LEVI'S OGRE
This is the most versatile bike I've owned. In two years, it's been five different bicycles. As a commuter, it's seen both egg-frying pavement and zero-visibility ice storms. As a mountain bike, it's been both a trail slaying hardtail and a ripping rigid machete. I've never ridden a mountain bike that so precisely does exactly what I want it to do. Like an ogre, it's basically unstoppable.
The Ogre frame is special because it has the same trail geometry as Surly's Karate Monkey, but it's also designed to run racks, fenders, and disc brakes all at the same time. You can even pull a trailer while you're at it, too. It is a bike that has seemingly endless specialties, off-road touring, winter commuting, and trail riding to name a few.
There are three places to mount a Salsa Anything Cage--on either side of the fork and on the down tube. The rear dropout have mounts for a Surly Bill or Ted trailer, as well as a Rohloff torque arm slot, which means you can run an internally-geared Rohloff hub and make your drivetrain impervious to the elements.
All of that said, I like my Ogre best the way it's set up currently.
The carbon fork lightened up the front end a little, and livened up the steering a lot. The Velocity P35 rims are not only awesomely white, but a whopping 35mm wide, which means that those 2.4 Maxxis Ardent tires look absolutely enormous, and I can run a very low pressure without damaging a rim. This bike has been all over the front range, Fruita, Durango, and Gunnison. It's ridden the Bailey Hundo and the Steamboat Stinger. In all of that time, I've never wished it were anything other that what it was. Oh, and that bell is a pretty crucial component, too.
