3T Ionic Seat Post Issues

I bought the above seatpost from a member of this parish who assure me he never had an issue getting his saddle level. Any owners of the 3T Ionic 25 Stealth Seat Post that can help me in getting my saddle level as it's driving me mad!
It has two cogs inside the post that allegedly allow you to fine tine the level of your sale but I can only get it to sit nose up or down, not level.
The video on youtube says if it's too high you rotate the inner ring 1 cog then the outer two (or vice versa) but looking at the gearing on the teeth they look identical so if you put the inner one forward one tooth & the outer back by two, it only has the same effect as moving one or the other forward or back one space.
I have mailed 3T for an answer but they have failed to even acknowledge my mail so I am now stuck with an expensive seatpost that I can't get my saddle level with - doesn't seem right to me particularly for a brand that is perceived as 'high end' equipment.
One thing to note is that my top tube is sloping but surely that shouldn't affect it? I have tried several saddles (Selle Italia, Selle SMP, Fizik, Specialized) and some I can get more level than others but nothing pan flat.
Any suggestions gratefully received!

Gutted you're still having trouble with this.

Does it matter whether or not it is level? Doesn't it just have to be the 'right' angle?0

Parlee with this seatpost showing level saddle
Bad angle but saddle on post: 0 -

I suppose it doesn't have to be exactly level however I have always felt I'm sliding forward if I have the nose down or always trying to shift forward if I have it pointing up.
Either way would be nice to get the saddle level if I want it & not have to settle for slightly up or down.0 -
Thanks for the photo's Duncan maybe I should keep fiddling with it & try riding with it in different positions.
Just so frustrating as the video on youtube seems to make it look so easy and you can't get any other information anywhere else.0 -
You are most definitely doing it wrong
But I sympathise - when I first got an Ionic with the funky double cog I had the exact same problem - and trawled the internet like you have - and eventually had a Eureka moment - and now all is good.
From memory, there are two cogs (of course). One of them makes a 10 degree adjustment in either direction, the other is a 9.5 degree adjustment in either direction. So by using both (in the correct way!) you have a half degree adjustment, i.e. 720 different positions - certainly enough to achieve perfect alignment.
What you are probably doing is moving them both together, or moving them both in the same direction. What you need to do to achieve a half degree adjustment is (for example) move the 10 degree ring forward and the 9.5 degree ring backward - to achieve a net half degree movement.
Apologies if I have some of that slightly incorrect, I'm not next to my bike at the moment
But hopefully it helps you get the idea.0 -

Yes, Pauly has it correct.
The user manual for the Palladio (old version of the Ionic) has more details if you're still having trouble.
http://centralbike.co.th/download/palladio.pdfImportant note: One-half of one degree is an exceptionally fine adjustment. As a rough guide, when using a spirit level to determine saddle angle, ‘half a bubble’ out of level is about 2 degrees. In this case, you will need to rotate the outer spline by 4 teeth in the appropriate direction, and the inner spline a corresponding 4 teeth in the opposite ! direction.
Basically, what you want to do is take out the whole mechanism (i.e. leave the inner bit inside the outer bit) get as close to your desired angle as you can and then use Pauly's instructions to fine tune by 0.5 degree increments. The outer splines are in 9.5 degree increments and the inner splines 10 degree increments, so the easy way to visualise what you're doing is to remember that whichever way you're rotating the inner ring is the way that you're tilting the saddle.
It's easy when you know how!0 -
Pauly / Buck - thanks so much for your replies & the link to the manual, it makes more sense now. I'll be certain to give it a go this evening & see if I can get my preferred angle.0

Well after another 20 mins and rather a few choice adjectives, I now have a level saddle!
Easy when you know how I guess ;o)
Thanks for the help guys.0 -
