2023 Giant Reign Advanced

Sep 2023

The Reign was both the easiest and the hardest bike I’ve tested so far. The easiest because it was exactly what I expected and hoped it would be: an aggressive enduro bike with excellent suspension performance. The hardest because, well, I’m just not that aggressive of a rider so I had to step out of my comfort zone and I had to be at the top of my game to get the most out of the bike.
