I used a Brooks b-17 until I bought a new Trek 560 in 1986, being assured it had a selle italia saddle,the latest, greatest, anatomically designed, ergonomically perfect seat on the market, I was confident I could let the leather one go. I soon bought some shorts, and rode until, hearing there was a later, greatest thing ever to end the discomfort--I bought that. I rode it for several years until the cover tore and bought the newest, latest, greatest thing ever and finally was relieved of the torment when that cover tore. Sick and tired of the endless merchandise cycle I bought a new Brooks flyer with springs
and found to my surprise that I was perfectly comfortable without the diapers and I honestly think that sprung saddles eliminate the vibration that frightened the doctors. Now I am not being a total retro grouch, I have gel
saddles on my winter bike, and my folding bike, but mainly because they are not intended for long rides and the synthetic is safe from the weather. My road bike, all day city mixte and touring bikes have leather and I still believe it's the best material for riding long distance. I don't use Brooks brand exclusively, I also have Velo-Orange saddles which I think are a good competitor for the Brooks brand. Over the years I have never experienced any break in discomfort with the Brooks brand, but the VO saddles can take some break-in time. It can be aleviated by loosening the tension bolt and the "apron strings" as I think they are just wrapped too tightly at the factory.
Ride leather, be happy!
