I got this bike at a pawn shop near me a couple years back, and I'm assuming it's a Big box store bike, since most schwinn bikes that look like mine are from Big box stores like target, walmart, etc. I noticed on the back it says 6061 Mountain, and 6061 Aluminum is pretty tough... Right? anyways, I have already some after market components, like the forks, rear shock, handlebars/stem, wheelset, and a one by seven (11 - 34t) All that was about 900 dollars including price of bike which was 90 dollars. I know that's a lot, but did I waste my money? Is it worth putting more money into? I plan on doing some XC, trail/enduro, with small to mid sized jumps. But... any thoughts?
