Prologo Zero-II Nack Saddle $0.00
Don't let your saddle slow you down. If you find yourself bogged down by a thick saddle and you are unable to shift your position as fast as you want, it may be time to look at different options. The Prologo Scratch Zero-II Nack is the perfect choice for riders who train hard to race fast.
Prologo offers three saddle profiles: round, semi-round, and flat. The Zero-II Nack is flat. Flat saddles are generally considered the best choice for lighter, flexible riders who like to move around a bit to gain power from subtle position changes.
The Zero-II Nack was designed with a base made up of varying densities of carbon. This construction allows the saddle to flex in the less dense midsection, while retaining solid support in the more densely designed paddle (widest section). The base is supported by Prologo's Nack 10 rails. Though they are a bit heavier than a carbon fiber rails, Nack 10 rails use Kevlar and small particles of aluminum which increase strength around the clamp points and add to the durability of the rails. Layered on top of the base is light foam padding, which was then wrapped in a microfiber cover.
The Prologo Scratch Zero-II Nack Saddle is available in a 134mm width and in the colors Hard Black and White/black.

Good saddle for small guys
- Familiarity: I've put it through the wringer
I've got around 6k miles on one of these, and I'm a fan (generally). It does allow you to shift position a lot, and it's going to be better for those who can put their weight onto their sit bones. It's quite flat longitudinally - maybe not quite as much as an Arione, but still quite flat, so if you want something on the back against which you can push, there really isn't much here. I did a 4 hour ride with 10+ miles of rough gravel on it last week, and my butt wasn't overly sore at the end - YMMV, obviously. If you do get pain from perineal pressure, you might have some slight issues with this saddle - I had to tweak the angle a good bit to get it just right (but I do think I've got the right angle now, so it's doable). I train and race on it, and I think it's a quality product. I will note that the claimed weight above is wrong - it's not what Prologo lists (I think they show 192g for the Nack model), and I weighed mine with almost exactly the same result (I think mine was 191g).
