AFFECTED PRODUCTS
Affected products are bicycle wheels from the following model series delivered from August 1, 2024:
- HADRON² All-Road
- HADRON² All-Road Ultimate
- HADRON² Classic 500
- HADRON² Ultimate 500

These products were sold either as parts of complete bicycles or as individual components through online or specialist retail channels. This product safety recall exclusively affects bicycle wheels where the carbon composite rims (colloquially known as carbon rims) were produced in Vietnam.
PRODUCT IDENTIFICATION
This product safety recall only applies to bicycle wheels with a DT Swiss ID number starting from 2740000. Not all products with a DT Swiss ID number from 2740000 are necessarily affected by this recall. Therefore, checking with the DT Swiss ID number is necessary to determine if the product is subject to this recall.
Please check if your product is affected by the product safety recall using your DT Swiss ID number on the specially set up website:
https://www.dtswiss.com/de/recall
Where to find the DT Swiss ID on your product:
The DT Swiss ID sticker can be found in three different positions on the rim:
- The sticker is located between the spokes.
- The sticker is located on the rim tape.
- The sticker is located in the rim bed.
If the stickers with the DT Swiss ID number are no longer found in the positions shown above, or have become illegible due to wear or age, you can also send the rim serial number located under the rim tape to the email address recall@dtswiss.com. With this number, the DT Swiss team can check via a manual search whether your product is affected by the product safety recall.

WHY IS THE PRODUCT DANGEROUS?
Analysis of reported incidents related to DT Swiss ERC series bicycle wheels has shown that spontaneous delaminations (i.e., separation of the outermost carbon layers) can occur in the rim flange area. The rim bed is not affected by this delamination, but it also sustains damage due to the structural weakening. This form of delamination leads to significant structural weakening, potentially resulting in total rim failure.
The described product defect increases the risk of an accident, which can lead to property damage, severe injuries, or even death.
A potential risk exists for rims of all the above-mentioned model series manufactured in the same production facility in Vietnam from August 1, 2024.
