It looks like DT Swiss identified a problem with several of their carbon 35mm & 45mm deep endurance road, cyclocross & light endurance hybrid ebike wheels. And it is a serious enough issue – resulting in potential carbon rim delamination and unexpected wheel failure – that they are telling all riders with ERC, CRC & HEC carbon wheels to immediately check their DT Swiss ID before riding, and if affected, not to ride them until DT confirms how to proceed – likely with in person inspection or even wheel replacement.
Which DT Swiss wheels affected by this Stop Riding notice?
The issue has the potential to impact a lot of road, all-road & e-road riders since DT Swiss has been selling these popular wheels both on their own and as OEM equipment that may have already come with a bike when you bought it. The good news if you are a DT ERC, CRC, or HEC carbon wheel owner, this only seems to affect wheels manufactured from September 2024 on. And DT has a simple tool on their voluntary recall webpage that makes it easy to check your product serial number.
Affected wheels will have a DT Swiss ID number greater than 2,750,000. You can find that UD number on a sticker between the spokes, on the rim tape, or even under the tape directly on the rim bed. I double-checked mine even though I’ve been riding them without issue since 2021, and confirmed that they are not affected.
Other carbon wheelset ranges like GRC & ARC are not affected, even though your wheels may have a higher DT Swiss ID. I double-checked my GRC wheels with a higher number, and the DT Swiss recall website confirmed that they were fine.
So what’s next after identifying if your wheels are affected? “DT Swiss is working intensively to investigate the root cause. We will provide further updates and guidance as soon as new information becomes available.“
