I am in the market for a new bike this season and I am looking for some of your opinions. My local bike shop carry Giant and Pivot, I am looking at the Giant trance XO and the Pivot Mach 429 Carbon. Both bikes have similar component and the out the door price would be virtually the same. I do mostly trail riding in the desert and some cross country. I have ridden the pivot on a demo ride, I don't have much time on the trance. The biggest difference is the Trance has a 5" travel frame where the Pivot has 4". I am unsure which direction to go. Thank you for your opinions.
