Though the Troll's geometry is that of a 26"-wheeled mountain bike, it's unlike most mountain bikes you'll find on your local bike shop floor. It has ample clearance for 28/38/50t mountain-triple chainrings and room for
26 x 2.7" tires. The gusseted front triangle, with its sloping toptube, provides generous standover clearance even when running high-volume rubber.
Build it with a 100mm suspension-corrected fork, or roll the 4130 CroMoly Troll fork. The stock fork is spec'd with canti pivots, disc mounts, low- and mid-blade rack bosses and fender eyelets. Run a rack fender and disc at the same time, no jury-rigging required.
The Troll frame features horizontal rear-loading dropouts with a derailleur hanger, disc caliper mounting slots, and rack and fender bosses. There's a dedicated area for anchoring a Rohloff hub OEM2 axle plate, and we've included threaded M10 x 1mm holes for installing Surly trailer-mounting nuts or B.O.B. Nutz. The dropout design allows the simultaneous use of a rack, fender and disc brake. We include canti pivots, too. Options, options, options. Marcia, Marcia, Marcia.
Use the Troll as a mountain bike, cruiser, commuter or touring rig. Make it your go-to utility tractor. Try out different tires and handlebars. Add some racks, build it with gears, or strip it down to a singlespeed drivetrain. Take it camping, ride it to the grocery store or session on your favorite single-track. Build it up, ride it for a while, then reinvent it.
