Key Quotes
Giant isn’t a brand that follows every trend and it often takes the truly gigantic bike manufacturer some time to implement changes, but when Giant do something, they do it right.

The Giant Reign 29 convinced us on demanding trails with its enormous composure and stability. Thanks to its active suspension, it doesn’t feel slow or cumbersome either.

the Reign was impressively predictable and more than willing to absorb any mistakes made in the rough, rooty and steep terrain

Giant Reign 29 1 review

Apr 2020 · Robin Weaver

The new Reign offers a very lively, dynamic ride but get it into the really rough stuff and it feels more like a long-travel trail bike than a mini downhill rig

Highs
  • Fox fork and shock offer plenty of useful adjustment and a really smooth, controlled feel

  • Decent geometry

Lows
  • Dropper post needs to be longer on the medium

  • Very direct feel with quite a bit of feedback so not the comfiest bike on rough trails
