Is it possible that this saddle could fit as the flaps are extra long?
I would probably get in trouble if DH new I was even thinking about buying another saddle, but I have always yearned for a BD and this one actually fits my budget.
Someone tell me my behind is just too big so I don't have this one shipped to try
I couldn't get the link to work but I am going to venture a guess you are looking at the saddle with the 5A flap. I agree the PJ's by Bruno Delgrange run a hair small. The original is the Bruno Delgrange Virtuose so it has a deep seat which will also make the seat feel smaller.
I wouldn't try it. Most Prestiges marked 17" run large and actually measure closer to 17.5". A few of their models measure a true 17", but it's very common for them to run large.
By contrast, Delgranges tend to run small, so a 17" Delgrange is going to ride more like a 16.5". Notice how far forward the pommel nail is on that Delgrange, and you'll see why Delgranges tend to ride smaller than they measure.
