Anna V.wrote a review of Yakima RoundBar - 1 Pair on September 29, 2015
The only reason I didn't give this a 5 star rating is because I specifically used the chat function on Back Country to ask if the end caps were included with these bars. I was told that they were included and they're shown in the picture, so even though I know Yakima doesn't generally include the end caps, I though maybe I got luck with Back Country. Nope. It's not a huge deal, but I did have to track down the caps after the rail grabs and bars arrived.
The actual bars work great though!
