact Shimano's position in the drivetrain market versus SRAM, and potentially cause delays for new bike orders.
