The 1999 Diamond Back Assault 24 BMX features a full chromoly frame with oversized tubing, paired with a matching full chromoly fork using a 1-1/8” threadless steerer, 1-1/4” blades, and a chrome finish. It comes fitted with cruiser handlebars offering a 6” rise in chrome, held by an alloy A-head stem (1-1/8”). Braking is handled by a Pro-Max alloy linear-pull brake with matching lever, while the drivetrain uses a DB three-piece chromoly 180mm crank in chrome with a 41-tooth alloy sprocket, matched to alloy platform pedals. The wheelset consists of alloy 24x1.75” 36-hole rims with alloy hubs, wrapped in Comp III-style 24x1.75” tyres front and rear. Comfort comes via a padded seat with alloy seatpost.
