About 105 4ZA threadless carbon bicycle handlebar stems are being recalled because they can crack or break during use. There has been one report of a stem breaking, which resulted in minor injuries to the rider. These black stems were sold as individual aftermarket components between January 2005 and April 2010. Consumers should stop using bicycles equipped with these stems and contact their retailer for a free replacement.
The carbon extension of the handlebar stem can fail and break while riding, causing the handlebars to detach or lose stability. This can cause the rider to lose control of the bicycle and fall, potentially leading to serious injury.
Consumers should immediately stop using their bicycles and contact the bicycle retailers where the stems were purchased to obtain a free replacement stem. Other bicycle shops can handle the replacement process by contacting the manufacturer's current distributor, Quality Bicycle Products, Inc.

If you or a family member were harmed by this recalled product, you may have legal rights. Consider consulting a consumer protection attorney to understand your options for compensation.
