Or

AFAIK the components are about equal, hence the price difference is the frame; the OCR series has the same throughout from £300 to £1000, is it decent? Furthermore the tyres on the OCR are 700x25c, used to 23c, is the size much diff?

Ridden the T1500 at LBS, know its decent, and a TCR Zero which was awesome but too much money, how is the OCR Zero?

Cheers!
