It's never smart to go looking for trouble, but if any should come your way, Mongoose's revolutionary new street/freestyle machine is tough enough to take it. The 1991 Mongoose Hooligan boasts the longest list of advanced features ever: 100% 4130 TIG-welded chromoly frame and fork. Removable chromoly bashguard with alloy skid plate. Chrome plated 48-spoke Araya 7X rims with sealed bearing hubs. Odyssey Pitbull brakes, a Gyro, and forged alloy two-finger levers. Forged alloy Mongoose platform pedals with chromoly spindles. Chro-moly Pro Class freestyle handlebars. 1.75-inch skinwall tires. A 26mm oversized chromoly Mongoose seat post and Velo saddle. You get the point--Bad. Just like Dennis McCoy.
