Fizik Antares - Lightweight and Butt Friendly


by David Schloss on Mar 18, 2009 at 8:05 PM

I have, what some might call, an insatiable lust to create a lighter bike. This pursuit, nay this passion, has driven me to replace just about all the components on my bike a few times over.


Dura Ace 7800? Been there, done that. SRAM Force, uh huh. SRAM Red, loving it but gotta ditch that heavy crank. I have been known to opt for less durable parts if they’re going to be lighter weight.


One area where I will not compromise though is in saddle selection–if my arse isn’t comfortable, I’m not going for a ride. And if I’m not going for a ride, why am I working so hard to make my bike light?

I’ve tried a few all-carbon saddles, I’ve tried some minimally-padded saddles, and again and again my posterior keeps bringing me back to the wonderful saddles made by Fizik. (For the record, they like to spell it Fi’zi:k, but that’s pretentious and weird, and really hard to type.) I’ve had a Fizik Aliante or Arione saddle on every just about bike I’ve had for the last few years and so I jumped at the chance to ride the new Fizik Antares.

At 145 grams (mine came in at 143, without the little plastic hoo-gaw that fits into the accessory slot) the saddle is in the lightweight class, that’s four grams lighter than their carbon-only Arione K1, and it’s about 20 grams lighter than their carbon-braided Arione.

Fizik claims 3.7 times the padding of other saddles in the class, and while I didn’t feel like ripping apart saddles and testing foam density, my rump was recently subjected to a competitor’s ultra-light-weight-yet-padded saddle, which now belongs to someone else.

The Antares though provides enough surface area and flex to actually support the sit-bones, the part of the body that actually rests on the surface of the saddle, and provides cushioning where it’s needed, but not where it’s not.

I’ve found it comfortable to ride fore or aft on the saddle, with the rear-deck being especially suitable for longer rides. It’s not quite as plush as the Arione, but it’s nearly so, and is flexible enough to keep me from experiencing the numbness sensation that some riders like to call “sleepy peepee.”

The saddle only comes in a black/white mix that’s all the rage in the pro peloton and it made me come to terms with my ambivalence toward white products on bikes. I think the combination of black carbon and white components is stunning, I just also know that they’re going to get dirty under my non-soigner-havinging paws and sure enough I had grease on the edge of the saddle within minutes of putting it on the bike. (I used some nice El Duke degreaser to get it off, but that’s another post.)

If you head to the Fizik site it’s hard to miss the Antares, a big splash page awaits you touting the saddle as being the “Third Dimension,” which seems somehow to relate to the fact that it’s the third saddle in Fizik’s pro lineup. Not quite as important as the actual third dimension, but they seem pretty proud of it, and for good reason.

The Antares is around $230, which makes it on the high end for saddles in general but reasonable for light-weight platforms and is well worth it in terms of comfort and weight savings. If you’re looking for a light-weight saddle that won’t hurt the junk in your trunk, the Antares is a good choice.

Nevermind the degreaser. Let’s hear about that bendy carbon seatpost.

Ah yes the seatpost. That was all my fault really. I first bought that post before I owned a torque wrench, and worse, I had it in the frame without any carbon-on-carbon binder paste. It was overtightened in my seapost clamp out on the road a LOT when it would slip downward.

I also had for some time a bit of duct tape around the post at the proper height, and I think perhaps the adhesive in that is not the best for carbon.

On a ride a few months ago I had been adjusting the height of the seatpost, got back on the bike and felt an odd sensation of dissolving seatpost.

To its credit, the carbon didn’t catastrophically fail in half it simply crumpled where it was damaged over time. I bent that post where it failed to see what the fibers looked like when a part really failed.

Seat masts are one of the industry’s epic fails.

Reason #47 why I don’t use carbon seatposts.
