Surly Ogre Frameset (Champagne Supernova)

It’s not sluggish on pavement or gravel and can also hold its own on singletrack. Feel like riding from Alaska to the tip of South America? You can load everything you need on Ogre and still have plenty of space for “souvenirs”. Ogre can handle it even if you don’t think you can. Ogre believes in you so you don’t have to.

For this year, Ogre received a similar treatment as Troll did last year — horizontal slotted dropouts with Gnot-Boost spacing, a tweaked non-suspension corrected geometry, and a beefier tire clearance — but in a 29er platform. The chainstay yoke has been redesigned to be fully compatible with both 29 x 2.5” and 27.5+ tires. Now with even more of the accessory barnacles you’ve come to know and love on many of our bikes: two water bottle mounts, four sets of three-pack bosses, mid- and low-blade fork eyelets, threaded holes for racks, fenders, and trailer mounting nuts, and a Rohloff OEM2 axle plate slot. If you opt to buy an Ogre complete bike, prepare yourself to get handsy with our new Moloko bar that comes stock on it. It offers hand positions that you didn’t even know existed and the ability to mount even more accessories.

We typically try to avoid bullshit cliché terms like “Do-It-All” or “Swiss Army Knife of Bikes”, so we’ll just say that Ogre can probably handle most of the ideas that are bouncing around in your head.
