The reports, as CPSC published them

Reports people made to the U.S. Consumer Product Safety Commission. CPSC publishes each one after sending it to the company named, and doesn’t guarantee they’re accurate. A report isn’t a recall.

Each report is the words of the person who made it, as CPSC published them. The company’s comments, where CPSC published any, are set apart as the company’s own.

  1. First aid

    Made Nov 7, 2025, sent to the company Nov 19, 2025, published by CPSC Dec 4, 2025

    The product, in the report: It is a KMC X11SL bike chain.

    My son was riding his bike on 11/2/2025 when the chain suddenly snapped on his bike. This caused him to flip over the bike and suffer cuts, bruises, and we believe a concussion when he landed. The chain was a KMC X11SL chain manufactured by KMC. I’ve never submitted a report before on any product, however this sudden chain snapping could have killed him. The sudden chain braking caused the handlebars to snap left and throw him over the bars. Strangers helped pick him up and take care of him until we were able to get him. He is 16 years old. I have reached out to the company on three occasions via email and [REDACTED] but have not heard back. The company has a history of fake products being sold as theirs (no fault of the company). However this appears to be a real, legitimate chain based on close up photos comparing real/fake chains. I still have the broken chain and all parts. The rest of the bike is in excellent condition, still on its first set of tires. A chain should never fail the way this one did. It did not break at a “pin” which I have seen happen, this one the actual link snapped in half.

    UPDATED ON 11/24/2025: [I did find a production code on the broken chain I reported. The chain has a 1 and a 1E stamped on it which the company can use to determine when and where it was made. I have asked the company for this information but they have not responded yet with any additional information.]
