Sign in to monitor this recall

Summary

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.

Risk

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.

What You Should Do

  1. Check your bicycle for a black handlebar stem with the words '4ZA Cycling Performance' painted on the carbon extension between the handlebar and the steerer tube.
  2. Measure the extension length of the stem; affected units range from 90mm to 130mm (approximately 3.5 to 5 inches) in length.
  3. Immediately stop using any bicycle equipped with a recalled 4ZA 31.8 threadless stem.
  4. Contact the specialty bicycle retailer where you purchased the stem to receive a free replacement stem.
  5. If your original retailer is unavailable, take your bicycle to any local bike shop; they can facilitate the replacement by contacting the distributor, Quality Bicycle Products, Inc. (QBP), at (877) 745-7703 between 8 a.m. and 6 p.m. CT Monday through Friday.
