Surly

2012 Troll Frameset

The Surly Troll's geometry is that of a 26" wheeled mountain bike, but it''s unlike most mountain bikes, it''s got ample clearance for 28/38/50t touring triple chainrings and room for big tires, up to 26 x 2.7". The gusseted front triangle, with its sloping toptube, provides ample standover clearance even when running high-volume big boy sized tires.

The Troll will handle just fine with a 100mm travel suspension fork if you like, or you might choose to leave the Troll''s fork in place. Like the frame, it''s made of 4130 CroMoly steel, providing a stout yet resilient ride. The fork also has rack bosses to increase load carrying capacity when the trip goes well past the end of the block.  

The Troll is so full of thought out features is would make a Swiss Army Knife jealous, like full line guides for derailleur and brake housing, fender eyelets, and disc and rim brake mounts. Both the frame and fork are equipped with mounts for front and rear racks, and the design allows the use of racks, fenders and disc brakes all at the same time.

The rear dropout area is similar to the Surly Pugsley and Karate Monkey dropouts, the Troll has horizontal, rear-load dropouts with a derailleur hanger, additionally there''s a dedicated area for anchoring a Rohloff hub OEM2 axle plate, and they''ve included threaded holes in the thick plate material for installing Surly trailer-mounting nuts.
