I'm new to the MTB scene and I'm just doing some minor upgrades to an older mongoose MTB till I get a new one next year. However, I'm only 120lbs, so I figure I wouldn't need an expensive suspension fork. Maybe just a decent RockShox. On my current bike, the suspension is good, even though its not name brand(Element). So i'm assuming if you're a light weight person, you shouldn't need "the best" parts in regards to suspension?
