### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great XXL Post
  

*by N***R on Reviewed in the United States on March 10, 2022*

I needed a much longer seatpost for a carbon fiber Roubaix that I inherited. This one fit the bill. It has a nice clamping design and I find no flaws in the product. I would buy it again (pending getting it out on the road) I'm about 230 pounds.

    My OME bike seat posts bent. Not this one!
  

*by S***R on Reviewed in the United States on October 1, 2024*

I do ebike tours & rentals and sometimes I have tall, heavy riders that end up bending the post of the original bike post. This post is solid!!

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Micro adjustments a bit tedious
  

*by A***L on Reviewed in the United States on September 26, 2024*

Bought as I needed an 0 offset post. Tube is very long, but can be cut off with a LARGE wheel pipe cutter. No teeth on angle adjustment surfaces making microadjustments tricky. Overall it works fine.
