## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good quality
  

*by G***L on Reviewed in the United States on May 28, 2019*

Works as expected.  I have on the front of my bike triangle rather than under the seat, and it fits ok.  I hold my bike lock in it, and there's space for more gear if I wanted.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Compact gear bag.
  

*by D***R on Reviewed in the United States on June 2, 2019*

Works well on my 47 year old Raleigh road bike.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    These are really good.
  

*by W***N on Reviewed in the United States on June 9, 2019*

My kids have them on their bikes to hold their cable locks.  I added one to my night-ride mountain bike to hold the head-lamp  batteries. I have one on my town bike for a tube, pump, tools, and a jacket.
