yes there's a fair few of us use them in the UK for timetrials, and some for roadracing too.

I've got Adamos on my tt bike (tribars, lowpro frame) and my turbo/training bike (drops, normal frame). There's a video on the ISM site which shows you how to set an Adamo saddle up properly.

It takes pressure off the front pubic bone/soft tissue area and also gives a space for your soft tissues to sit, uncompressed.

Sitting on the seatbones feels a little hard at first but you soon get used to it provided you set the saddle up properly to start with and then tweak if needed along the lines they suggest.

Under pressure I do tend to slide forwards a bit but looking at other people under pressure on bikes, so do they. Sliding forwards isn't too uncomfortable, less uncomfy than sliding forwards on a normal saddle.

The Adamo saved my racing career, I could not sit in the tt position for any length of time (3 miles was enough before I'd start wriggling) with any "normal" shape of saddle, with or without cutouts. With the Adamo I do all distances up to 100 miles.
