Help Circle City Bicycles Create the World's Largest Tube Ball

Moab Cyclery's three foot diameter tube ball

Recently we have been creating a tube ball from discarded bicycle tubes. It is now about ten inches in diameter and surprisingly heavy. According to our scale, it weighs eighteen pounds (More than a bowling ball). Deciding that we will attempt to set a world record, a little research was done on the Internet to see where the current world record stands. According to the website RecordSetter, the current record is held by someone in Milan, Italy at 103 pounds. We had heard of another large tube ball in Las Vegas. After contacting Las Vegas Cyclery, we found out that they had one that was about two feet in diameter, which weighed over one hundred pounds. Their Moab Cyclery store has one with a diameter of three feet that is so heavy they can barely push it. I did a calculation to estimate its weight using our ten inch diameter tube ball, and came up with 840 pounds.

Please bring us your old tubes after you replace them and help us set a new world record. We have a long way to go, and we'll keep you updated on our progress. The ball is currently on display in the south window of Circle City Bicycles store.
