Ok stupid question (2) what is meant by the "twist" of a saddle?
The twist is basically a description of the width of the seat. I like a wide twist but lots of people prefer a narrow twist. I think it comes down to personal preference and pelvis width.
Not quite. There are three critical "widths" for the rider -
Twist - under the crotch and, with an English wooden tree, the point where the rails change direction, they come inwards from the pommel, and then "twist" back out again under the rider's pelvis, ideally the pubic arch.
Seat - under the seatbones, the widest part of the overall seat in many but not all cases. If you think about it, for a saddle to really fit a rider, the widest part must be the right distance from the narrowest part to fit a particular pelvis...the triangle of pubic arch to seatbones.
Waist - the rider's inner thigh, an area that needs adequate support (many saddles can be too narrow here and this is a common cause for gripping with the knee) but for most riders wants to not be too bulky. With a treed saddle an independent panel, not sewn into a sweat flap or mono flap, and a cut away sweat flap if there is one, will allow the thigh to drop better.
All three have an effect on the rider's ability to sit in neutral in comfort, and all three can contribute to pushing the pelvis back, or tipping it, or pushing the leg forwards.
