Fizik's research into its next generation of mountain bike saddles revealed something interesting: riders of 29ers sat differently on their saddles, farther back, often in such a way that they weren't supported the way they needed to be for optimal comfort and power transfer. The solution they devised was the Fizik Thar, a dedicated 29er saddle that better aligns riders over the bottom bracket without forcing them to shift the saddle unnaturally far forward, and this Kium-railed version keeps price down without sacrificing the support the saddle was designed to deliver.
This Thar, of course, gets Fizik's proprietary Kium rails, a light but durable alloy that serves to reduce cost while only adding a tiny weight penalty over the not-yet-released carbon-railed Thar. The shell of both is comprised of a carbon-reinforced nylon that incorporates Fizik's TwinFlex platform, a dialed flex pattern that allows movement of the shell's "wings" to accommodate natural pedaling motion of the legs without impeding the saddle's supportive structure. The Thar also gets a replaceable insert under the nose that can be swapped out to either firm-up or soften the saddle's overall demeanor. The flat profile of the Thar allows easy movement fore and aft on the saddle for navigating technical situations, and at 195g, the seat's weight is comfortably within the definition of light for a dedicated mountain bike saddle.

Flat as a board
- Familiarity: I've put it through the wringer
This saddle is almost completely flat. As far as I'm concerned that's the business. In addition it has a fairly narrow profile with a shortish nose and teardrop back. All that makes it easy to slide off the back when you need to.
I'm a New England rider. That translates into mostly tight wooded terrain. The fallout of that is I don't ever get to sit for very long at all. For my purposes this saddle is perfect, it has a really usable shape and great power transfer (it's stiff). I can't speak to its 29'r specific properties. I'm using it on a 27.5 +. I also can't tell you what it would be like if you had trails where you had to sit and grind it out for long periods. But for me, A. maybe A+.
Comfortable and sporty.

I'm using this saddle with a Jet9 RDO and it looks great. I'm not sure how Fizik designed this specifically for 29'ers but ergonomically it is comfortable, firm and suits this frame very well. I like a saddle that disappears when I'm riding - it's not something I want to think about.
