In 1991, cyclist Graham Bergh got a flat tire and used the flat inner tube to hang his stereo speakers. Intrigued with the notion of reviving discarded bicycle parts, he founded a company based on just that: creating functional products from recycled bike products.

Bent Crank Arms

As long as the distance from crank axle to pedal is fixed, there is no pedaling advantage in using bent crank arms

Cotterless, Three-Piece Chainrings

Three-piece cranks, or Cotterless cranks, have two crank arms pressed and bolted to the crank axle, hence three pieces. Chainrings are usually interchangeable in this format, offering more options for touring and racing cyclists. Interchangeable rings are bolted onto the crank arm's spider arms, like a spider or tentacles of a star fish, with chainring bolts and, if necessary, chainring bolt spacers. There are three-, four-, five-, and six-spider arms, with many sizes of chainring bolt circle diameter (bcd).
