I use Brooks B-17 on all my bikes including my BikeFriday Pocket Pilot and my Dahon Helios P8.
Since I change the tires on the Dahon to a narrower higher pressure tire the ride is a bit stiffer.
I really like the narrower tire so I decided to try a Brooks sprung saddle. It is the same saddle as the B-17 but with the springs. Weight is not that important on that bike so I figured I would give it a shot.
Anyone else try one of these?

I have both and I really enjoy the comfort of the sprung saddle. On Sheldon's site, I read about how sprung saddles were actually the norm for every bike until people started doing club rides on bikes that were focused on speed instead of leisure. Personally, I'll probably stick with springs from here on out, although many people rave about the thudbuster seat post(which I haven't tried). Bonne Route!

I use a champion flyer S on my downtube - I have a b17on my hybrid - but I think I make send it back and exchange it for either another CFS or a b67.

I've fitted a Brooks Champion Flyer to my Birdy Touring - Probably a bit over the top as the bike is suspended anyway, but I've always found them very comfortable with virually no breaking in required.

Works for me.

I don't use a Brooks brand saddle. But I use sprung ones on all of my bikes. My old English 3 speed has a unknown leather one. My Dahon Boardwalk has a stock one with the "Dahon" logo stamped clearly on the back end. And my Brompton got one recently that is a Nirve:

for it's touch of retro California beach cruiser appeal in a Lounge Lizard pattern!

I use both a B17 and a Champion Flyer. The B17 is on my steel framed road bike, and the Flyer on my aluminum Swift folder. I like them both. For my new bike I'll probably go with another Champion Flyer though. For me, the weight saving is not as important as the added comfort of a sprung saddle.

I love these Brooks saddles - they just get more and more comfortable.

Well mine has arrived at my house so I will throw it on when I get home and give it a whirl.
