If you already know about this I am sorry! But I just found out and this part is on my bike! I won't get to ride for a week at least. This is for bikes after November 1, 2005 this is a voluntary recall by shamano.
potential hazard-subject 'quick release' skewer could fail or break! This happens while biking!
here is the # cause there is a lot of info on the thing I got in the mail. 1-800-353-4719 or you can go to bike.shimano.com and the contents of the notice can be found there. I am pretty bummed my bike is only 2 months old i have to go back to my old bike. But I would not want to put myself at risk!
