Founded in Mariano Comense, near Milan, Longoni is a family-owned company known worldwide for precision, craftsmanship, design, and reliability. Longoni cues are still produced entirely in Italy under the supervision of the Longoni family and are trusted by many top international players.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eThe Longoni Black Rainbow is a professional carom cue developed in collaboration with European Champion Martin Horn, combining futuristic styling, modern Longoni technology, and a construction designed for reliable, consistent performance.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eIts visual design follows clean, geometric lines with a refined minimalist character.

Introduced into Longoni products in 2019, URAL begins as a naturally light-colored, hard European wood and undergoes Longoni's specialized deep-staining process.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eUsing alternating pressurization and depressurization, an ebony-like black stain penetrates deeply into the wood. This process enhances the natural grain rather than hiding it, creating an almost completely black appearance with visible depth and character.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eEuropean hornbeam is valued for its medium-to-high density, stability, durability, and long service life, characteristics particularly well suited to billiard cue construction.

Titanium helps reduce unnecessary joint weight while maintaining excellent strength and rigidity, supporting the balance and responsiveness required in high-level carom play.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eThe key characteristics of the VP2 Titanium joint include fast and easy locking and unlocking, an ultra-firm connection for efficient energy transfer, precise butt-to-shaft alignment, smooth screw action, resistance to humidity and wear, and a more forward-balanced feel compared with Longoni wooden-joint cues.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eLongoni VP2 shafts may use brass or Ergal inserts, with the combination of joint and insert materials selected to help optimize cue balance and playing characteristics.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eThe VP2 system also provides broad compatibility across Longoni shaft technologies, allowing the Black Rainbow to be paired with S2, S20, and S30 laminated wooden shafts or the Luna Nera graphite shaft, depending on the player's preferred feel and performance characteristics.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0249\/0515\/4622\/files\/vp2-titanio-aperta.jpg?v=1780170766\" alt=\"\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eIntegrated 3-Lobite System\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eThe Black Rainbow comes with the Longoni 3-Lobite system installed, meaning the cue is prepared for use with the Longoni 3-Lobite extension system.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eThe integrated connection allows a compatible Longoni extension to be attached quickly and securely whenever additional reach is required.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003ePlease note\u003c\/span\u003e: the extension itself is not included unless specifically stated in the listing.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eDeveloped with Martin Horn\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eThe Black Rainbow was created in collaboration with Martin Horn, one of Europe's leading professional carom players.
