Consumers should stop using recalled products immediately unless otherwise instructed. It is illegal to resell or attempt to resell a recalled consumer product.
Name of Product: 10 Speed SRAM Bicycle Chains with PowerLock connector links
Units: About 24,000
Manufacturer: SRAM LLC, of Chicago, Ill.
Hazard: The recalled PowerLock connector links, used on bicycle chains, are brittle and can crack, allowing the chain to separate from the bicycle and posing a fall hazard to the rider.
Incidents/Injuries: One incident has been reported in the United States and three outside. No injuries have been reported.
Description: The recall involves SRAM PowerLock connector links, which are sold individually, on 10-speed bicycle chains and as original equipment on some bicycles. The recalled PowerLock connector links are identified by a date code of M or N, which is located on the side of the PowerLock connector link. 10-speed SRAM chains that were equipped with recalled PowerLock connector links include the following chain model numbers: PC-1030, PC-1050, PC-1070, PC-1090 and PC-1090R. The recalled chains were also installed on some Guru, Surly, Salsa, BMC, Serotta, Seven, and Ridley brand complete bicycles. The individual PowerLock connectors and bike chains with these connectors were sold from January 2009 through August 2009; bicycles with affected chains were sold from April 2009 through August 2009.
Sold at: Specialty bicycle retailer stores nationwide from January 2009 through August 2009. PowerLock connector links were sold separately for about $5 or as part of 10-speed chains for between $35 and $85.
Manufactured in: Portugal
Remedy: Consumers should immediately stop using the recalled PowerLock connectors, chains and bicycles with these connectors and contact their SRAM retailer for a free replacement PowerLock connector link.
Consumer Contact: For additional information, contact SRAM at (800) 346-2928 between 9 a.m. and 5 p.m. Monday through Friday CT or visit the firm's Web site at www.sram.com
Check your SRAM chains, if you think you still have an older one on your bike. A chain that breaks unexpectedly is not only a fall hazard, it can cause loss of control that can get a rider killed in traffic.
I don't remember shimaNO having any chains recalled, but they did have the CSPC recall cranksets, handlebar stems and handlebars (Pro Vibe, imported by shimaNO this fall).
