    also ich denk mal konkave ist immer gut beim buttboard denk ich mal wegen dem seitenhalt.....sonst gibt es pizza an sehr schmerzhaften stellen ;)

    dicke würd ich einfach mal ausprobieren. im grunde soviel wie bei einem normalen board oder? es muss genausoviel gewicht halten. oder vll ein bissen dicker weil des gewicht sehr konzentriert ist?

    naja kann nur soviel dazu sagen
    (Ich bin auch ein Zottel)

      Im IGSA Regelbuch steht: Non-Aerodynamic Stiffeners are allowed at the Bottom. also unten kannste dranmachen.

      Mein Arschbrett is 12mm plus diverse Farb- und Lackschichten dick.

      s

      Edit: Achja, und konkav hats auch. Ist ein Weltklasse CDR-Buttboard! Ich find die Konkav auch geil, weil man so ein wenig wie in der Badewanne liegt, nur das im Moment die Badewanne wärmer ist und natürlich auch nicht soo schnell :D ....
      Es ist besser für das was man ißt gehasst, als für das, was man nicht ißt, geliebt zu werden!

          ---> Rule Book IGSA <---

          IX. STREET LUGE SPECIFICATIONS
          This class is designed to allow maximum design creativity with minimal restrictions. The only restrictions
          are made in the interest of safety or to retain the basic concept of a street luge. In the future, any further
          restrictions will be added for these reasons only. Competitors are required to ride in the supine (lying on
          back) position with their feet forward.
          A special rule clause is in effect. If an obvious safety hazard is allowed by the rules, rule changes may
          occur during the competition year. Any rule changes will be published at IGSA World of Downhill Skateboarding and
          take effect immediately.
          A. CHASSIS: The chassis must be structurally sound and not pose a safety hazard. It must not posse’s sharp
          edges, which could injure competitors. No part of the luge may present an obvious trapping, amputation or
          other hazards. Structural soundness may be demonstrated through a “Bounce Test” or other stress
          simulations, which could mimic conditions encountered while racing. No part of the luge may enclose the
          competitor’s body nor hinder their ability to brake. Nothing may protrude between the competitor’s legs. The
          Technical Inspector will be the final judge of legality.
          B. WEIGHT: The complete luge must not exceed twenty-five kilograms (25kg / 55.1 lbs). This rule will be strictly
          enforced. A 0.5kg allowance will be given for variances in the accuracy of scales.
          C. LENGTH: The minimum length shall be no less than one hundred twenty centimeters (120cm / 47.24”)
          Maximum length shall not exceed three meters (3m / 9.84’).
          D. WIDTH: The luge must not exceed sixty-one centimeters (61cm / 24”) in width.
          E. FRONT END: The front end of the luge must be padded, bumpered and/or nerfed in such a way as to
          minimize the risk of injury to a competitor who falls in front of it. Bumpers made from a soft rubber, foam,
          plastic, or other material, which will absorb energy are required. Minimal Bumper dimensions are
          seventy-seven millimeters (77mm/3”) wide, twenty-six millimeters (26mm/1”) tall and thirty-nine millimeters
          (39mm/1.5”) thick. The front end should have nerf bars or some means of deflecting another competitor,
          object or straw bales. All exposed striking surfaces must be padded. No “Toe loops” allowed. If the complete
          board does not exceed six point five kilograms (6.5kg / 14.3lbs), padding or bumpers are not required if there
          are no sharp surfaces.
          F. REAR END: The rear end of the luge must not have any unpadded surfaces, which could injure a competitor
          who runs into the luge from behind. It should be constructed so as to minimize entanglements with the front
          end of other luges. If the complete board does not exceed six point five kilograms (6.5kg / 14.3lbs), padding
          or bumpers are not required if there are no sharp surfaces.
          G. BODYWORK AND FAIRINGS: Bodywork, nose cones in front of the competitor’s feet and tail cones behind
          the competitors head and fairings are allowed. If nose cones are used, then there must be an eight
          centimeters (8cm / 3.14”) crush zone area in front of the chassis. No part of the luge may present obvious
          trapping, amputation or other hazards. All bodywork and fairings must be constructed in a manner that will
          minimize injuries in the event of collisions. Equipment should be designed so that no obvious hazards
          will be presented by the loss of bodywork and or fairings.
          H. TRUCKS: The trucks must be lean steer activated. They may be commercially available or custom built. The
          track width must be no wider than the widest part of the luge to a maximum of sixty-one centimeters (61cm /
          24”), as measured from the outside edge of the axles. The axles cannot protrude past the edge of the wheel.
          I. BEARINGS: No Restrictions
          J. WHEELS: A minimum of four (4) wheels must be in contact with the ground. Wheels can be a maximum
          diameter of one hundred thirty millimeters (130mm / 5.11").
          K. BRAKES: No mechanized braking devices are allowed.
          L. NUMBER AREA: All competitors are required to have their IGSA assigned number located on their helmet,
          bib or at the back of the board. Bibs must be worn as designed. Helmet or board numbers must be placed
          on both sides and visible in the riding position. Bib numbers must be placed on both the front and back. The
          number area and number must be of contrasting colors and highly visible from six meters (6m / 20’) away. If
          a number panel is used it must be made of flexible material and not extend past the point where the back
          bumper connects to the chassis.
          M. NUMBERS: Number digits must be a minimum of seven point six centimeters (7.6cm / 2.95”) tall each. Some
          promoters may issues a bib or bib panel with a number other then your IGSA assigned number. When race
          numbers have been issued they must be used as instructed and not tampered with cut or modified in any
          way. In this case the event number supersedes the IGSA assigned number. (For number assignment see
          section XVI. A)
          N. NUMBER USAGE: If a competitor conducts a qualifying run without the correct number displayed in the
          correct fashion, that qualifying run will be listed as Did Not Finish (DNF). A substitute run will not be allowed.
          If a competitor races without the correct number displayed in the correct fashion they will be listed as Did Not
          Finish (DNF) in the said race.
          O. BALLAST: Any weight additions shall be securely bolted to the luge chassis. Carrying of ballast on the
          competitor’s body is prohibited. Tape, tie wraps, or fasteners other than bolts are not legal for attaching
          weight. Ballast weight on all luges must be fastened with a minimum six millimeter (6mm / 0.236”) through
          bolt with nylock nuts and be cotter keyed or safety wired. Tech inspectors are charged to make thorough
          inspections of weight installation to make sure they meet the through bolt requirement.

