Pearl Izumi is running a wonderful ad campaign on the best way to care for your ass. In my experience, most cyclists have asses, so the care of one’s ass is likely something that is near and dear to you if you ride a bike. Personally, I found their three simple rules for “a happy ass” to be well founded. While it is possible (especially in Beverly Hills) to purchase a new ass, it is probably best to take care of the ass you have. Asses are notoriously stubborn; if your ass is unhappy, it is unlikely that it will let you sit upon it, thereby making travel upon your ass very difficult. If you have an ass, it’s worthwhile committing these three axioms to memory.
