Surly Ogre MTB Frame Kit, 27.5+/29", purple

The Ogre is designed as the ultimate steel utility vehicle. It is perfect for commuting, especially when you take the long way home and find a few drinks along the way. Whether it's snow, sleet, or humid air, this bike is an ideal commuter vehicle year-round. You can even carry so much cargo that you don’t have to go home if you don’t want to.
