BMC Switzerland calls a hard stop on the Kaius 01, recalling all models and framesets over concerns with the fork’s steerer tube. The Swiss brand cites several cases where specific steerer tubes have separated under “heavy-duty riding conditions.” While the issue seems limited, BMC is erring on the side of caution and replacing affected forks with a more robust version.

What BMC Kaius 01 Owners Need to Know

BMC is asking all Kaius 01 owners to stop riding immediately and take their bikes to a BMC retailer for inspection. If a fork replacement is needed, the retailer will install a new one at no cost to the rider.

How dealers will determine if a fork needs replacing is still unclear. However, what is clear is that BMC is getting ahead of this issue before an official CPSC (Consumer Product Safety Commission) announcement—not the first time the brand has had to issue a recall related to steerer tubes, like the stop ride notice for the Teammachine SLR01 DISC bicycles and framesets.

Which Bikes Are Affected?

If you own any of the following 2023, 2024, or even 2026 Kaius 01 models, your bike is subject to the recall:

• 2023 BMC Kaius 01 ONE, TWO, THREE
• 2024 BMC Kaius 01 LTD, ONE, TWO, THREE
• 2026 BMC Kaius 01 THREE, FRS

What to Do Next

BMC is working to replace affected forks as quickly as possible and apologizes for the inconvenience. If you have any questions, you can contact BMC through their website or by phone:
