  • CNC machining (not stamped) combined with ultra-light computer-aided design: this precise manufacturing reduces unsprung mass and significantly improves power transfer.
  • High-strength 7075‑T6 aluminum rear sprockets: significantly lighter than steel (approximately a 33% weight reduction), they lower overall mass while optimizing power transfer without compromising durability.
  • Specially engineered tooth profile on the rear sprockets: ensures smoother chain engagement, extends component lifespan, reduces noise, and promotes more efficient power transmission.
