The other day I picked up a barely used OEM Mini branded bike rack to match the other one and to carry my mountain bike. It's actually a Thule rack. I got the Thule Fat Bike adapters but found that there were some slight variances between the molding on the rack vs the adapters, but I was able to get them fit. The one thing that gave me a problem was the fact that my Cannondale Cujo has such a high bottom bracket that I had to play around with the tire holders to get the bike to be held snugly. Finally, I got it set right and test drove it on the highway at 70 mph and it held fine!
