Noticed on my last ride my 2010 mission 1 frame is starting to crack at the weld where the top tube and down tube meet the head tube.
I slightly modified the frame by cutting the top of seat tube down 3/4" so I dont know about warranty? I can see them saying its modified and doing nothing but at the same time the seat tube has NOTHING to do with where its cracking. Worth taking the bike in and being without it for awhile to see if DB will warranty it?
