## Customer Reviews

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Good inexpensive seat post, but impossible to adjust on the road
  

*by D***L on Reviewed in the United States on June 25, 2022*

Great in all other regards, but the adjusting bolts are nearly impossible to reach with a typical multi-tool.  I have to carry an extra-long allen wrench just for this when I ride, so I can make adjustments if needed.

### ⭐⭐⭐ 3.0 out of 5 stars







  
    llegó rallado en varias partes
  
  

*by P***E on Reviewed in the United States on October 21, 2021*

llegó rallado y algunos piquetes en varias partes del tubo, se ve de muy buena calidad, un poco pesado para mi gusto pero bien. En la descripción de con retraso o recto están invertidas las imágenes.
