Fizik Antares R3 Road Bicycle Saddle with k:ium Rails

Titus McNamaraTitus McNamara: I'm running this saddle on a 50cm Dolan PreCursa fixed gear. I use the bike primarily for commuting and playing in traffic in the city.

However, one of the challenges of being a short dude is finding bike components that fit you. Saddles are no exception. Especially when you have wide set sit bones like me (139.7 mm). Which means that the standard sized 140ish saddle isn't quite wide enough to support my dump truck.

I found this out the hard way after purchasing the Brooks Cambium C15, which is only 140mm wide. I hated that saddle. It seemed like no amount of adjustment could make it feel comfortable.

Fed up, I went looking for a replacement and found the Fizik Antares R3 large. The word "Large" is kind of subjective here because it's only 152mm wide, but those extra 12mm make all the difference. I pulled this saddle out of the box, installed it, set the nose to -1 degree as per Fizik's recommendation, then took off on a short ride.

And It was heavenly.

There was no weird pressure in my perineum like with the Brooks and no sliding round. Instead, I was treated to an overwhelming sense of stability and control. Even when I took...

zimpapatren: I replaced Selle Italia Model X to my Canyon endurace bike. Apart from getting significantly lighter, the bike feels more comfortable. Despite not having a hole, it feels safe for prostate while riding.
My rides are mostly climbs with duration of 3 hours.
It looks good too and feels of great built quality.
Packaging was superb as well.

PC Mountain: I’m a longtime user of the Fizik Antares. I’ve tried several other brands and types including the channeled Antares but I’ve always come back to this one. It’s my fourth one. My other ones are older generations and they use a slick material for the covering. I’m not a fan of this new material. It’s tacky so you don’t slide as much. Personally I like to be able to slide around and easily change my position. That being said, this saddle is still more comfortable than anything I’ve used so I’ll stick with it. The fact that it’s reasonably priced is a bonus.

まーちゃん: もとのサドルは１時間も漕ぐとお尻が痛くなってしまいました。メタボのわたしには小さすぎたのだと思います。
これに変えたら、2時間走ってもお尻が痛くありません。……人それぞれで、合うものと合わないものがあるのでしょうね。

marcg: Got this seat to replace the narrow, flat stock seat on my Scott Solace road bike which left my nether regions numb on rides of more than a half-hour. The R3 Antares is Fizik's mid-range road bike seat for what they call the "Chameleon" body type (more on this later); I'm very pleased with it. No more numbness even on multi-hour rides and it's comfortable.

The biggest improvement over the stock seat was simply getting a seat of the proper width. The seat should be wider than the spacing of your sitz bones ("ischial tuberosity," see Wikipedia). Search for "measuring sit bones" on the web to see how to measure their spacing, then buy a seat that's a few centimeters wider than the measurement. The Fizik site lists seat dimensions including width. Makes a huge difference to have your sitz bones supported by the seat rather than having the seat wedged between them.

The other improvement was getting a seat with a slight uptilt at the rear to rotate your hips slightly forward, reducing how much you have to bend at the waist to get into a proper riding position. Fizik designs for three body types: Snake (very flexible, seat style Arione), Chameleon...

Chaz Turbino: Fizik's website indicates the R3 K:Ium uses a glass reinforced nylon shell, yet it strangely looks like carbon, like the one on the R1. The VS K:ium is advertised as using a carbon reinforced shell, but it looked like plastic given the numerous plastic markings on the shell!

I used their app and got fitted into the Antares R1 and R3. The K:ium alloy is proprietary and Fizik refuses to indicate what type of material it is, but I found some reviews/articles indicating it is a titanium alloy with more chromium and silicon added to it.

Regardless, the R3 Large is very lightweight and seems to be more comfortable than expected. My sitbones are 110mm apart, but the Antares is flat enough to not really hurt them. The Antares VS is more curved and seems to aggrevate my sit bones.

Overall: 5/5 stars
