The ""Troll Frameset"" by Surly - Bikes/Frames is perfect for off-road touring. While bicycles are efficient machines, they can still break down when you're far away from help. That's where the Troll comes in. It's designed to handle the challenges of riding in remote areas.

The Troll started as a mountain bike frame, but it has evolved to become a top choice for off-road touring. The frame has been updated with more space for a larger frame bag and features Gnot-Boost spacing, allowing you to use various mountain bike hubs. The chainstay yoke is fully compatible with 26+ tyres and comes with the comfortable Jones Loop bar. The dropouts are compatible with disc brakes, fenders, a Rohloff hub, and racks all at once. The frame also includes an impressive number of braze-ons, including multiple triple bottle mounts on both the fork and down tube.

The Troll is a bike that's made for one purpose: taking you as far away from society as possible. It's time to reconnect with nature and explore the great outdoors.
