Without knowing your detailed requirements or budget, I can offer the following complete bikes, all "cool" in their own manner:
- Bianchi Vento 602 (Columbus Gara), 56 cm, Shimano Exage 2x6 speed, very low mileage, as new bar a few scratches - £200
- Cilo Stratos (Columbus Cromor), 53 cm, Shimano 105 STI 2x8 speed, Mavic wheels - very good condition - £300

- Lapierre Titanium (3AL2.5V), 54 cm, Campagnolo Athena 3x8, Mavic aero wheels - great condition - £750
The dimension represents top tube length (center-to-center).
Or I can build one of the following framesets (or any of the above listed ones):
- Fuji Team Fuji (Tange, Low Profile geometry), 56 cm
- KTM Strada SL (Columbus SL), 56 cm
