Trek Mountain BIke Recall
 

Trek is recalling nearly one million mountain bikes. The corrective action is to replace the skewer on these bikes. The failure of three bikes has resulted in serious injuries, so this should be taken seriously. If you've got a Trek MTB with disc brakes, you should follow up with your dealer ASAP.
