Bicycle Crank Shafts Recalled Following Injury Reports

<"">Full Speed Ahead Crank Sets, which are used by numerous bicycle manufacturers, have been recalled due to crash hazard, the U.S. Consumer Product Safety Commission (CPSC) just announced. The CPSC is advising consumers to stop using the recalled Full Speed Ahead Crank Sets immediately and notes that it is illegal to resell or to attempt to resell a recalled consumer product.

About 9,300 Full Speed Ahead BB30 Gossamer Crank Sets, which were manufactured by TH Industries, of Taiwan; imported by Full Speed Ahead, of Woodinville, Washington; and installed on numerous makers of bicycles, are involved in this recall.

If the fixing bolt is over-tightened on the non-drive crank arm, the bolt shoulder can crack or break. If this occurs, the non-drive arm can fall off the bicycle causing the rider to crash and suffer injuries. To date, Full Speed Ahead has received 11 reports of incidents, including two cases in which injuries have been reported.

A crank set is the component of the bicycle that the chain and pedals attach to for pedaling. The recalled models are either painted black with “Gossamer” printed in white on the arm or white with “Gossamer” printed in black on the arm. There are two drive gears (referred to as “double”) on the crank set. The recalled crank arms were assembled as original equipment on the following bicycle models:

Gossamer BB30 non-drive crank arms that are included in the recall have serial numbers beginning with 10B, 10C, and 10D. Serial numbers are located on the backside of the crank arm by pedal threads. MegaExo model Gossamer cranksets and Gossamer BB30 cranksets with three drive gears (referred to as “triple” cranksets) are not involved in this recall.

The recalled Crank Shafts were assembled as standard original equipment on the bicycles listed and were sold by independent bicycle retailers nationwide from February 2010 through October 2010. The CPSC is advising consumers to immediately stop using bicycles that have the recalled crank arm sets and return the bicycle to the dealer. The dealer will install the new non-drive crank arm free of charge.
