A next-generation injection molded caster board was among products on display at the ASR Marketplace trade show, held Sept. 10-12 in San Diego.
According to its distributor, action-board sports participants can benefit from the self-propelled Shred Sled caster board, which features ABS concave decks and four large inline polyurethane wheels.
The Shred Sled is in 300 stores and adding 25-40 more stores weekly, said Eric King, president of Skyking Worldwide Sourcing LLC of Saddle River, N.J., the sled's distributor and owner of the brand name.
On any flat surface, a rider's hip movements can generate motion for a set of $120-retail, swivel-connected Shred Sled boards, which offer the freedom to combine skateboarding, surfing and snowboarding, King said.
The only limit to the tricks you can perform is your imagination, he added.
An Incheon, South Korea-based inventor whose name was not released created the product.
His firm molds the board decks on a 350-ton press using high-impact HI100 ABS from LG Chem Ltd. of Seoul, South Korea.
For the wheels, the manufacturer injection molds the inner cores with a Shore 102D-hardness-durometer PU and open-casts the outer surfaces with an 83A-hardness PU.
Each Shred Sled wheel has a diameter of 80 millimeters, compared with the 55mm diameter of a typical roller blade wheel.
King launched the Shred Sled in December 2008 as the first second-generation caster board in the market with four wheels.
First-generation caster board models with two wheels include the Wave board line from Street Surfing of Newport Beach, Calif., and the RipStik line from Razor USA LLC of Cerritos, Calif.
Nielsen Business Media Inc. of New York produced the show, which had more than 500 brands and drew about 18,000 attendees.
