$91 Worth of Rubber Bands From One Recycled Inner-Tube
Posted in: Accessories and Peripherals, Today's Chili
Let’s say that each of these Plattfuss Rubber Bands, made from old bike inner-tubes, is 2mm wide. You get around 70 in a pack, which requires 140mm (5.5-inches) of OG bike tube to make them. The sizes in the pack are assorted, from different tube sizes, but to keep things simple let’s assume they come from 700c tubes.
These tubes fit a wheel with a diameter of 622 mm (forgive the international standard measurements – inches are impossible to work with at small sizes). Thus the circumference of a 700c wheel (and therefore the tube) is πD, or pi x diameter, or 1,954mm, or around 77-inches. Thus you could get 13 packs of Plattfuss Rubber Bands from a single inner-tube.
The price for a pack of the Plattfuss bands? $7. The price of 13 packs? $91. The price of a used inner-tube? Free.
