What is Coroplast?

Coroplast is the brand name for a form of corrugated plastic used for product packaging, signs and other applications.

Bicycle Applications

  • Fenders - Coroplast can be cut into strips and attached to a bicycle frame to create simple fender systems. Though not as effective as manufactured fenders, this is a cheap and easy alternative. Attachment methods include zip-ties and adhesive tape.
  • Pannier/Cargo Bags - Pannier's can be modified with Coroplast inserts to make them stiffer and prevent foot strike when pedaling. This is especially helpful for riders with large feet.

Sources of Corrugated Plastic

It is possible to find sufficient amounts of political and advertising signs in household trash. After an election you may be able to get large batches of signs donated from candidates.
