Meet Ogre, Troll’s bigger-wheel brother. Troll and Ogre offer the same ability to accommodate a wide array of drivetrains, brakes, and cargo-hauling accessories. The main difference is that Ogre runs on 29" wheels, the Troll on 26".
Built of 4130 CroMoly steel and based on the tried-and-true geometry of our venerable Karate Monkey, Ogre is designed to be a platform for exploration, commuting, trailer-pulling, on-road and off-road touring, and just riding along. Both frames feature gusseted sloping toptubes, Surly Trip Guides for running full shift and brake housing, mounts for linear-pull and disc brakes, and ample room between the stays for high-volume rubber…up to about 2.5".
Ogre comes with our suspension-corrected (80mm) fork. It features mid-blade eyelets and low-blade barrel bosses for mounting front racks. We provide canti pivots and disc brake mounts, so you can choose a system that best suits your stopping needs. And it’s specifically designed to allow the use of a fender, disc brake, and front rack at the same time. Yep, you read that right.
Like the fork, the rear end allows all-at-once rack, fender and disc compatibility. Spaced for 135mm hubs, the ‘dropouts’ are just like Troll’s…rear load horizontals with a derailleur hanger, slotted disc brake mounts, M10 x 1mm threaded holes for mounting Surly Bill & Ted trailer-connecting hardware (or B.O.B. Nutz), and a dedicated anchoring point for a Rohloff OEM2 axle plate. We designed a ton of versatility into these framesets because we want you to build up a Troll or Ogre the way it will best serve you. Framesets and complete bikes are available in sizes 16, 18, 20, 22 and supergiant 24". Tall folks, we got your back.
