1991 Specialized Rockhopper Sport 20" white

Perfect do-it-all city bike .Best for 5’10”-6’6″ riders. I restored this bike as a cool city commuter all modern components: 1×7 drivetrain, 11-34T cassette for better climbing, 32T narrow/wide chainring, and fresh red components to match the original Specialized logo and stand out in the city.

This is Gannon’s bike now.
