I've had two rockys in the shop this week and both had cracks in the same place. It seems to be a problematic area. Both of these were 06 bikes and might be a problem for 06 and older. Both of these were cracked on the seattube where the lower linkage is welded to the frame. It is worth checking out if you have one of these bikes. Rocky has a five year warranty, so in most cases, its covered and rocky will send you a new one. It's just worth checking.
