Norco Bicycles, a division of LTP Sports Group Inc., of Port Coquitlam, British Columbia, is recalling about 90 2011 model Havoc bicycles because their frame can crack at the joint where the top tube meets the down tube.


 A cracked tube can separate and cause the rider to lose control, posing a risk of injury or death. The firm has received three reports of cracked frames. No injuries have been reported.


The recall involves 2011 Havoc 24-inch and 26-inch bicycles. The 24-inch bicycles were sold in semi-matte grey and the 26-inch in semi-matte red. On some of the bicycles, “Norco” is printed on the firm's crest that is affixed to the head tube. Bicycle frames included in this recall have serial numbers that begin with K10DQ, K10FQ, K10IQ, K10KQ P10K, P10F or P11B. The serial number is stamped on the underside of the bottom bracket, below the word “Havoc.”


The bikes were made in China and sold at authorized Norco dealers nationwide from November 2010 to September 2011 for about $600.


The U.S. Consumer Product Safety Commission said consumers should immediately stop using the recalled bike and return them to an authorized Norco dealer for a replacement.
