Time Trial frame or complete bike wanted

Hi all.
After only completing approx 2 TTs a year until this year I have now got the bug after completing in all but about 3 so far this year.

I am looking to buy either a complete bike or start with a frame and build a bike from scratch. Carbon frame would be preferred unless a decent alloy frame crops up.

If you are either looking to sell or know of a TT bike/frame being sold that is suitable for me I would really appreciate hearing from you. I am 6ft 2" tall so I would guess a large frame would be right for me.

I don't anticipate having this ready before the end of this season, unless I buy a complete bike of course.

Thanks all

Bill
