Strengths: Adjusts without tools. Light weight. No offset. Subscribes to the KISS theory, Keep It Simple, Stupid.
Weaknesses: No offset, impossible with design.
I have used this post for 5 years. I weigh 200+ lbs, and I have 12 inches of exposed seat post with a slack post angle (approaching a beam instead of a post) Some posts won't allow me to adjust my seat to the angle I need for my bike. The clamp has never loosened on me and only a couple of time has my seat been knocked out of alignment (in axis with the wheels, not the angle). I like to slide my seat forward for long climbs and all it takes is 180 degree turn of the seat (smack it counterclockwise on the nose) and the seat slides, without loosening the angle adjustment (that needs an additional 180 degree rotation). The seat adjusts in 4 degree increments, and if you rotate the jamb washer 180 degrees, you can shift the angle range 2 degrees. The post is now being sold by the original designer who can be reached at: email@example.com

Strengths: Easy to adjust (tooless), light, strong enough for my fat ass with easton tube for post
Weaknesses: Lack of microadjustability for seat angle (has the common ribbed adjustment)
I am not sure what if any improvments Onza has made to this post. The one I have is made of Easton EA70 tubing, still has the twist on mount for the seat and has Onza logos screened on (no stickers).
I started riding weighin in at 265 and am now 250 and hopfully still dropping. I have had no problems with either strength, or any adjustments slipping. It doesn't seem to flex...BTW,if any aluminum post flexes 30+ dgrees, it seems it would most likely buckle...Anyways, I tighten the head and it stays put and my seat angles has yet to slip or rotate on me.
The only thing I wish it had was a finer seat angle adjustment capability...but that may not be an issue to some...I just happen to fall between notches.
I got this as a courtesy replacemtn from LBS so I got a really good price considering its construction...
I give value a consevative 4 because I hear the retail is up there but I give the overall a 5 because it has performed almost flawlessly for me...

Strengths: this seatpost is a work of engineering art.its light, looks good and very functional.
Weaknesses: tricky to adjust.
I read the other reveiws on this seatpost and I can say that they are very acurate, with the exception of the two reviews that bashed the seatpost.this seatpost does not flex or creeks one bit unless your a super- heavy weight. As far as that other reviewer is concerned, why would you need a bikeshop mechanic to adjust a seatpost that you can adjust yourself completely tool free.this seatpost is the bomb.it works its not a gimmeck and it stands out of the crowd. 5 flamin' chilis to Onza. p.s. get one if yo can find one. if you can't your losing out.

Strengths: light strenght no clamps looks different design
Weaknesses: not so easy to adjust
Once set up right and tightend well (not over over-tighten it: it's alu!), it's the best you can get. I ride in the worst of conditions (wet, wet, wet and mud) and till now not a scratch, rust or loosening. This Easton tubing also absorbs a lot of banging too. I think it's a brilliant design; five from me!

So I borrow this Serotta from work and as I'm leaving with it one of the mechanics says, Hey let me tighten down that post for you. See this bike had a Onza sh*tpost. The kind were you twist the clamp to tighten it, smart, real smart. So I ride home (one block) and by the time I get the the seat is pointing towards the heavens. Now I had just witnessed the mechanic torqueing the piss out of the saddle not 5 minutes ago... Well this is the reason to own a mallet. I bash on the top of the saddle until level and return said bike saying, Uhh, the seat slipped so I re-adjusted it.... oh and it seems stripped. Gee, don't you just love demos? This post BLOWS, spend your money on good product: Syncros.

I also bought this seatpost for my Giant ATX-890 frame and am very impressed with it. It SEEMS like it is durable, but I'll tell you a year from now if that is fully justified. For the last two months with some crashes, and many miles, It has held up well. Very easy to use and set up without tools and it looks neat without all those screws sticking out everywhere like all the other seatposts. It doesn't bother me, but the stickers scratch off fairly easily; they're the kinds they dip in water and put on model airplanes. Also, if you scratch off the stickers completely, guess what you'll see? NADS with their checkerboard logo silkscreened on it, and it is hard to scratch off.

Onza bought this design from NADS and has been producing them for a few months now. I got one for my Giant ATX 890 because they make it in a 30.8mm size (RARE) I got it for $50 and love it. Just screw the head and the saddle is tight. ONZA makes 2 model the Lite and Pro, the only difference is the length. The Pro is 400mm (SUPA DUPA)and weighs 260grams. The only negatives are striping the seatpost threads (Hasn't happened yet I'm just scared) and there is no offset in the post like the Kalloys or Control Techs have, so it'll throw off the fit of an already set up bike. But that's no biggie.
I bought a full carbon saddle(110grams) earlier and would like to mate it to my KCNC Ti Pro Lite-8000 seatpost but the KCNC clamping system is not carbon rail friendly.
I think I need a carbon cradle or something.
Any suggestions ???
Where I can get one ?
