Product Description


Giant Fathom 1 29ER 2018

This top of the Giant Fathom 29er range trail hardtail mountain bike comes appropriately equipped with a Shimano SLX 1x11-speed drivetrain.

  • The wide range 1x11 Shimano SLX drivetrain with 11-46 cassette should convince you that you only need one gear shifter
  • What's so good about a one-by drivetrain? - see blog
  • Maxxis Icon 29x2.2 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 2018 bikes from around £1,000 - more on tubeless tyres
  • The frame is built with Giant's lighter weight ALUXX SL alloy tubing
  • Proper 29er trail geometry
  • The slack 69˚ 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
  • Shimano M-365 hydraulic disc brakes bring Shimano reliability to the benefits of good quality hydraulic disc brakes

Here's how Giant describe the Fathom 1 29ER 2018


With smooth-rolling 29er wheels and a lightweight hardtail frame, Fathom 29 keeps you balanced and in control on all types of XC terrain. Built on an ALUXX SL-grade aluminum frame, it features relaxed geometry that, when paired with its large-diameter wheels, produces a stable ride quality that's ideal for challenging XC trails. Efficiency on the climbs, and total control on the descents. You get both with Fathom 29. Tubeless ready.

  • SR Suntour Axon LO-RC 100mm-travel fork with 15mm thru-axle
  • Shimano SLX 1x11-speed drivetrain
  • Shimano M365 hydraulic disc brakes
