Here are some pics from my first off road ride on the Caffeine 29"er. You might also check out Jeff Kerkove's take on his first ever 29"er ride on this bike. I think this bike has alot of potential. Right now, all I can say is that it's a nice, smooth riding hardtail. The pics show the limits on the tire clearance that will turn off all you knobby, big, wide, and meaty freaks out there. I highly doubt that a Nevegal or Rampage will work at all in the back of this rig. Heck, I can almost get the Exi to rub the chainstay on this as it is. I'll be riding this for a couple of months and checking in here with reports and answering your questions.
