alright so i bought a 2009 specialized rockhopper last year around christmas from my lbs for 300$ SPECS; http://specialized.com/us/en/bc/SBCBkModel.jsp?arc=2009&spid=38432&menuItemId=0&gold_ses= I used the bike for a daily commuter to classes and back for around 2 months and then started riding some local trails with some friends. I fell in love with mountain biking. I believe I Ride enough to start looking for a used upgrade. Well I found a guy who works for trek and he wants to sale me a 2002 trek fuel 90 disc for 450$ SPECS; http://www.bikepedia.com/quickbike/BikeSpecs.aspx?Year=2002&Brand=Trek&Model=Fuel+90+Disc&Type=bike I know this is a better bike but what I am asking is it worth 450$ and is it that much better of a bike than my rockhopper since it is almost 10 years old? the bike is in great shape and feels like it just had a tune up. should I sale my rockhopper for 250$ and put around 400 with it and try to find a newer bike for around 650$ or should i pull the trigger on the trek? thanks for the help.
