I wrote some months back that I've been testing a Brooks saddle - specifically a B17 "Imperial" or "carved" model. That's the one with the big "pressure relieving" hole cut into the top. I've been using the saddle since August, and have put well over 2000 miles on it and can report a few observations.
First - the saddle still looks beautiful. The leather barely has any signs of wear. I did apply some Brooks Proofide before installing it on the bike, and I've used a cover whenever I've encountered rain, which I'm sure has helped protect it. But really, it hardly looks like it's been used. The chrome on the undercarriage is keeping its lustre. Like most Brooks saddles, it is, and remains, a thing of utilitarian beauty. The chromed rails (as opposed to painted, as on a "standard" B17) mark it as a deluxe model. The contrast between the rich brown leather and the gleaming chrome gives the saddle a luxurious look.
As far as comfort goes, something I've noticed is that the saddle remains quite stiff or hard, even after more than 6 months of regular use. It's almost as if it is taking longer to break-in than what I've experienced with other similar (non-carved) Brooks saddles. I'm curious as to whether this saddle has a different quality leather from what they use on standard B17 saddles. Maybe a tiny bit thicker? I have no way of knowing for sure - but I do suspect there must be something different about it. The Imperial model has been around for more than 10 years, so I can't understand why Brooks would be asking people to conduct long-term tests on one unless they were doing something different with it - and since I can't see anything obviously different, I can only suspect it may be something harder to detect. Different leather might be the thing.
Having said that, there could be another reason the saddle has remained so stiff. The laces along the bottom really keep the lower sides of the saddle from flexing, which in turn keeps the top firm. People will sometimes lace an older sagging saddle in the same manner to firm it up. Lacing a new saddle is probably overkill. The thing is, I typically find B17 saddles to be reasonably comfortable right out of the box, and they only get better as they break-in. This one doesn't yet seem to "disappear" underneath me as my other saddles do. I have loosened the laces on this example to allow some more of that flex that I've come to appreciate. That has helped some - but I'm considering removing the laces entirely to see what difference that makes to my comfort.
OK - so what about that big hole in the top?Some readers may recall that about 20 (or so) years ago, some doctor published a study in which he connected frequent cycling to erectile dysfunction in men. The article was widely publicized in mainstream magazines, newspapers, and even on television talk and news shows. Even though the study's findings have since been called into question, if not flat-out refuted, the result is that many saddles today come with slots, holes, channels, or grooves in the top that are designed to reduce pressure on the blood vessels and nerves that travel through the perineum.
