Once again National Pi Day is here – my favorite holiday! Everything in the shop is 22/7 s off until St. Patricks day!

Discovered by Archimedes long,long, ago in a far away land, he was screwed out of recognition for it until recent times. Bike afficionados rediscovered it as they struggled to grasp the the meaning and differential equations needed to compare the benefits and detriments of twenty-six, twenty- nine, and 650-b wheels. This can only be understood by employing circular logic. But how much? By using PI  of course! This magical number allows you to determine the circumference of the circular logic one needs to compare, with circumspection, the concepts of contemplating cost/benefit ratios of any size wheel.

That way you won’t screw yourself at your local bike when it comes time to cinch down your commitment to circumference.
