Sponsors and Curators The Museum of Yo-Yo History is a labor of love, and we would not be able to stay up-to-date with exhibits without the support of our sponsors and curators. Big thanks go to One Drop Design and Duncan for supplying us with their latest models, YoYoExpert for their help and support, and to Cody Orr, TotalArtist and YoYoBrothers™ for allowing us to use their collections! If you're a manufacturer, or just a big collector and you want to help support the Museum drop me at line at chimera@yoyomuseum.com Came-Yo Mondial Exhibit #2785 Type Production Shape Modified Axle Bearing Color Silver Packaging Display Boxed Construction Multi-piece aluminum Response None Diameter 62 mm Width 27 mm Gap Adjustable - Twist Weight 53 gm Condition Mint Date 1998 Owner Rick Brough Compare Back in 1998, this innovative aluminum yo-yo featured the world's first injection lubrication system. The German yo-yo manufacturer known as Came-Yo (started by Harry Baier) introduced the "Mondial". Using an aluminum yo-yo body, Came-Yo incorporated a large rubber O-ring on the outer diameter of each halve. The Mondial featured a stepped gap-adjustment system, letting you adjust the gap width by minute degrees. A total of 50 settings were possible, each changing the gap width by 0.023 mm. The Mondial also featured the world's first injection lubrication system, letting you insert lubrication directly into the ball bearing axle without the need to disassemble the yo-yo. You simply inserted a small amount of oil into the hole in the side hub nub. A unique serial number was etched on one body halve of each production model. Came-Yo eventually closed its doors, leaving the rights to its innovative designs to Duncan, who shortly afterward released their own version of the Mondial seen here. Original retail price: $120 US.
