It is very secure and easy to use on my women's style bicycle. 4 stars

Very handy item for multiple bikes on a rack. Keeps from having one bike tilted at an awkward position from the other(s). Very easy to use, just be careful as the spring tension can fool you and you can get a finger pinched. It only took one pinch and now I can set the bikes up like a pro. 4 stars

This adaptor is easy to use and worked well to keep the bike level. It also is made well because we were rear-ended with our bikes on the back of our car. The bikes were all bent up but the bar was perfectly OK. We saved the bar and had to trash the bikes. 5 stars

It's a nice to have but didn't fit my bike as the instructions suggested. To use this product I had to install it backwards from the directions since my seat post was thicker and had a shock absorber in the post. I have a Giant Sedona, medium size frame. Seems to work ok either way. 3 stars

This bar is very stout and capable of staying in place. I use it to mount two expensive Treks and feel confident the bikes will stay in place at 70mph on highway. When I picked up my new Treks, the service tech commented on the quality of the bar and asked who makes it, where I got it etc...he was impresssed of it's quality. The rubber end coatings interface well and won't harm bikes' finishes. Both my treks have different frame configurations, the bar adjusted easily. 5 stars
