It's 2012, and 26" mountain bikes are a thing of the past. Well, not entirely — your delivery guy might ride one, but when it comes to actual trail riding, the 29" wheel reigns supreme. It's with that though in mind that Trek offers the Rumblefish. a $2,600 singletrack machine that offers 120mm of travel (a touch under five inches) front and rear to absorb any rough stuff that you don't just roll over. SRAM X7 handles the shifting, Avid Elixir 3s take care of the stopping, and RockShox and Fox suspend the front and rear respectively. And for $2k less than the Rumblefish Pro you still get the same frame, so you can always upgrade later.
