    Upgrading a vintage bike?

    I bought a Trek Fast Track 420 off craigslist a while ago and been riding it. Everything was maintained pretty well but I want to ride a bike that was made 2012-2013 however I'm just a teen with no job therefore no means to pay for a $700+ entry lvl road bike. I was wondering if its possible to upgrade my Trek's current components piece by piece for example changing the wheels,fork, shifters (it has frame shifters), etc. And will that method be successful? Or should I just really save up?

    Well, how many speeds is your Trek? If it's 7 spd or less, the rear axle spacing is different and you would need to get it cold set to upgrade it. (new axle width is 130mm, old is .... uh, 126 or so)

    So can you do it? Sure. you can get a 105 group for roughly $500 and then add in new wheels. The real question is whether it's worth it to you - you would probably get more bang for your buck buying a newer bike with a newer group set.

    I just took a look right now and read "Shimano Acera X" and counted the .. i think cogs?.. and theres 7 of them... and wow I didn't know 105's costed that much just for the shifters...might as well get a new bike then

    I upgraded my vintage while I was in college not too long ago. Like you, I was wanting a bike made in this century, but didn't want to break the bank. I ended up buying low-entry level aftermarket parts for pretty much every part of the bike, except for the frame, fork, crankarm, saddle post and front derailleurs. Literally... I replaced every other part, and after $500 of 'upgrades', the bike still weights like 25 lbs. I ended up saving up for a new bike from bikesdirect altogether. aluminum bike with ultegra for $800. I'm probably going to ride this thing until I'm 30, or until I become gullible/competitive enough to buy a full carbon bike, which will probably be before 30.

    The Trek 420 is a very nice steel bicycle... if everything is in good shape there would be little reason to change anything.
