The Troll is a versatile dirt road touring bicycle with all the bells and whistles necessary for an extended tour.
Trolling the Limits of Exploration
Troll is the expedition touring bike that started us down the winding, mostly unpaved path of dirt road touring. It’s fully-equipped to get you out there — way out there — for very long periods of time and its highly-versatile dropout design allows you to do so in a variety of ways. Singlespeed? Rohloff? Pulling a trailer? Yep. All of that and so much more.
Chances are, Troll can handle most of the ideas that are bouncing around your noggin. Feel like riding from Alaska to the tip of South America? You can load everything you need on Troll and still have plenty of space for “souvenirs.” Troll can handle it even if you don’t think you can.
“Troll believes in you, so you don’t have to."
