22th-Nov, 2023

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.

Free Inspection and Replacement Instructions

1. Check the crankset model number

The following 5 models produced on or before 30 June 2019 are affected:

ULTEGRA Series

DURA-ACE Series

2. Identify the production code of the crankset

The following two-letter production code is stamped  on the inside of the crankarm near the bottom of the arm.

Please refer to the sample image of the inside of the crankarm below (yellow box: the model number, blue box: the production code)

3. Starting date of the Free Inspection Program

The Free Inspection Program will start on 22th-Nov, 2023.

Consumers with the affected crankset products should swiftly contact the Hong Kong Authorized Dealer to schedule a free crankset inspection. Please visit the website of the Hong Kong Authorized Dealer at

Please call the Hong Kong Authorized Dealer at 26702668 / 26686293 if there are any queries.

We will replace any crankset if we consider it necessary after our inspection. Otherwise, you may continue using your existing crankset if we consider replacement is not necessary.

To ensure consumers’ peace of mind, we recommend that your crankset be inspected a second time about one year after the initial inspection if we determine that such crankset does not need to be replaced at the initial inspection. However, if you observe any abnormalities concerning your crankset throughout this time, please visit our Hong Kong Authorized Dealer as soon as possible to arrange for inspection. The initial and second inspections will be free of charge.

In addition, we recommend you perform regular crankset checks on your own after the second inspection. Please refer to the following link for instructions on how to check the crankset on your own.

Depending on the specifications of your crankset, we may need some time to arrange for replacement.
