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

[First Ride] Giant Reign Advanced 29

Aug 2019 · Simon Silver

To commence the launch of the new 29″ Reign series, Giant selected a world class destination of Revelstoke, British Columbia to give us an opportunity to try out the new bike.

For a quick look at our Heli drop, check out the video below, and
