Ubar - Bike Frame Adapter

It's true, some bikes fit on racks better than others, but frankly, you should choose your ride based on what works for you, not on ease of transport. So if you're scratching your head, trying to figure out how you're going to fit your new dream machine onto your hanging Alpha or Beta rack, the Kuat Ubar - Bike Frame Adapter is here to help. It attaches to your stem and your seatpost, creating an ideal horizontal mount that will make your life a whole lot easier.

The spring-loaded action keeps your bike secure, and the length is adjustable, allowing it to fit just about any bike, whether it's best described as pint-sized, or positively humongous. Plus, the rubberized hooks protect your bike from unsightly scratches. However, if you're using it on a bike with a dropper seatpost, please use extra caution, because the sliding portion of the post is more damage-prone than the anodized finish on most stems and seatposts.

The Kuat Ubar - Bike Frame Adapter is available in one size, and in one color.

  • Adapts almost any bike frame to fit Kuat Alpha or Beta racks
  • Works well for bikes with unconventional frame shapes
  • Attaches to stem and seatpost to create an ideal horizontal mount
  • Rubberized hooks keep your bike from getting scratched

Good product

  • Familiarity: I've used it several times

My wife got a new bike so we needed another adapter. I already had the other brand for my bike, but I prefer the way this one attaches to the bikes. Used it a few times with no problems.

I was expecting something a bit more sturdy when I ordered this. The description says it is spring loaded when it actually turns out to be a simple bungee and is about the width of thick yarn. I don't feel very confident in it long-term.
Also, the wider attachment that goes around your stem is very large and the whole front end of the bike sways about and the handle bars turn. Make sure you have something to secure the front wheel so that it's not moving all over the place while driving.

Super fast and easy to use. Does exactly what it says it does. Feels like it will last a long time, too.
