Apologies to Brooks riders....I know I'm stepping on a sacred icon 8-) but I put over a 1,000 miles on my B-17 and never really appreciated it. Adjustments up and down, fore and aft just didn't get it. Sliding around on it, sliding forward especially unless I tilted the nose to the point of sliding backwards. And I consider my bike fit and set up fairly dialed in. Someday I might try a Team Pro. A riding friend has had his Pro in use off and on for 27 years. It looks like last year's dried road kill but still works for him. Anyway, back to my plastic shell Regal. So many people report their love for this saddle, I'm sure I'm a lone voice here. Wouldn't you know, I get born with the weird butt!
