### ⭐⭐⭐⭐⭐ Quality setback seatpost
*by K***R on October 25, 2025*

My old saddle needed a zero-setback seatpost; when I changed to a saddle that needed a setback seatpost, I ordered this. LBS had junk. This is solid, easy to adjust, and holds the saddle firmly in place. Highly recommended 27.2 seatpost.

### ⭐⭐⭐⭐⭐ good seatpost.
*by M***. on June 27, 2026*

no brainer install. perfect.

### ⭐⭐⭐⭐⭐ Does what it's designed to do
*by D***A on June 20, 2023*

This is a rigid alloy post. It is not meant to absorb lots of road vibration. It holds the saddle in place with minimal fuss for installation. It allows for easy, precise fore-aft and tilt adjustments to fit the rider's needs. I was able to install the saddle without removing the bolts: loosen bolts, remove lower cradle, slide upper cradle onto rails from the rear of saddle, and gently wiggle lower cradle back in. On my setback model, the front adjustment screw is slightly more difficult to access, but I was still able to fit a bit with extension in for my torque wrench.
