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. Hospital admission

    Made Nov 17, 2022, sent to the company Nov 21, 2022, published by CPSC Dec 6, 2022

    The product, in the report: KCNC REYTON MTB ±25 Degree Stem 31.8mm / 35mm x 90mm, Anodized Black, ST37-25-90-35, SK2112 stem (This is a mountain bike stem which holds the bike’s handlebars and attaches to the bike’s steering tube)

    I was riding my fat tire bicycle on Wednesday, November 16, 2022 at Carver Park Reserve in Victoria, Minnesota. I was .15 miles into my ride going downhill into a curve when the stem on my bike broke causing the handlebars to come off the steering tube resulting in a complete loss of control of steering and a resultant crash. I landed very hard hitting my head, getting the wind knocked out of me, overextended both wrists, some bruising, sore chest. I was very, very fortunate to not be going faster and did not experience more severe injuries or death. As can be seen in the photos, the metal bracket (advertised as Aluminum AL750) and titanium screws both failed structurally causing the accident. Based on my riding data, I’m guessing that I used this stem for approximately 45 to 50 rides totalling around 500 miles. I don’t recall any bad falls that would have stressed the stem. This has apparently happened to at least one other person who experienced an accident by a different version of this KCNC stem who commented in his Amazon review [REDACTED] and [REDACTED]. I never saw his review until I experienced my accident. Please issue an immediate order to stop all sales of bike stems from this manufacturer to prevent the possibility of severe or fatal injury. Additionally, please use Amazon’s sales database to notify other purchasers of KCNC stems to immediately discontinue use. I wish I had received notice of the danger of this stem. Purchase info: I purchased KCNC REYTON MTB ±25 Degree Stem 31.8mm / 35mm x 90mm, Anodized Black, ST37-25-90-35, SK2112 stem from Amazon on October 19, 2010. Amazon order number: [REDACTED] Item cost $95.00
