Tiny Carbon Fiber Pyramids Used For Lighter & Stronger Bike Frames

While the Egyptians applied their pyramid building skills to making tombs, it turns out that simple shape can be just as useful for less grandiose objects, like bike frames. Delta 7 Sports has recently unveiled their Arantix Mountain Bike which relies on the IsoTruss carbon fiber and Kevlar open lattice tube design. While it might look unusual, the frame pictured above weighs just 2.75 pounds and is as strong as any other frame on the market.

The IsoTruss technology actually uses a series of small pyramid shaped structures that are all connected together to form a tube. The pyramids are made of hand woven strands of carbon fiber that are bundled together and wrapped in Kevlar. All in all, each bike frame includes 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 these frames in 2008.

A complete Arantix mountain bike starts at $11,995, but you can also order just the IsoTruss carbon composite frame for $6,995.

  1. that works out at … $23.33 per hour…. which seems a little cheap. someone’s either telling porkies or not making any money on it. 23 dollars an hour is only about £11 ph, which you can make in a no-skill office temp job in london.

  2. why would you bother… lugged steel is the coolest, then maybe Ti, then Al or alike alloys..carbon is only for sponsored riders who can afford to bingle and throw it away, or people who have no respect for the value of money and think blingy carbony thingies are cool…nope, just stupid and uncool…style man says so…go lugged steel and ride a real bike.
    At first I thought hey that’s different, but why would you bother?… now on closer look…its heavy, its unrealistically costly and a waste of human time and in fact it isn’t cool, its ugly… no…!! go classic!…hard to better the classic, and why would you want to anyway!?! only if it floats your boat and you have money to burn and no taste….. Ride on brothers and sisters ride on…!
