I got this seat to replace my Specialized Romin saddle, which I love, but I have broken the rails on three different seats over the span of about 4 years - broken where they connect each time, not the rail itself. Anyway, I got the PRO Turnix because it was the closest shape and size to it. It is very close indeed, just not in comfort. The sides of the seat are a hard plastic that sticks out and rubs on your inner thigh to the point I just ordered a new Romin so I never have to use the Turnix again. I'll just budget to buy a new Romin every other year. The construction of the Turnix seems fine and maybe for some it works for them.
