Giant Fathom 2 2020 review

Oct 2020

The 2020 Giant Fathom 2 is a beefy, 120mm-forked hardtail with big tyres, wide 650b rims and broad bars. It’s a reliable partner for big rides on natural terrain, but the short, tall geometry and mediocre Suntour fork hold it back on technical, twisty trails.

Giant Fathom 2 review

Aug 2019 · Alex Evans

A capable, well-specced ride that requires rider confidence to eke out the most from its firm chassis

Highs
  • Great spec on paper, confident-feeling bike

Lows
  • Can be harsh on bumps, some parts aren’t as good as they look
