Yes it was me who built up a bike from pieces. You can do it cheaper by going on e-bay. But you REALLY REALLY have to know what you are doing. And you REALLY REALLY have to know the new prices of everything from tires to shifter and brake cables to bar tape, to wheels handlebars... So I wouldn't recommend this approach (unless you are like me and been working and building bikes for like last 20-30 years) and you've built up bikes before. You also need some special tools.
My k2 mod6 uses SRAM FORCE groupo. Cost of the completed bike is around $1700. k2 frame cost me $200.00 so you can see where the money is going. not the frame.
I saw a k2 mod6 wih lesser groupo with steep discount (50% off) for $1599.
My TT bike Specialized S-works Transition Pro cost me about $2200. also with SRAM FORCE groupo. again the frame cost me less than 1/3 of the total cost. MSRP from Specialized was $4,400 or there abouts.
Buying the groupo at retail is very expensive. Getting the groupo on a completed bike will cost you half as much. but then you have to deal with the frame, seat, handlbar, wheels etc.
Buy a complete bike is much better way for you. Sightly used with less than 1000 miles, no crash, not being ridden in the rain bike is what you should look for on e-bay. Oh and never raced or never used in tri-athalons.
