Hey Guys I am brand new here and I got a question.

In 2002 I got a Univega ds700 I know it isn't a great bike but I dont want to buy a new one. I need to replace the rear shock and I don't know much about shocks. I ride in the city jumping cubs and riding fairly ruff. I am 210lbs and need a decent quality shock for a decent price. Gas, oil, air, I dont know. What do you guys suggeest?

If you need more info just let me know.
