### ⭐⭐⭐⭐⭐ 







  
  
    Perfect seat post clamp
  

*by M***E on Reviewed in the United States on August 25, 2017*

This is the third seat post clamp I bought, the first one didn't work because the attachment holes for the rack extended below the piece and hit my frame, the second one worked but was big, ugly, and not very secure in my opinion, this piece is perfect. Looks good, discrete, simple, and gets the job done.

### ⭐⭐ 







  
  
    This can not be used with existing quick-release clamp (unless I missed something...)
  

*by D***D on Reviewed in the United States on September 8, 2019*

This is one of 2 different clamps that I bought one to install on my bike so that I could install a rear rack.  ( I bought 2 in case one was a better fit, and to have a spare).I expected that it could be clamped underneath the existing quick-release clamp, but found that it can not be used with the existing clamp.  It replaces the quick-release clamp, but does not have the quick-release feature.It has a small lip around one edge of the inner opening that rests on the top edge of the tube, and prevents it from sliding down on the tube.  Thus the original clamp can not be re-installed.  I don't recall reading about this lip in the description of the product.  I ended up installing the other one I purchased, but now if the seat post needs to be adjusted or removed, it requires using an allen key to loosen it.  Both clamps appear to share this same lip feature.So if you like the convenience of being to easily adjust your seat post with the quick-release clamp, this item is not good.

    Wrong Size!
  

*by M***H on Reviewed in the United States on November 11, 2019*

Listing title says in giant bold text "31.8mm," but I was sent a 29.8mm. I now see there is TINY text saying 29.8mm wide, in complete disagreement with what the title is selling people on!Wrong sizes don't fit on bicycles, people! Fix your listings or stop selling!
