If it suits you, it will surely look good on the Sirrus. I am trying out a Brooks Swift (steel rail version - more appropriate for my tax bracket) to see if it will be more comfortable than the similar VO Model 6 that I have on my Bridgestone RB-1 now. The VO saddle looks nice and is fine for short rides, but after about 20 miles, it starts working on my sit bones. 35 miles is about all I can do on it. The Swift is a little softer and should take my shape quicker, but I suspect that it will turn out that the real problem is that the saddles are just too narrow for my sit bones. The depressions on the Model 6 are at the outer edge of the seating area, right up against the rivets across the back of the saddle. The Swift is the same size, 150mm wide. As much as I like the way the slimmer profile looks, I think I may need to go back to my proven favorite, the B17, which is 170mm.
