When I got the CM, or rather, when I was planning for it, I made the decision to use a roof rack system this time instead of my tried and true rear hitch rack method as per the previous cars. Truth be told, I'll always prefer the rear hitch in actual application: easy to access, low profile, less drag, and very adaptable via multiple rack types. However, I more and more often found myself in situations where I was stranding a bike. My lovely wife would pick me up and not have the rear rack on the MINI, and so I'd be stuck doing the bike shuffle until I got into the office with the rack on. Similarly, I was stuck on a long ride one time and my lovely wife couldn't come get me because the rear rack was too heavy for her to install on the car. So, the one advantage to the roof rack system is the fact that it's always on the car (assuming you don't, you know, take it off)
There were a lot of little machinations along the way getting to my final setup. I looked at different roof rails, different bike trays, etc and finally decided on the OEM rails and trays shown. The trays are a design similar to Thule and Yakima's versions that have a downtube clamp, with front and rear wheel straps. They are odd that they sweep UP at the front. The rails are really very similar than the Thule aeros, with some slight depth differences.
I set them up, but I never had the opportunity to actually use the system until yesterday. We had been yacking offline, Lung and I, about a really cool stool designed to unfold and hang from the vehicle's wheels, but I never bought it, keeping costs down. But I wondered about access issues and had contingencies. Sure, lifting a light road bike or fixie up to the roof of a car isn't a big deal but add in the project bikes with heavy crap on them, the 29ers with their awkward geometries, and my shoulder SLAP tear injury, and you could have a problem.
Anyway, what I discovered was that the rear sweep of the door jamb is severe, since they pushed the seats over the rear axle, and the door has to glide over the top of the wheel well. This means you can stand in the footwell and then have a foot at the door sweep to the left, and easily have the balance/support necessary to carefully lift the bike up, and back down same, without needing a stool. Granted any regular MINI wouldn't need a stool either, but the CM is 8" taller, around the same height as a larger sedan or small crossover. The bike being carried this round was my grocery getter/baby hauler fixie, Ye Black Death, which has a lot of front end weight thanks to the Gomoh rack. NO PROBLEM.
The downtube clamp has a very large max diameter, more than some of the other brands, which was partly why I was sold on the OEM. 29er, fat MASH aero section, whatever, it can handle it.
Good system! Still doing experiments on wind drag/noise/mileage with the racks and fairing and so on, but that's ongoing._________________
