Surly's Troll Frameset is an incredible 26-inch wheeled jack of all trades. The frame and fork are built from their signature 4130 chromoly for a smooth ride and serious durability. However, what you bolt onto that sweet frameset is totally up to you. Want to run it singlespeed with road gearing, smooth tires, fenders, and cantilever brakes? Go for it. Want disc brakes, a 100mm suspension fork, and racks? Do it up. How about a Rohloff rear hub and 2.5-inch downhill rubber? Sure, that works too. Build it up, ride it for a while, then reinvent it.
