Surly Ogre Frameset Large Pile of Bricks. The Ogre can get you to your job during the week then way out of town on the weekend. It’s not sluggish on pavement or gravel and can also hold its own on singletrack. Ogre has many of the same features as Troll — horizontal slotted dropouts with Gnot-Boost spacing a tweaked non-suspension corrected geometry and a beefy tire clearance — but in a 29er platform.
