    The Revolutionary Arantix IsoTruss Mountain Bike Frame

    4
    By Jason Mitchell on November 20, 2007 Mountain Biking, New Gear, News

    This bike looks crazy! Weighing in at a mere 2.7 lbs for the frame using IsoTruss tubes. This is pretty darn cool technology, but isn’t coming cheap. The frameset (only 200 will be produced in 2008) will cost $6995. If you’ve got the coin, check this bike out! Simply amazing!
    Delta 7 Sports Arantix IsoTruss Carbon Fiber Mountain Bike

    Here’s the word from Delta 7 Sports:

    PAYSON, Utah – November 14, 2007 – Delta 7 Sports, LLC today unveiled its Arantix™ Mountain Bike, the first bicycle to feature the patented IsoTruss® carbon fiber and Kevlar spider web-like open lattice tube design.

    With the IsoTruss technology and design, Delta 7 Sports has created one of the strongest and lightest mountain bikes in the world, with a “hard-tail” (no shock absorbers) frame that weighs approximately 2.7 pounds and sports the unique and extremely strong see-through IsoTruss design.

    Advanced Composite Solutions, LLC (parent company of Delta 7 Sports), has been granted an exclusive, worldwide license by Brigham Young University to develop, produce and market products utilizing the IsoTruss technology and design. The Arantix is the first ACS product to utilize IsoTruss technology.

    “It was imperative that we prove we could design and produce a reasonably priced marketable product using the IsoTruss technology and design, and that’s what we’ve done with the Arantix Mountain Bike,” said Jon Adams, president and CEO of Advanced Composite Solutions. “Not only is it one of the coolest and most unique looking bikes you’ll ever see, but the IsoTruss structure of the tubing gives the Arantix frame an unparalleled strength to weight ratio. For that cycling enthusiast or weekend rider who wants the most unique, coolest-looking mountain bike on the planet – whether that’s a complete bike or a frame that they can build out themselves – this is the right bike.”

    Arantix Mountain Bike Information and Specifications

    Each Arantix Mountain Bike frame takes approximately 300 hours to build, as Delta 7 Sports workers weave single carbon fiber strands in a precise manner and order to create the open lattice IsoTruss structure of each frame tube. Each bundle of carbon fiber strands is then constrained within a helical wrapping of Kevlar string designed to tightly bind the carbon fibers together before the tubes are baked at 255 degrees Fahrenheit for four hours. The ends of the baked tubes are then machined to specific measurements and diameters before being joined with molded carbon fiber lugs into a completed frame.

    “In total, each completed Arantix frame is built with 1,672 linear feet of carbon fiber,” said Tyler Evans, program manager of Delta 7 Sports. “That’s longer than five and a half football fields, or by comparison, a single strand that long would reach to the top of the tallest building in the world, the Taipei 101 in Taiwan.”

    Delta 7 Sports is now taking orders for its custom, hand-built Arantix Mountain Bike, at prices starting at $11,995 (USD) in small, medium and large sizes. The company only plans to build/deliver 200 bikes in 2008.

    Each complete Arantix Mountain Bike includes:

    • An Arantix IsoTruss carbon composite frame
    • Fox F100 RLC front suspension
    • Complete Shimano XTR drivetrain ( i.e. shifters, brakes, crankset, cassette, chain, etc.)
    • Shimano XTR wheels with Kenda Karma DTC tires
    • Crank Brothers Four Ti Egg Beaters pedals
    • RaceFace Next SL carbon fiber handlebar with two LizardSkins Lock-On grips
    • L.H. Thomson Masterpiece handlebar stem and seatpost
    • Chris King NoThreadSet headset
    • Selle Italiá Kit Carbonio saddle
    • Complete LizardSkins Arantix frame skinset.

    Individuals interested in custom-building their own mountain bike, can also order an Arantix Mountain Bike frame by itself from Delta 7 Sports for $6,995 (USD).

    IsoTruss Technology and Design Overview

    IsoTruss was developed at BYU under the direction of Civil Engineering Professor David W. Jensen (Director of the Center for Advanced Structural Composites).

    IsoTruss open lattice structures are made up of three-dimensional (3-D) pyramid-shaped trusses formed by combining two-dimensional (2-D) trusses, such as the kind commonly used in architectural design. The pyramid-like structure of an IsoTruss lattice utilizes the well-known geometry of a triangle with two equal sides (an Isosceles Triangle) to create a form with a superior weight-to-strength ratio. Hence, the name IsoTruss comes from the “iso” in isosceles, while “truss” comes from the architectural design known as trusses.

    The fusion of 2-D trusses into the 3-D pyramid-shaped forms found within an IsoTruss structure enables Delta 7 Sports to build bicycle frames that bend less, twist less (torsion) and flex less (axial stiffness) than metal bike frames of comparable weight.

      So… do they have a partnerhip with LendingTree.com? 🙂

      Seriously though, looks like a sweet concept. Can’t wait to see the road bike.

      I was unable to ride this bike at the Interbike Outdoor Demo, but I saw something that was a little concerning with this bike. I watched a rather dirty but otherwise OK rider walking his Arantix down the trail with a broken head tube. He had the bike over his shoulder and the fork and attached head tube was completely dangling.

      I’m by no means saying this bike is going to fail, but it is new technology and it may take a little longer to dial everything in.

      ALSO… I don’t know what this guy was doing on the bike, but he was in full spandex, so I’m guessing he wasn’t dropping it off the roof of the bathroom.
