The 1999 Diamond Back Venom X BMX features a full chromoly freestyle frame with oversized tubing, double-thick dropouts, and reinforced bottom bracket and head tube, paired with a matching full chromoly fork using a 1-1/8” threadless steerer, 1-1/4” blades, and reinforced dropouts. It comes fitted with 4-piece chromoly handlebars offering an 8” rise in chrome, held by an alloy four-bolt A-head stem. Braking is handled front and rear by Dia-Compe 990 U-brakes with Dia-Compe MX-99 levers, while the drivetrain uses a DB three-piece chromoly 175mm crank in chrome with a chrome alloy 44-tooth chainwheel, matched to alloy pedals. The wheelset consists of Alex chrome double-wall 48-hole rims with high-flange alloy hubs and 14mm axles, wrapped in freestyle 20x1.95” tyres. Comfort comes via a padded freestyle seat with chromoly post, while extras include an SST 1-1/8” rotor and front and rear pegs.
