Injuries to at least two cyclists have prompted Specialized to recall three models of road bicycles, including the some popular Tarmac models. Facial injuries are reported to have occurred to riders when the steerer tube in the fork broke, according to a press release from the U.S. Consumer Product Safety Commission. The recall affects recent editions of the Tarmac SL4, Crux and Secteur models. The steerer tube connects a bicycle's fork to the frame head tube. Bicyclists should immediately stop using the bikes and contact an authorized dealer for an inspection and free repair.
