Chipped, but I can't be mad...
This is quite a nice seatpost. It came with a small chip on the clamp, making me think it was a returned item, but it's such a nice seatpost I can't even be mad about it. It has a seemingly generic tilt adjustment mechanism but it works incredibly well. Micro adjustments are a piece of cake. And it's quite sturdy, as well. I definitely recommend! (And the chip isn't so bad that a black Shapie marker can't take care of it)

Great seat post with zero setback (if that is what you need)
I needed a seat post with zero setback. This was perfect and has allowed me to get my bike dialled in to match a fit I had done on a different bike. Easy to fit and solid.

I find this style of seat clamp is easier to adjust
I find this style of seat clamp is easier to adjust tilt and stays more secure then others. I would buy again!

Another great Zipp product
Fits 27.2 as designed, looks great and the 2 bolt system makes minute angle adjustments very easy.

Great fit for me
Needed a zero offset basic seatpost to replace my stock one. Bike is a 2003 lemond big sky sl. Lighter than OEM too.
