Sporting Shimano Altus brakes with Shimano Tourney TY-30 levers and a Grip Shift SRT-300i shift lever, the 1996 Rockhopper belonged the the Shimano AceraX component group at Specialized. Its front derailleur, or gear-changing mechanism, was a Shimano AceraX top-swing bottom-puller, and its rear derailleur was a Shimano STX. The crankset was a Specialized Son of Strongarm with 20/32/42 teeth, and the pedals were made of HTI steel and resin. A Shimano BB-LP26 bottom bracket with a 107 mm spindle and a 73 mm shell width accompanied the seven-speed, 11- to 28-teeth rear cogs and Shimano CN-UG50 1/2 by 3/32-inch chain.
The Rockhopper's 30.4 mm diameter seatpost, made of micro-adjustable alloy, supported a Specialized Comfort Plus Sport saddle. The alloy handlebars were set on a chromoly stem, and the bike had a 1 1/8-inch sealed headset, which is the mechanism that connects the fork to the frame and allows you to turn the bike.
