This is the Ogre, the Troll’s big wheeled brother. The 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, the Ogre is designed to be a platform for exploration, commuting, trailer-pulling, on-road and off-road touring, and just riding along. The Ogre features mounts for linear-pull and disc brakes, three bottle cage mounts (the mounts on the top of the downtube allow higher or lower cage placement depending on your needs), ample room between the stays for high-volume rubber up to 2.5", and housing guides designed to accommodate three lines which cleanly organise full length shifter and brake cable housing.
The Ogre comes with Surly's suspension-corrected (80mm) fork with threaded mounts for fenders and a rack. Both frame and fork allow the use of a fender, disc brake, and rack at the same time, an unusual feature in many modern frames. The fork also sports triple-boss bottle cage mounts, one set on each side. Each cage can be run in a high or low position, or you can run oversized Anything Cages.
The frame is spaced for 135mm hubs, with the same rear-loading horizontal dropouts as the Troll. The dropouts feature 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. Surly designed a ton of versatility into the dropouts so you can run a single speed, internally geared hub or full derailleur drivetrain, with disc or rim brakes, with or without racks and fenders, with new or older parts, whatever best serves you. Framesets and complete bikes are available in sizes small through XXL (equivalent to 24"). The complete bike parts spec is durable and sensible…just the sort of value you expect from a Surly.
If you’re like us, your bike needs will likely change by the day, week, month or year. Ride it to the office during the day, rip some local singletrack after work, use it to tote crates of freakishly large tubers next weekend, and tour that stretch of off-the-beaten-path double track next month.
With the Ogre, you can do that.
