Thule 591 neatly avoids any axle standards issues. Clamp near the BB, two wheel straps, done.
How is it in terms of security? A mate of mine has a barracuda design which is very similar and he arrived to the trails one day with his bike leaning rakishly off the side of the car.
If you can look at tow bar racks. Less faff than roofracks and less chance of a bike garage interference fit issue.
I can’t really get my car in the garage anyway without a huge amount of careful manouvering. Last time I tried it was to swap the clutch out in the Subaru. Wife doesn’t wan’t anything interfering with the boot, and I’m not sure I want to be messing with lightbars and all that crap. Also, car doesn’t have a towbar so by the time I get that fitted and get a decent rack it won’t be cheap.
