Ridley recalls 4ZA carbon stems

Published May 22, 2012

WASHINGTON, D.C. (BRAIN)-Ridley Bicycle is recalling about 105 carbon fiber threadless stems because they can crack or break. So far the company has received one report of a stem breaking in use, resulting in minor injuries, according to the U.S. Consumer Product Safety Commission.

The 4ZA threadless stems were manufactured in Taiwan and sold as aftermarket products. The affected stems are intended for use with 31.8-millimeter handlebars, are black and have the words "4ZA Cycling Performance" painted on the carbon extension between the steerer clamp and handlebar clamp. The recalled stems range in extension lengths from 90 to 130 millimeters.

The stems were distributed by Sinclair Imports and Quality Bicycle Products and sold from January 2005 through April 2010 for about $59 retail.

Consumers should immediately stop using bicycles with these stems and contact the retailer where the stems were purchased to get a free replacement stem. Other bicycle shops can handle the replacement process by contacting the manufacturer's current distributor, QBP.

For additional information, contact QBP toll-free at (877) 745-7703 between 8 a.m. and 6 p.m. CT Monday through Friday or visit www.ridley-bikes.com.
