Yakima is recalling about 7,000 bicycle racks used on vehicles with rear-door spare tires.

Documents posted on the National Highway Traffic Safety Administration website Friday say that mounting bolts can break and the bikes can fall from the vehicles and cause a hazard.

The recall affects SpareTime two-bike racks made from Nov. 1, 2011 through Oct. 30, 2012. The manufacture date is printed on a white label on the rack's mounting plate. Yakima says that only bolts without markings on the heads are affected by the recall.

Yakima found the problem after getting complaints from two customers. It's asking dealers for a list of buyers and says it will send new mounting bolts free of charge.

The company said Friday that the problem hasn't caused any injuries.

Customers can call Yakima at (888) 925-4621.
