I have three bikes which have brooks B-17 saddles on them, so I guess you could call me a fan. One of the bike/saddles has 14,000 miles on it now, and the saddle sags a little in the middle, I have tightened the bolt, and it has made it better, but the saddle is not what it once was. Each of the other two have about 4,000 miles on them. One thing that I find surprising is that the newer of those two (one was bought 2 years ago, the other years ago), looks almost new, and is still very hard and firm. The older one is visibly more broken in, and is more comfortable. I wonder if the quality of the leather used hasn't changed between my various saddles.

Lately I have been experiencing lust over the Gilles Berthoud saddles - OMG are they gorgeous. I got a chance to see and caress one in person and have been dreaming about it ever since.
