I have a B-17 and it looks great. The rivets kill my arse though. I've tried sliding the thing back and forth but the rails are short. They don't leave much room for adjustment. I tend to ride more upright and heard that the sprung saddle(B-67, not sure if this is the correct model #) would better suit my riding style. Anyone have any experience on one of these? Do tell.

I have two Brooks saddles: a B17 on my fixed gear Ice Bike; and, formerly, a Ti Swift on my summer fixed gear.

I took the Ti Swift off my summer bike, not for comfort issues, but weight issues.

Otherwise, I would describe my B17 as the most comfortable saddle I have ever ridden, although it took awhile to soften up; and, I grease and oil my Brooks more than most people do, but it works for me.

I have found when changing from one saddle to another, I need to experiment a little with the new saddle in terms of height and fore-aft position in order to find the "sweet spot."

Also, all my other saddles have a perineal groove, and when I first rode a Brooks it chafed my perineum.
Now I go back and forth between a grooved saddle and my Brooks without any discomfort.

I have the cheapest model: a black B17 and I'm loving it. At first they are flat. With time, they will be "stamped" with your ass. That's when you won't want to go back.

One thing I love about them is that they are somewhat cooler (as in temperature).

Back in the day, before the invention of planned obsolescence, all bike saddles were leather.

Downsides: Break-in period, although I can't say it has been a problem for me, and making sure you protect it from the rain (put a plastic bag over it when you leave it outside).

It came today...

LOL

thank you so much.

I have a Brooks Professional that says Pre-Softened on it. Pre-Softened my lily white ass. I've had it on there for two years and just took it off last week and put on a beat up Selle Flite. Ahhhhh. But it did look cool.
