If you don’t want a part of your body to get sore, then that part shouldn’t be pushing against something that doesn’t move along with it. That’s the thinking behind the vabsRider bicycle saddle, the two sides of which pivot in time with your pedaling.
That’s ridiculous. You don’t need to be a bicycle geek to care about the comfort of your commuter vehicle. I’m ten times as geeky about my rollerskates as my bicycle, despite the fact I’ve spent a hundred times as long on my bike. But I still care about comfort during those hundreds of hours a year on the bike.
