When we designed our Troll frame we set out to design a bike frame that would be, to its rider, a blank canvas upon which they could paint a masterpiece of versatility. The kind of frame that could be built using any kind of parts for any kind of purpose, be it riding the local backyard singletrack, getting to work, the store, or around the whole darn world.

Those familiar with the standard Troll frame know that you can pretty much put anything on it you want. Disc brakes? Yep. Linear pull or cantilever brakes? Indeed. Racks, disc brakes and fenders all at once, both front and rear? Totally. The point is that the World Troller can do everything the standard Troll frame can, plus it’ll bust in half via two S&S Machine frame couplers so you can fit it in an airline approved travel case, potentially costing you less to get your bike to whatever far-flung location you have decided to explore (make sure to check with your airline). We do advise that to properly make use of the option this frame provides, a certain level of mechanical aptitude is required. You have been warned.

Compared to 700c wheels, the 26” wheels of the World Troller have some advantages. 26” wheels are stronger than their larger counterparts, can be easier to find parts and tires for in many places around the world and pack more easily because of their smaller size. The World Troller, buy a one-way ticket to anywhere and ride your ass back home.
