The Fizik Aliante Gamma Twin Flex K:ium Saddle is built with a Twin Flex shell. It's not unlike the Wing Flex technology used on the Arione saddle, but at the same time, it's totally different. The general concept of creating controlled flex is the same; Fizik uses two different materials to alter the flex characteristics of the shell. But instead of doing it on the sides (which is what Fizik does on the Arione), the Twin Flex on the Aliante has an integrated swatch of aluminized fiberglass fabric running lengthwise down the middle so the shell flexes more in that area. It's softer than a full-on plastic shell, but firmer than what you'd get from a typical cut-out saddle.

The rails are made of K:ium, a high-end steel alloy that is 8% lighter than titanium and equal in strength. The rails are marked with numeric and line gradations for more accurate adjusting. Other than the cloth portion in the cutout, the majority of the shell is a carbon reinforced nylon composite.

The Fizik Aliante Gamma Twin Flex K:ium Saddle is available in Black/white and White/black. It is ICS compatible, meaning you can use a Fizik ICS saddle bag or blinky light, and either will clip right into place on the underside of the seat. 265 x 142mm.

Glad I made the switch

  • Familiarity: I've put it through the wringer

I have ridden an Arione for a few years. I thought I loved it. I could ride all day and not complain too much. I figured it was all part of riding a bike. The Fizik website told me the Arione was right and I did not question it.

Earlier this year, I switched bikes with a friend who had this saddle. I loved it. I was comfortable. I didn't even think about the saddle. As soon as I got home I purchased one. Best decision I have ever made.

The saddle does not allow for you to slide up an down to try and find a comfy position like the Arione, but you don't need to. This saddle cups your sitting region and allows for a large area to disperse your weight eliminating hot spots. It is not so wide that it encourages chub rub (the rubbing of thighs on saddle or other parts of the bike).

If you are like me and think the Arione is good, but you still think about your saddle on longer rides, then the Aliante is worth a try.


  • Familiarity: I've used it several times

I love this saddle. I'm sorry I waited so long to replace the stock Bontrager saddle that came with my Madone 5.2.

The Bontrager Affinity 3 saddle seemed to "jam my junk" back into my body, creating an uncomfortable ride after an hour our so (and that's being kind). <Your mileage/junk may vary>

The Fizik Aliante saddle just seems to fit right. It has less padding than the stock saddle, but as it turns out, that's a good thing. I feel I can ride all day on this saddle and virtually not notice it - which in my book, is what a saddle should do - just disappear.

There may be lighter, sexier saddles out there - and I would encourage you to look - but if you're looking for a good basic "bull" (mid to low flexibility) saddle, I highly recommend this saddle.

PS - life's too short to wait for 1K miles to break in, in my humble opinion. I'll grant there is a break in period, but 1,000 miles? Sheesh. That's 3 months of riding for me. I can't suffer that long. Yeah, yeah, I know. HTFU. But not down there... at least not while I'm on my bike. :)

Solid Saddle, but better options

  • Familiarity: I've put it through the wringer

I put a few thousand miles on this saddle, and wish that I would have spent the extra money to go to Carbon Kium version. This saddle has the same shape, but the ride just isn't as comfortable as a broken in version of the Carbon Kium Version. It may take a thousand miles or so, but the Carbon version feels like it was molded for you once broken in.

Solid saddle

  • Familiarity: I've put it through the wringer

I've been riding one of these for the last 5000 miles. The saddle gives you a firm platform, with multiple positions to work with. It's pretty conformatable, especially for riding up on the brake hoods. Maybe not the greatest for spending a long time in the drops. The nose is a little wide and sometimes my legs rub on it.

The saddle is pretty durable. Before I installed the Aliante, I had broken the rails of two other saddles. 5000+ miles later and this saddle looks like new.

Fizik Aliante Gamma test saddle

Testing out a new Fizik Aliante saddle. After 80 miles of test rides, this is a keeper. I'm going to try the versus edition of this saddle and buy the one that's more comfortable.

Fizik Aliante Gamma test saddle

does the Gamma come in different widths -...

does the Gamma come in different widths - need 143

This saddle is 142mm wide so it should fit just fine.

Also, when I was looking for Fizik saddles I used there spine concent tool. Even though it is a little cheesy with the "Find the animal within you" tagline, it will put you on the best saddle for your body type.

You'll be fine on the Gamma if you're looking for a 143mm width saddle

Sitting Pretty

    I ordered this saddle to accomodate my sore behind on my Pinarello Dura Ace I just got. In fact, there is no difference between this saddle and the stock saddle. I am just getting used to the original one and it will probably be fine. The Fizi saddle is made well and good looking, but again so is the original one. I returned it for a prompt refund.

    I want to buy this Fizik saddle but I see...

    I want to buy this Fizik saddle but I see that you are not offering free shipping for this item. Could I get free shipping if I buy this saddle from you? Ebay is offering the same saddle for $20 less, but I would prefer to buy this from you. I've bought my stuff from Backcountry before and gotten free shipping, if not its ok, thank you.

    Please give us a call or jump on livechat and talk to one of our gearheads. Thanks

    Great Saddle

      This seat just made my day the first time I rode it. Great shape that did not have any hot spots, or cause any chaffing. Provides much greater cushioning than might be expected. Looks great on the bike as well.
