Thank you for using SHIMANO products.
On September 21, 2023, Shimano issued a notice on its website regarding an inspection and replacement program of some bonded 11-speed HOLLOWTECH II road cranksets. We would like to provide the latest information as follows:
For the crankset products set out below, in the event you continue its use when such cranksets show signs of bonding separation or delamination, the crank in rare cases may become damaged resulting in loss of balance, falling or injury. Please follow the instructions below to check whether the crankset you have is affected; and upon confirmation, please visit our Hong Kong Authorized Dealer as soon as possible to arrange for inspection free of charge.
We apologize for any concern or inconvenience this may have caused to our consumers.
