I finally sold my Chumba VF2, which was an alright bike but wasn't what I would consider awesome. Now I am in the market again. I'm looking for a do-it-all-bike since I like to both climb steep hills and bomb down the trails. I've narrowed my decision down to two bikes, the 2011 Ibis Mojo HD 140, and the 2011 Pivot Mach 5.7. I really want to build the bike under 26lbs, which shouldn't be too hard since I will be riding the new Reynolds AM wheels when they come out. What are your thoughts on either bike model? Pro's and Con's?
