The Trek dealer that fitted me, said there is this cradle effect you sit in. He first measured me, then adjusted some, then had me ride while he was watching. Asked where I felt the saddle etc.. I went 10 miles last night and felt nothing but comfort. Same on my ride today, that's what the pros are for.. Best fit I've ever had, and under 50. dollars.. (cost of the new seat) already had returned the other..
