Alright, the other difference (which i'm blown away hasn't been touched in the last three pages) is that the iro and pake are production bikes. they make thousands of them exactly the same every time. the DW bikes are CUSTOM - you are measured, think and work through the exact fit of your sizing, your riding style, and the events you'll be competing in and you get something that's tailored, not mass-produced.
that's a HUGE differnece.
