1992 Specialized Hardrock Ultra 18″ 34T upgrade

A classic do-it-all mountain bike with an upgraded modern cassette and derailleur. Best for 5’5”-5’11” riders.  Light and indestructible CroMoly steel frame in stunning violet cranberry, 21-speed Shimano 200GS drivetrain, Shimano Biopace chainrings (not round, super cool!), 26”x1.95” original all-terrain tires. I took the liberty to accentuate the bright yellow logo on the frame with yellow pedals, handlebar grips, cable housings, and saddle. Also, the original 7-speed 13-30T Shimano cassette was replaced with the new SR Suntour 11-34T. The 4 additional teeth on the cassette will make climbing a lot easier. To accommodate the larger cassette, I used the new Shimano derailleur.

This bike is now available for $600. Email me directly at bikesheaven1@gmail.com with any questions. Shipping in the continental USA is $250
