My take on the ISM Adamo Saddle? It is strong medicine.
If you are already passing on all points of this saddle comfort and acclimation checklist:
I am wearing high quality bicycle shorts (not tri shorts) preferably bibs.My shorts fit very snug. The fit is tight, supportive and accurate. I do not wear any undergarments of any kind under my shorts.I use chamois lubricant such as Assos or Chamois Butter regularly.My bike fit and positin has been professionally verified as optimal by a fitter with experience whom I trust. I have adequate saddle acclimation of at least a season of performance oriented road cycling of over four hours average per week on the bike over the course of a year. I have already used- and found unacceptable even with all of the above factors in place- more conventional saddle designs.If you pass muster on those points you are an Adamo customer.
Why the phalynx of qualifying questions? The ISM Adamo is strong medicine- like chemotherapy. You don’t get chemothrapy unless you know you need it. You don;t get it for a chest cold, you get it for chest cancer. The Adamo is the same.
On the Adamo you are going to a shorter saddle that works by partially removing weight from the saddle area and redistributing it forward. If you read the instructions for the Adamo there is a reference to angling the nose of the saddle slightly downward. That shifts or slides rider weight forward and changes the center of gravity of the bike, placing more weight on the handlebars. Bikes are “upside down” vehicles that weigh about 20 pounds and carry a nearly 200 pound payload very high on their center of gravity. To make matters more complex, that payload is in constant motion (pedaling) and shifts around a lot (climbing, in the saddle, out of the saddle, etc.). When you go to the Adamo the deal you are making is giving up some saddle length in exchange for a redistribution of weight and an expected increase in saddle tolerability. That’s a hard bargain.
If you search on this website over the past three months on the ISM Adamo saddle you will find a number of threads where people bought them and had initial discomfort and started asking “How long does this take to break in?” A more operative questin may be, “How long do* I* take to break in?”
The ISM Adamo is a fine saddle alternative when more conventional designs aren’t working. It is not a viable substitution for good saddle comfort habits as listed above.
Talking out your a%* again, I see…although for the subject, I guess that’s appropriate 
You make it sound as if an Adamo is some sort of “last resort”. Bullshit. It should be the first resort if you ask me. The vast majority of the time the reports of “initial discomfort” typically boil down to some sort of error in setup (i.e. trying to sit too far back, not having the rails level as a starting point, etc.).
Weight distribution between the saddle and bars should be unaffected when you get it set up correctly. Heck, for me, I probably put MORE weight on the saddle after switching to an Adamo than I did before using that saddle…because I *could *without it feeling like my “manly bits” were being shoved up towards my throat!
For any “moderately aero” position, either on a TT/Tri bike or a road bike, the Adamo just plain “makes sense”.
If you only knew of how many people (who were perfectly “ok” with they’re “standard” saddle choice) I convinced to give an Adamo a try who basically came back to me with reports of epiphany-like experiences…
