Integrated Forging With Ceramic InsideThe ProtoConcept C01 TB Irons use an innovative design, incorporating ceramic, a material with a lower specific gravity than iron, within the clubhead. This built-in ceramic stabilises head movement and improves forgiveness. The soft iron is forged into one seamless bar, delivering precise centre of gravity placement for each club. This unique integration of ceramic with forged iron provides exceptional performance, surpassing traditional materials like titanium.Centre of Gravity Design For Each Club Number By 3D CADProtoConcept uses 3D CAD technology to craft a specific centre of gravity (CG) for each club in the set. This custom design ensures the perfect balance, optimising functionality for every iron. The result is a set that maintains the precision and manoeuvrability of muscle-backs, while also offering improved head movement stability and consistent sweet spot alignment for a more controlled trajectory.Refined Based on Tour FeedbackDrawing from valuable input provided by U.S. Tour pros, ProtoConcept has fine-tuned the muscle-back design of the C01 TB irons. The updated design enhances head movement and face rotation, offering greater trajectory control and smoother mobility. The long irons promote a higher launch, while the short irons deliver superior stoppage and spin, offering a well-balanced set that meets the needs of top golfers across all aspects of their gameSpecifications Club Loft Lie Bounce FP 5i 25 ° 60.5 ° 2 ° 4.1mm 6i 28 ° 61 ° 3 ° 4.2mm 7i 32 ° 61.5 ° 4 ° 4.3mm 8i 36 ° 62 ° 5 ° 4.4mm 9i 40 ° 62.5 ° 6 ° 4.6mm PW 45 ° 63 ° 7 ° 4.9mm
