Support where you need it

Fi'zi:k's Antares R3 Braided Saddle lives in a third dimension. No, really. It is the third 'A' between Fi'zi:k's Aliante and Arione saddles and it embodies comfort, flexibility, and an out-of-this-world lightness. Contrary to popular belief, a stiffer saddle is more comfortable than a highly padded one for long, grinding, lung busting rides. If you've spent any time on a spin bike at the gym, we're sure you'll agree. 

The Antares was designed for the highly flexible rider who shifts positioning like a chameleon changes colors. The flat profile combines with a slightly rounded transverse section combine to create a shape that you can move around on easily while still maintaining optimal positioning to maximize power to the pedals. The shell is fiberglass thermoplastic composite sheets which sandwich a layer of foam. This provides the stiffness necessary to support sit bones while also allowing flex at the edges to reduce chafing. Fi'zi:k's Wingflex technology, which allows the sides of the saddle to move with your legs while keeping the top rigid means that you'll transfer all your power to the pedals not to the saddle. The entire length of the Antares is covered in microtex fabric.

The weight savings on the Antares R3 is predominantly noticeable in the rails. Constructed from braided carbon fiber, they make for a 30g savings over the K:ium rails, which equates to 20% of the saddle's overall weight. The rails are made from braided carbon and then wrapped with another layer of carbon fiber cloth for even greater durability. They also have a rough surface for easy clamping. Another design feature for adding strength to the rails is the oval shaping — 9mm tall by 7mm wide. And yes, they are durable enough for everyday use.

The Fi'zi:k Antares saddle weighs in at 155grams. It is 274mm long and 142mm wide. It is available in Red/white and Black/black.

Poor engineering but great warranty

  • Familiarity: I've put it through the wringer

I have put 3 of these saddles through 10,000 mi across them. So far all 3 have had the saddle material come almost entirely unglued underneath the saddle. I wish they would clamp the saddle material with a plastic overlay as they do with other models. IMO if you train hard and race hard. Be prepared to glue this saddle back together.

Unanswered Question

Do 7x9 carbon railed saddles require a specific type of seatpost? I have a cannondale alloy post and am wondering if it's compatible?

Quality problems

  • Familiarity: I've put it through the wringer

I bought the carbon railed antares in 2011. Incredibly comfortable. perfect. However after 2 years of moderate use (probably less than 4000 miles total) it developed a separation between the left rail and rear seat connector. As a result it squeaks horribly whenever climbing or hammering. It was not involved in and crashes, I am not morbidly obese (83 kg) and it has only had 2 1/2 seasons of wear. There is a 1 year warranty. To my mind a nearly $250 saddle should be more durable. No warranty/support love from either Fizik or competitive cyclist. Will not use either in the future

Sorry to hear about your trouble. I have an Antares from 2009 and another from 2012 with no problems, both Kium rails One has sustained multiple cyclocross mishaps. I hope your experience is unique, but it seems carbon rails are more susceptible to this. I really would have liked to hear that fizik to stood behind the product.

my k:ium railed arione R3 had the shell crack, fortunately within a year after purchase (~2600 miles). I sent out pictures of the crack in a warranty claim to fizik on a saturday and had a reply on monday saying they were sending a replacement saddle. (havent received the saddle as of today, thursday but thats to be expected). its too bad the warranty isnt longer because the service I got from fizik was excellent.

That being said, I don't love the "fiberglass thermoplastic composite" shell. It has hardly any give and the level of stiffness seems suceptible to breakage under "larger" riders based on my experience and the experience of the reviewer. I weight 185 lbs which i think is about the same as the reviewer but I don't believe in the metric system so I won't bother checking. The original Arione (non R-series) I have found to be a much more comfortable and durable saddle. It doesn't have the out and out stiffness of an R series saddle but the give lets it bend not break.

i recognize my comments are for a different model saddle, but I thought I'd add my two cents about the experience of another not tiny person who had their fizik fail.

Sorry to hear that part of the rail separated. If you still like the seat overall have you tried to put clear silicone into the separated area to lessen the squeaking and maybe even fortify the area? It might be a cheap fix since your saddle is past its warranty.
