product safety recall

Update on the recall process (August 14, 2025)

For about two weeks now, we have been sending many hundreds of return boxes each day to affected customers. We kindly ask for your understanding that it took some time for processes to stabilize and that, in the early stages, we could not always use the ideal packaging. The procedure is now running more smoothly, and every day we receive many hundreds of returns at our dedicated service centers for this recall. We have also expanded our testing capacities and increased our service teams to speed up processing.

Our customer service team is also handling a very large number of enquiries daily. Before contacting us, please carefully review our recall website and FAQs – many questions are already answered there, enabling us to focus more effectively on individual cases.

From this week onward, we have begun returning many hundreds of checked and approved wheelsets to affected customers.

Product Safety Recall (July 29, 2025)

Dear DT Swiss customers and business partners,

Following the Stop-Use Notice issued on July 12, 2025, and after comprehensive analysis and the development of a structured resolution process, we are now announcing an official product recall. We would like to inform you that DT Swiss is recalling affected wheel models of the ERC, CRC, and HEC series with rim heights of 35 and 45 mm and models of the ARC series with rim heights of 50, 55, and 65 mm. While the initial Stop-Use Notice applied to selected ERC, CRC, and HEC wheels, the recall includes ARC models manufactured at the same facility. Although no product defects have been reported for the ARC series, in-depth quality checks have revealed manufacturing concerns similar to those previously identified in the ERC/CRC/HEC models.

Please note that ARC wheel models in rim heights of 38, 62, 80, and 85 mm are NOT included in the recall. Furthermore, all rims manufactured in DT Swiss`s own facility in Poland are NOT affected by this recall.

Please also inform your family, friends, and acquaintances about this product safety recall!

Swiss Side - product safety recall

This product safety recall also includes products from SwissSide. HADRON models with rim heights of 450, 500, 550, and 650 are included.

Although no product defects have been reported for those wheels, in-depth quality checks have revealed manufacturing concerns similar to those previously identified by DT Swiss.

Please note that HADRON wheel models: 380, 625, 680 and 850 are NOT included in this recall. Furthermore, all rims manufactured in DT Swiss`s own facility in Poland are NOT affected by this recall.

The subsequent information and process steps, including product identification (DT Swiss ID) and remedial measures, apply to both affected DT Swiss and Swiss Side products. Your processing partner for this product safety recall is DT Swiss.

These products were sold either as parts of a complete bicycle or as individual components via online retailers or specialist shops. This product safety recall only affects bicycle wheels with carbon fiber composite rims (commonly known as carbon rims) that were manufactured in Vietnam. Only bicycle wheels with a DT Swiss ID number of 2740000 or higher are potentially affected by this product safety recall! Not all products with a DT Swiss ID number of 2740000 or higher are necessarily affected by this product safety recall. It is therefore necessary to check the DT Swiss ID number to determine whether your product is subject to the product safety recall (see «Check Your Product» below).

check whether your product is affected

1. If you have one of the wheels in the above-mentioned series, please immediately discontinue the use of the products. 
2. If your product has a DT Swiss ID higher than 2740000, please check to see if your product is affected in the «CHECK HERE» field provided below.
3. If you purchase a complete bicycle, both the front and rear wheels may be affected (wheelset).
4. If your product is identified, you will be shown a form directly on this webpage where you can enter in your contact information and register your wheel for the product safety recall. 
5. If you want to identify if your affected product has been checked and approved, scan the QR code of your DT Swiss ID with your phone or in the «SCAN THE QR CODE» field provided below.

Further procedure and REMEDIAL MEASURES FOR CUSTOMERS 

1. Registration: Once you have registered your affected wheel or wheelset, we will contact you within 24 hours with details on how to proceed.  
2. Shipping Boxes: You will be provided with a link where you can order shipping boxes. For each registration, you will receive two empty cardboard boxes, inlays, and assembly instructions. If you have two affected wheel sets, you must register twice. We will also send you shipping information depending on your country.  
3. Prepare & Ship Wheels: If possible, we ask you to send in wheels without tires, brake discs, and cassettes. If you are unable to remove these components, you can either seek assistance from your local dealer or send in the wheels with the components still attached. Expenses (e.g. disassembly costs charged by dealers) will be reimbursed. Customers who send in wheels with the specified components will of course not be disadvantaged in any way.  
4. Processing Time: As soon as we receive the wheels, we will process them as quickly as possible. Depending on the country, the processing time is estimated at a maximum of 20 working days during the first six weeks, with the target for all service centers being less than 10 working days.  
5. Quality Test: We will check all wheels returned to us by conducting a quality test in order to identify the defective products. With this quality test, we define internal company requirements that exceed the specifications of the relevant industry standard (ISO 4210 series). Only products that fulfil these strict internal company requirements are declared as safe, labelled accordingly. 
6. Return Shipment or Replacement: Wheelsets that pass the quality test will be returned to the registered address. The wheels will be returned in the same condition as they were delivered to us. If a wheel is found to be defective, we will immediately contact you with proposal for a free replacement wheel. Returned and replaced wheels will have a round Quality check sticker on the rim to confirm the product was tested and passed.
7. Check Quality Test Status: All affected wheel types that have been to a service center and passed the quality test can still be checked later by scanning the QR code of your DT Swiss ID with your phone . All checked and passed wheels will be identified by the system as checked and released; the check can therefore be traced at any time.
