My first road bike was a Giant OCR3. I kept it for a year and upgraded. It was heavy and the Sora components are the lowest in the Shimano line. The thing that took some getting used to after I upgraded to Ultegra was the Sora shifters are in a different place then all the other Shimano shifters. My hubby has stated that 105 would be your best deal if you have that extra in your budget.
