XRay Graphite 2-Speed Gear 45T (2nd)

The XRAY Graphite 2-Speed Gear 45T (2nd), part XR345645, is a precision‑moulded module 1 spur gear engineered for high performance and durability. Formed from XRAY’s lightweight, extra‑strong graphite composite, it balances hardness, toughness and flexibility to deliver long life, minimal wear and reduced risk of tooth stripping or breakage, even under extreme racing loads.

The gear is strategically lightened to cut rotating mass, supporting increased drivetrain efficiency. A specially designed injection process ensures even material flow for ultra‑true, wobble‑free running. Each gear is clearly stamped with the tooth count for quick identification, and the range is available in popular sizes to help dial in the ideal gear ratio for any track.
