Trek is recalling 6,800 Madone bicycles because of a faulty bolt on the front brake quick release. The bolt can come loose, causing the cable clamp to come off and make the brake inoperable.
The Waterloo, Wisconsin-based company received 5 reports of loose brake bolts, but no injuries from falls.
The company and US Consumer Protect Safety Commission are urging owners to return the bikes to their local bike shops for a free replacement of the front brake system.
The Madone recall includes model numbers 5.2, 5.9, 6.2, 6.5, 7.7 or 7.9, and serial numbers beginning with WTU and ending in G or H. All colors are included.
Some custom-made Project One Madones are included in the recall.
The bikes, made in the US, Taiwan and Germany, were sold from July 2012 through December 2013 at bike stores. The bikes cost between $3,400 and $6,300; custom models between $4,000 and $15,000.
