0 Degree Seatpost vs. Forward Seatpost

A lot depends upon how much setback your current seatpost has, what your ST angle is, and where your current saddle sits on the rails.  That said, 8cm is a lot - chances are, you'll need some sort of forward post.

In addition to the profile offering, take a look at a Thompson layback post.  You can easily reverse the head on these, and use them as a forward post.  Plus, the two-bolt head design will allow infinite adjustment.

Where are you now?

What kind of bike do you have? Road?

Do you have photos and measurements of your fit?

Can you measure your rails and see if at 0 you can get 8 cm with 0 seatpost. Are you all the way forward on your rails?

Moving up 8cm (over 3 inches) seems like a lot and moving forward will change the handling of the bike.

I think the basic idea is that you only have to get to 77 with your Adamo, which will hopefully make things a little easier.

Right now, I am at 70 degrees.  I have a kestrel road bike.  I have a video of my latest fit here:

My seat height is 75 cm. 

I have a pic of my rails showing that I am as far up as possible with my current seat post here:

If I can get nearer to 80, like even 77 as someone suggested, that would be great.  Thanks for any advice you can give.

Double check that.  Most road bike STs are in the 73-75 range  It may be that you don't need to get as far forward as you thought to hit the angle of your dreams...

I took a look at the pics and videos of the seat and your fit. The seatpost has a 1.5 to 2.0 mm setback. The video shows you are getting close to having your knees hit your elbows, so there is not a lot of room to move forward without also considering a longer stem.  It does not look like the present seatpost is reversible. The video shows the leg could extend a little more. The nose on the seat is tilted down too far, so you could end up sliding forward. Strive for nearly horizontal and it will improve the leg extension and knee to elbow clearance simultaneously.

As far as seatposts go, I have used a Profile forward, a Thompson Elite revesible, and a Bontrager reversible. The Profile offers the greatest forward distance, 4-6 cm. The Thompson and Bontrager offer 2 cm forward. The Thompson is the lightest. The Bontrager has a side bolt for easy position changes without removing the seat bag. I've enjoyed them equally.
