Summary

The Giant Anthem is celebrated for its ultra-decisive steering, stable and surefooted demeanor, and playful nature, making it a standout in the cross-country category. Its Maestro suspension system is praised for consistent control and smooth comfort, though some note it can feel soft under hard power. The bike offers great value, especially in lower-tier models, with a light, racing-stiff package that doesn't compromise on fun or performance.

Pros
  • Ultra-decisive steering

  • Stable and surefooted demeanor

  • Playful nature for an XC race bike

  • Maestro suspension system for smooth comfort

  • Great value in lower-tier models

Cons
  • Maestro suspension can feel soft under hard power

  • Higher price points may be prohibitive for some

  • Some components may feel dated in certain builds

Key Quotes
This cutthroat cross-country whip took my preconceptions about XC race bikes and hacked them into a cool puddle of blood.

The great-looking Anthem Advanced SX has some features that many cross country bikes may not possess, especially at this price point.

The Giant Anthem’s ALUXX SL frame is the ultra thin-walled equivalent of alloy porcelain and Giant only lets its best welders work on the pressure formed tubes.

The Giant Anthem 27.5 3 is way more fun than expected but needs a few specification tweaks

Highs
  • Real turn of speed and precision on twisty trails, married with excellent parts

Lows
  • Tall/short sizing requires an extra long 100mm stem
