If anyone is looking for a secure way to carry a mountain bike have a look at the Bird Automotive one. Mine finally arrived last week at it was worth the wait. I didn‘t want to use my Saris bones one because it marks the paintwork and given a Cayman in Singapore costs >3x the price in the USA 😥 I didn’t want to take the risk. Another advantage of the rack is you can access the trunk while the bike is on the car, and when the rack is removed the receivers are almost unnoticeable. Highly recommended and easy to self-install (of course the Porsche Dealer ”cannot install anything that isn’t an approved Porsche part”…)
Custom designed bicycle racks for: Porsche Boxster, Porsche Cayman, Audi TT, Jaguar F Type, BMW Z4, Nissan 370Z and other sports cars. The industry standard. Since 2000.
