The maxima sable RZ from Carbon Express pushes the frontier of arrow engineering with its lightweight tri-spine architecture and precision-focused Red Zone spine configuration. By integrating a 3K carbon weave and full 360-degree spine consistency, Carbon Express has created an arrow shaft that flexes with predictability and recovers with speed, ensuring unmatched downrange consistency. The unique RedZone center section, tuned with a slightly weaker spine, actively combats dynamic spine variation, while the stiff front and rear zones reinforce structural integrity for fast, stable flight. Manufactured from 100% carbon fiber, the sable RZ excels in strength-to-weight ratio and shows over a 10% accuracy boost in field testing compared to prior generations. With up to 4X greater accuracy than single-spine shafts, minimal drop at range and a construction optimized for both durability and aerodynamics, the maxima sable RZ is engineered for bow hunters who refuse to compromise on speed or precision. Patented tri-spine/red zone tech reduces arrow oscillation by 2/3, increasing accuracy up to 4x K-360 patented outer layer uses 100% high modulus carbon weave for spine strength and durability Bulldog nock collars made from aircraft-grade aluminum protect against rear impact damage Laser match sets are spine- and weight-matched with a tolerance of +/-0.0025 inches spine and +/-1.0 grain weight for top-tier consistency Laser-tested to 1/10000 of an inch, the +/- 0.002 real straightness is held to a maximum tolerance-not an average like competitors for guaranteed consistency Launchpad precision nocks ensure consistent accuracy with integrated shaft alignment
