Alright folks, I need your advice. I'm going to buy soon and I know very little about cyclocross bikes.

I can get this Redline Conquest



or I can get this Ibex X-ray



Redline is used, about 3 years old, and Ibex is new. the redline has 105 group with 9-speed, while the Ibex is Sora. The Ibex woudl be $100 less than the Redline.

Which is better?
