I'm riding a B.17, B.17N, Professional, Flyer, Imperial, Imperial Narrow, B.66 and B.72. I like them all, though you'll never see me put a sprung saddle on my Norman Rapide. On a roadster, such as my Hercules Royal Prince, the B.66 and B.72 are a natural. After riding my Fuji Sagres in CT class with a regular bicycle seat for a short period of time, I concluded that Brooks is the best saddle for me and installed a Brooks Pro.
