B-17, however it only became the touring saddle I had dreamt about after drilling some side holes and threading through a lateral tightening cord. Previously, after many continuous hours on the saddle I found the skirt flared and caused chafing to my inner thigh. The cord offers strength in a direction that the saddle naturally lacks, and is a simple modification that only requires a drill and some courage. I believe Brooks now offers saddles already 'laced.'

I also use the saddle with a Cane Creek Thudbuster ST seatpost (their most modest suspension seatpost). It's all adjustable and so I can get anything from a rock-hard to a soft experience. It's not particularly light perhaps, but then neither is bicycle touring.
