The following video and images represents the ASTM testing of the ROUNDTAIL STEEL bike frame completed at MIcroBac Labs Hauser Division 4750 Nautilus Court South, Unit A Boulder, CO 80301. The F.E.A. testing was completed by Independent Engineer; Windsor ON. Canada Based Tom Stein. The vertical testing was performed in accordance with the test requirements embodied within the Draft ASTM Standard Specification for Condition 1 Bicycle Frames as follows: Horizontal Loading Durability Fatigue Test: "The Roundtail frame was tested a minimum 100,000 cycles with a cyclic load of 600N tensile and 600N compressive". And tested in horizontal fatigue configuration with a test fork of 367 mm (14.4 in.) in length. A cycle rate of 2 Hz was used. The testing was performed using force control. Vertical Loading Durability Fatigue Test: "The ROUNDTAIL frame was tested a minimum 50,000 cycles with a cyclic load of 1200N to 120N load in the compressive direction". Impact Strength Test: "The ROUNDTAIL frame was tested with a drop height of 180 mm, and the permanent set of the frame and fork was less than 40 mm." ASTM F2711 specified the impact mass to be 22.5 Kg. (Video shows 3 instances of IMPACT for dramatizing the frames reaction to the impact, only ONE instance was required for the actual TEST of the vertical impact.
