The last thing in the world I want is an adjustable seat.
I took me a good few months to find my groove on an ISM TimeTrial but I have found this to be true of all saddles. When I first started riding (normal bikes) I thought you just sat on a saddle and that was that, the pain was my noobness. Then I thought I had learned how to sit on a saddle. Two years later I realised I had not, and found a new way to sit on a saddle. Then I was comfortable for hours.
So, that’s just a very long way of saying that saddle vendors need to stop selling saddle fittings and learn how to tell people how to sit on their products.
