This is not because the rear triangle flexed, but because the
chainstays were a super-long 46cm and the overall wheelbase a
super-long 44". The extra-long chainstays move the contact patch back
away from under the ****, resulting in a much smoother ride, regardless
of flexibility. This well-known effect is geometric, not elastic.
Overall wheelbase, bottom bracket height, and wheel size are similarly
involved:
