Repaired Trek Madone

About six weeks ago, I found a crack in the drive side dropout of my 2005 Trek Madone. Now this frame has been repaired a couple of times to fix cable stops that had become detached from the frame. But this looked a lot more serious. 

So, chapeau to Trek. They have removed the cracked drop out and inserted a brand new one into the carbon chain stay and seat stay. I don't know how you do that without damaging the carbon tubes. And all this was free of charge - including postage - under the lifetime warranty. Despite obvious signs of heavy use. No quibbles. Chapeau again!
