How cheap do you reckon one could build a road rat or kinesis frame up for?

With gears

flat bars or drops??

i built my CX bike up from new for £450

[EDIT] £650 sorry. [EDIT]

drops..

what would the wheels and drive train likely cost?

you can pick up a set of wheels for £120ish
Shimano
105 group set

that lot there adds up to £460!!

plus a frame, forks, headset,seat post, saddle, seat clamp and pedals.

forgot bars, stem and bartape

Any other suggestions for the groupset/deals?

I think ive got an old mtb saddle that would do for now and definitely pedals lying about

mine cost about £600

new frame/fork, crank, bars and brakes (Fleabay), seat, rear mech and headset (STW)

2nd hand wheels, tyres, stem, grips, shifter, pedals and Seat post.

I must thank STW classifieds and fleabay.
