The stem of the stoker is just above the seatpost clamp and under the top of the lower part of the dropper. So here handlebars don't move when the seatpost moves.
In technical stuff the fact that the center of gravity is lower and further back makes a difference when turning, dropping, riding over obstacles. That's also why i like to
ride the tandem front suspension with more sag. It makes i also easier to touch the ground with one foot. I don't think the lateral torque will be the problem as long as she's sitting down.
The torque of the stem could be a problem, but i think the torque o a seat post clamp is higher than the torque of the stem. I'm big(198) she's 1.52. The dropper makes it also easier
to make restart in a climb or a steep downhill.
And onroad I will go faster down in a more secure way. We ride a fullsuspension. We us more than 50 codes for warning her what to do or what's coming. The fullsuspension makes
a lot of things easier, more comfortable and more fun for her. The bike is also very stiff.