          X. CLASSIC LUGE SPECIFICATIONS (Buttboard)
          The BASIC PREMISE is that any competitor should be able to put together a competitive board from
          skateboard shop supplies for about $300 US Dollars complete. A competitor may spend more on a board
          if they wish, however, advancements, which require a higher investment to be competitive, will be
          banned.
          Competitors are required to ride in the supine (lying on back) position with their feet forward.
          A. DECK: Must be made of laminated wood. The deck may have molded features such as a kick tail, but must
          be one piece. It may be any shape within the size limits. Nothing may be added to the deck except for the
          following:
          1. Foam padding to the top.
          2. Non-aerodynamic stiffeners to the bottom.
          3. Skateboard-type grip rails underneath.
          B. WEIGHT: The complete board must not exceed six point five kilograms (6.5kg / 14.3lbs). This rule will be
          strictly enforced. A 0.5kg allowance will be given for variances in the accuracy of scales.
          C. LENGTH: One hundred twenty-five centimeters (125cm / 49.21”) maximum.
          D. WIDTH: Three hundred five millimeters (305mm / 12”) maximum.
          E. TRUCKS: The trucks must be lean steer activated. They must be commercially available* skateboard
          trucks. Rolling axles are allowed. They must not exceed three hundred five millimeters (305mm / 12”)
          wide, as measured from the outside edge of the axles. The board must use exactly two (2) trucks. The axles
          cannot protrude past the edge of the wheel.
          *Commercially available means the product must have been distributed to at least 24 people outside the company.
          F. BEARINGS: Standard 608 type skateboard bearings only. SKF 608 Bearing Specifications: Bore 8mm
          (0.3150”), OD Race 22mm (0.8661”), Width 7mm (0.2756”)
          G. WHEELS: Only wheels originally manufactured with a maximum diameter of 70mm must be used.
          Modifications are allowed. The wheel must be commercially available*. The board must use exactly four
          (4) wheels.
          *Commercially available means the product must have been distributed to at least 24 people outside the company.
          H. RIDE HEIGHT: A minimum ride height of eight centimeters (8cm / 3.14”) is required. This is the lowest part of
          the board from the ground and includes rails, stiffeners, bolts, nuts, etc. It does not include the trucks or the
          truck mounting hardware.
          I. BRAKES: No mechanized braking devices are allowed.
          J. NUMBER AREA: All competitors are required to have their IGSA assigned Street Luge number located on
          their helmet or a bib. Bibs must be worn as designed. Helmet numbers must be placed on both sides and
          visible in the riding position. Bib numbers must be placed on both the front and back. The number area and
          number must be of contrasting colors and be highly visible from six meters (6m / 20’) away.
          K. NUMBERS: Number digits must be a minimum of seven point six centimeters (7.6cm / 2.95”) tall each. Some
          promoters may issues a bib or bib panel with a number other then your IGSA assigned number. When race
          numbers have been issued they must be used as instructed and not tampered with cut or modified in any
          way. In this case the event number supersedes the IGSA assigned number. (For number assignment see
          section XVI. A)
          L. NUMBER USAGE: If a competitor conducts a qualifying run without the correct number displayed in the
