Review: 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)
Review: 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.
