i was cleaning my bike up a while ago and found 2 large cracks on my frame. they are on the down tube about 4 inches away from the weld. they havent started due to a dent or anything! i cant see how my riding could have done this to the frame! is there anyone i can get in touch with. i bought the frame from bikedock and the warranty ran out about 3 weeks ago. i am very disapointed with this because it isnt my fault. if the crack was on a weld etc then fair enough but just on a piece of tubing! all advice welcome. i also have pictures if anyone would like a look. thanks Dave
