Lots of information here on the B17 vs the B17S. Just checking my understanding that the only real difference between the two is that the B17 has less of a nose - so less "T" shape. I am currently debating which one will be my entry into the non-stock saddlery world.

So far I seem to like the WSD saddle on my Trek 7.6, but I am hesitant to base a purchase on that as the longest ride I've had on that bike to date is 12 miles... I am thinking however that might be a good reason to start with the B17. I will be calling Wallingford early next week
