Carbon fiber pyramids for lighter & stronger frames

While the Egyptians applied their pyramid building skills to makingtombs, it turns out that simple shape can be just as useful for lessgrandiose objects, like bike frames. Delta 7 Sports has recentlyunveiled their Arantix Mountain Bike which relies on the IsoTrusscarbon fiber and Kevlar open lattice tube design. While it might lookunusual, the frame pictured above weighs just 2.75 pounds and is asstrong as any other frame on the market.

The IsoTruss technology actually uses a series of small pyramidshaped structures that are all connected together to form a tube. Thepyramids are made of hand woven strands of carbon fiber that arebundled together and wrapped in Kevlar. All in all, each bike frameincludes 1,672 feet of carbon fiber and takes about 300 hours to build.As a result Delta 7 Sports only plans to produce about 200 of theseframes in 2008.
