Product Details

Giant Fathom 2 2019 Trail MTB

The Giant Fathom 2 is a trail-ready hardtail mountain bike. It features Tektro HDM 275 hydraulic disc brakes, Shimano Deore 1x10 gearing and, most remarkably, it rolls on tubeless tyres!

Key Features

  • Maxxis Ardent Race 27.5x2.4" Tubeless Tyres
  • Fitted with tubeless tyres, previously reserved for Giant's Pro-quality £2,000-plus bicycles
  • Giant so believe in the benefits of tubeless tyres (improved cushioning, traction and puncture resistance) they are now fitting them as standard on more and more of their bikes from around £1,000 - More on tubeless tyres
  • The frame is built with the lightest and most compliant ALUXX SLR-Grade MTB alloy tubing that Giant manufacture
  • That's some claim when you consider Giant are the world's largest manufacturer of aluminium bicycle tubing
  • Proper trail geometry
  • The slack 67˚ head tube angle improves stability for confident downhilling
  • The steep-ish 73.5˚ seat tube angle makes it easier to ride out the saddle and boost yourself up climbs
  • The Shimano Deore 1x10 drivetrain with Shadow Plus rear mech offers an exceptional range of gearing for all terrain via its 30T chainset and 11-42 cassette
  • Tektro HDM 275 hydraulic disc brakes bring Shimano reliability to the benefits of good quality hydraulic disc brakes


ALUXX SL aluminum frameset is hand-built in-house by the world leader in aluminium engineering.


Frame geometry is designed to optimize the confident, stable handling of 27.5+ tyres, and is ideal for rugged, adventurous terrain.


More relaxed frame geometry (compared to XC) and control-focused components deliver added control for trail riding conditions.
