⚙️ TECHNICAL ENGINEERING AND DESIGN ANALYSIS:

1. 🏗️ MATERIALS SCIENCE AND DURABILITY ENGINEERING:

• Material Composition: High-density, glass fiber reinforced nylon 6/6 (PA66-GF).

  • Mechanical Properties:

    Parameter	Value	Benefits
    Tensile Strength	80-100 MPa	It withstands torsional and bending forces during lifting.
    Impact Resistance (Izod, bent)	45 J/m	Resistance to fracture under sudden loads.
    Modulus of Bending	4.5 GPa	The rigid construction prevents the tire from flexing when lifted.

  • Advantages: Compared to metal It does not scratch rims or tires , is very lightweight, does not cause corrosion, and does not conduct electricity.

2. 📐 ERGO-BIOMECHANICAL and GEOMETRIC OPTIMIZATION:

• Dimensions (for a single lever): ~114mm length, ~15mm width, ~44.5mm depth.

• Critical Design Features:

  1. Narrow and Thick Tip:

     • Tip Thickness: 2.5mm - the gap between the tire edge and the rim. narrow space compressible.

     • Tip Width: 8mm - provides sufficient contact surface to the tire without damaging the tire bead wire.

  2. Hook Profile Design:

     • Hook Depth: 6mm - securely grips the rim; the lever doesn't detach from the rim even when it comes out of the tire.

     • Hook Angle: 25° - provides the optimum lifting angle.

  3. Ergonomic Grip Handle:

     • Width: 25mm (maximum) - a comfortable grip surface for the fingers.

     • Surface Texture: Slightly textured, non-slip surface.

3. 🛠️ COMPATIBILITY AND PERFORMANCE CAPACITY:

• Compatible Systems:

  • All Clincher Tires: 20" - 29" inclusive.

  • Tubeless Systems: The narrow tip is suitable for lifting tightly fitting tubeless tire edges without compromising their seal.

  • Rim Widths: For tires with an inner width of 13mm to 30mm+ (2 or 3 levers can be used together on high-volume tires).

• Lifting Capacity: A single crowbar, ≥150 N (≈15 kg-force) The tire edge can withstand the lifting force.

4. ⚖️ SET DYNAMICS AND USAGE EFFICIENCY:

• The Logic of a Set of 3: It is based on professional repair procedures.

  1. The First Crowbar: It initiates and stabilizes tire-rim separation.

  2. Second Lever: It perpetuates the division.

  3. Third Lever: It speeds up the process or is used as a freehand when one of the first two is compromised.

• Weight and Portability: 37g (total set). This weighs less than one standard metal crowbar.

🛠️ PROFESSIONAL USAGE TECHNIQUE AND PROCEDURE RECOMMENDATIONS:

1. Correct Position: The tire, opposite the valve Start lifting from that point.

2. Wheel Protection: The crowbar hook, behind the wheel rim (attach it to the inner surface of the rim tape/rim), NOT on the sidewall of the rim.

3. Gradual Progression: When the first lever gets stuck, from it 5-7 cm Continue the process with the second lever from a later point. "Walk" along the lever.

4. In Tubeless Systems: Hooked end carefully Slide it under the tire edge. Tire edge from the inner edge of the rim (hook) Lift vertically upwards; do not force it sideways.
