Sometimes the best adventures are the toughest ones. The ones that test you. Be prepared for whatever comes your way, with a lightweight drop-bar adventure bike that can tackle paved roads, gravel or dirt.

When the pavement ends, your ride doesn’t have to. A lightweight ALUXX SLR aluminum frame, smooth-handling composite fork, and drop-bar positioning make ToughRoad SLR GX the right choice for adventuring into the unknown. The fast-rolling 700c wheels are fitted with Giant tubeless tires. These allow you to run lower tire pressure for comfort and traction, and they also reduce the risk of flat tires. The D-Fuse seatpost absorbs road vibration and shocks to help minimize fatigue on long rides. And powerful disc brakes with 160mm rotors give you added confidence and control on rough roads and in all types of weather. Thoughtful details including integrated rack mounts and the X-Defender downtube complete the package, making ToughRoad SLR GX the perfect machine for tackling imperfect roads.

  • Weight
    The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
