Where to buy 2012 SE Lager parts? Two years ago, I got hit by a car. I was fine, but my bike's fork and front tire were destroyed, so I got a new bike. Now this bike has been sitting outside for 2 years. If I wanted to replace everything but the frame, what would I search, and where would I get the parts? Assume I know nothing about bikes, but I'm very handy with tools. I also have access to a machine shop and any "normal" tools, but the only bicycle-specific tool I have is a chain tool and tire levers. I imagine it's probably not worth it (financially), but I think it's worth it to learn more about bikes and bicycle repair. Also, I welcome any other tips, suggestions, or advice.

Note: I brought the bike to a shop. They were skeptical I'd be able to salvage the frame, but they inspected it and concluded it wasn't damaged.

Edit: I'm in Boston, MA, USA
Most bicycle parts are fairly standard, and your bike doesn't look like an exception. There are several mail order stores and local shops that sell bike parts, just pick one. This site is fairly fanatical about not making recommendations, but just knowing your location could help.
