I haven't tried it, but I'm sceptical. There are several points in his product presentation that I can't see the base for:
- It straightens out the legs stroke correcting the outward movement of the knees and eliminating the related injuries. As a further result of this, the legs work perpendicular on the pedals, maximizing the efficiency of the stroke and the overall performance.
I just can't see the mechanics here. You'd have to ride a really wide saddle for this to be an issue. For a regular narrow nosed saddle there's virtually no difference. The bulk of cyclist's knee troubles stems from unsuitable pedalling technique (people grunting it out on too heavy gears), insufficient attention to training (too one sided, no stretching etc) and to a lesser degree equipment related, bike fit, crank length, crank Q-factor(pedal-to-pedal width) and pedal tilt. There are parts called knee savers which'll move the pedals wider apart, and there are wedges that go between sole/cleat to adjust shoe angle.
- The UN~Saddle® prevents the pushing forward of the upper body, ensuring proper and continuous ischial support.
This one is even more questionable. Get the fit of the bike right for your type of riding, and you won't be sliding forward regardless. Sliding forward is generally seen to be caused by having the saddle too far forward, or the bar too far forward, or both. Saddle too far forward reduces the retaining leverage offered as you push down on the pedals, causing a gradual slide forward. Putting the bar too far ahead puts your upper body too far ahead. Even if the saddle/pedal setup was right for one setting, increasing the "overhang" will also increase the need for an increased retaining leverage to maintain balance.
- This also enables various positioning on the seat, for different cycling situations, without need of rail adjusting.
Can't see anything unique there. Correctly fitted, a traditional saddle will also allow you to move around a little.
To me, it all sounds like he's comparing a badly chosen saddle on a poorly fitted bike against his seat, on an ideally fitted bike. Not really fair is it?
- The UN~Saddle® offers an ideal supportive surface, an efficient fulcrum for the legs and the body to "lean against" rather than to "hang from".
Anyone who's "hanging" from the saddle is Doing It Wrong, and/or have a terminally poorly fitted bike.
- It also prevents chafing of the inner thighs.
Only times I've ever been troubled by that was when riding while wearing a climbing harness, or a longish ride in brand new jeans.
- It improves agility and quick reacting in technical riding.
This is also very contrary to the general opinion. Even BMXers, who do just about all their riding out of the saddle, prefers to have one fitted. In technical riding you're usually out of the saddle anyhow, but putting your leg against the side of the saddle provides some leverage and control.
And try as I might, in these days of blogs, homepages, tweets ASO, I (=google) can't find a single instance where those people who have given such glowing testimonials say a word about that saddle outside a page trying to sell it.
Noseless seats have been around for ages, and although they have their sworn followers, they're certainly not taking the world with storm. They can probably be part of a proper bike fit and help those who suffer from numbness.
But in your case, with a diagnosed issue quite a few inches higher up, the only benefit I can see is the so-so suspension. In which case there are suspension seat posts that are more tuneable in stroke/firmness that will take your regular saddle.
And for riding more upright - that won't happen just by replacing a saddle, you'd need a shorter/higher stem too to get there. zero offset seat post can contribute - but there are bike fit complications to that.
Maybe look at a Rans crank forward bike?, or a full-blown recumbent?
