Tourist in MSN

I have a B17 and found it to be a bit too wide and flat for my anatomy, my B17 now is permanently on an old hybrid that is permanently installed on an indoor trainer, I can sit upright on that bike and read or watch tv. But my anatomy does not agree with the shape of a B17 if I lean more forward like I do on a road or touring bike.

For bike touring, I prefer a shape like a Brooks Pro, it is a bit narrower and the back is a bit more rounded, less flat. Or the Conquest that has a shape very much like a Pro with springs. The Conquest is what I use for touring or other long distance riding.

I bought a C17S at a great clearance price, tried it for maybe a total of 100 miles (~150 km) but the one I got was rock hard. The people that had C17 saddles that had suggested that I try one all had softer ones, so maybe mine was a one off problem with stiffer rubber. I have quit using it and bought a C17 weather proof one a few weeks ago, have not tried it yet.

To answer your question, on my new C17 weather proof saddle the part of the rails that clamp onto the seatpost on a C17 is much longer offering more adjustment than the rails on the B17.

C17 I think is very similar in shape to a Brooks Pro or Conquest, not as wide and flat as a B17. So, if you have a B17 and like it, you might want to visually look at a C17 before you buy, it might not have the shape you want.
