Trying to maintain pivot location and low standover/seat tube height I presume. Design is all about balancing compromises, this compromised strength over everything else.I never noticed the shock mount.
Wtf why?
Regarding the head tube.
Yeah some have catastrophically failed....
But imagine the flexing occurring during more normal high load situations that shit is probably moving under some pretty low loads
Would be fun to put it in a fixture and measure the distortion with different loads applied to the front wheel.
It's a pretty stupid design.
