Excellent addition - fits well with 4.8"/26" bike tires. One fatbike can fit on the roof next to the ski box when the roof rails are 127cm.
Sits on the fat bike under the tire flawlessly. Gets the tire tightened well. Works!
Easy to use and functional
Easy to install and keep the bike in place.
Quickly replaced with standard brackets.
Worth getting if you are carrying a fat bike without worrying about doing any tuning.
The 4.8-inch fat ring goes into place where the plus ring. I would have liked the adapter to fit the proride 591 version as well.
It doesn't need much to file when it can fit in my 591 rack.
Yes, those who pedal on a fatbike need the adapter more, for example in a rack (G2) that can be attached to the back door of a motorhome. Few people lift a larger bike into the roof rack of a larger bike.
