The 1998 Diamond Back Reactor JR BMX features a lightweight 7005 aluminium frame with a threaded bottom bracket and 1” head tube, paired with a chromoly fork using 1” blades and finished in chrome. It comes fitted with DB 7005 alloy handlebars offering a 5” rise, held by an alloy four-bolt stem with chromoly shaft. Braking is handled by an alloy caliper with Dia-Compe MX-101 alloy lever, while the drivetrain uses forged alloy 165mm crank arms with an alloy spider and 43-tooth alloy chainwheel, matched to DB alloy pedals with chromoly 9/16” axles. The wheelset consists of Alex double-wall alloy 32-hole rims, alloy precision sealed-bearing hubs with chromoly hollow flip-flop rear axles, and stainless spokes, wrapped in Tioga Comp III 20x1-3/8” tyres. Comfort comes via a DB one-piece seat with integrated alloy post. The bike was finished in ball-burnished with a chrome fork.
