Spec from Diamondback's own BMX site (diamondbackbmx.com) model page (web.archive.org capture 2008-06); model year from Diamondback BMX's own image code on the page (09_db-bmx_620x426_reactorjr.jpg). The model year evidence conflicts: the page's own menu labels it "Reactor Junior (2008)", and Diamondback BMX later filed the same page (same specification) in its 2008-race archive folder (capture 2009-04), while the product image is coded 09_db-bmx; 2009 follows the image code only. Frame: 7005 heat treated aluminum w/ 3D forged dropouts; headset FSA 1" threadless; bottom bracket Euro w/ sealed bearings, tapered square axle; chain KMC 1/2 x 3/32; sprocket 40t alloy; pedals Alloy body / cage; grips DB Race; extras Owner's manual, chain tensioners.
