This is an amazing forum....I've learned a lot, I've laughed, I've cried, but threads like this raise my blood pressure. I'm probably reading more into this that I should, but, after a few "TE flames" maybe I'm just senstive. So, take this with a large grain of salt and let me know if I should just delete it.

We all have different needs and wants from our bikes. We are all shaped differently. Sure, a B68 will work if I sit bolt upright, but that riding position won't last for the 6-8 hours I'd like to be on the bike every now and then. For the time I spend on the bike, the classic triangle riding position is better.

Bolt-upright also is not as efficient a riding position. Yes, there is the aerodynamics question, but more importantly is the ability to engage different muscle groups. If your bike is designed to be ridden upright, you're limited to riding positions and to which muscle groups you can use. My road bike gives me more positions (including one that is close to upright) and lets me switch positions frequently. Some of those positions mean I'm bent forward.

Since I will ride bent forward by choice because it fits my riding goals, I need a saddle that supports me. Because my pelvis is wide in the rear, I need a saddle that supports it. The Selle SMP model does actually support at the pubic bone as well as the ischial tuberosities. The cutout means the sensitive parts aren't squashed. For those that fit on one of the models, it is the ultimate saddle. For me it just isn't quite wide enough and a little squishy. In my quest for my perfect saddle, I've chosen to mutilate a B68. Will it work? I don't know. Is it right for Lisa and Mimi? Probably not. Is it right for DivingBiker and me? Time will tell.

The upright riding style is more accessible to people. It feels closer to riding in a car--checking for obstacles is a more natural motion. For many, it is a more stable riding platform. For those reasons I think it is popular. And, that is a great thing--it means that more people are outside and more people riding. But that riding style and purpose isn't for everyone. One size does not fit all.
