Negative. The Adamo Prologue supplied with the P5 is too wide (for me) despite riding not far off the rivet, mainly, at my typical race efforts. In fact when I'm really hammering hard in aero, well above FTP, I tend to almost fall off the front due to a strong 5 - 7 o'clock compared to my compressed 11 - 1 o'clock. I've gone through a reasonable repertoire of modern saddles over the last few years in search of one that plays nice with my twig and berries yet doesn't impede my stroke by way of loss of comfort over the long haul forcing me to eventually splay my legs wide to find relief from chafing. An Adamo Breakaway (slightly narrower than the supplied saddle on the P5) was okay for me, just not awesome for my IM-length efforts. I rode a Cobb V-Flow for half a season; wasn't my cup of tea. I've used a Fizik Arione; too convex at the taint/nose contact point. Adamo might be #1, just not my #1. The Specialized saddles seem to fit my body well however.
Not to drift too far from the intent of my post, the optimum width of the nose of a TT saddle for me is 40 - 45mm, untapered for 5 - 7 cm from the nose aft. The Arione is 40mm with a very long, gradual taper, but the shape is not flat enough for my comfort. The Specialized I use on my S2 is 45mm with almost no taper for a good 5 cm from the nose and is quite flat making it great for extended riding on the drops and with an aero setup. The Adamo Prologue, at its narrowest is 60mm at the rivet, and has an immediate widening (i.e. continually tapers all the way to the nose), making it simply too wide for my body.
Back to the original post. My question to Damon still stands: are rail clamps that will accept Specialized FACT carbon rails, or any other non-round rails, available?
Dave I'm also not a huge fan of the saddle (came on my P5 as well) - same issue with nose width, but I've gotten used to it and now I like it.
I did do the nose narrowing trick you might want to try: Drill holes on the INSIDE of the front nose pieces and put a strong black ziptie there and cinch it down. Narrows the nose down a bit and helps some. Basically with this, I find this saddle great when riding in the TT position, but not for general riding when sitting upright - still too wide for me, but I rarely ride the TT bike except for races.
