Giant Fathom 2 27.5" MTB Bike 2017

Product Code: 146642


This new off-road bike blends the efficient ride quality of a classic hardtail with the can-do capabilities of an all-around trail bike. It’s built around a lightweight ALUXX SL aluminium frame that’s designed specifically for 27.5 wheels. The frame features more forgiving geometry, including a 67-degree head angle designed for a 120mm suspension fork - so it’s well-suited to modern mountain bike trails. The Fathom series also offers a more rugged component selection, giving aspiring trail riders the ability to climb technical terrain with less effort and have more fun on the descents.

  • Frame: ALUXX SL-Grade Aluminium, Tapered Headtube, Semi-Internal Cable Routing
  • Fork: Suntour Raidon XC RL-R, 120mm Travel, Tapered Steerer Tube, 15x100 axle
  • Drivetrain: Shimano Alivio and Deore18 speed
  • Brakes: Shimano M315 hydraulic disc brakes, 180/160mm rotors
  • Wheels: Giant GX03V rims with Giant Tracker hubs

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 Giant bikes are designed for best-in-class weight and ride quality.
