Overview
About this bike
Climb challenging trails and carve corners with confidence. Giant's Fathom 1 is an all-new hardtail that is built for adventure. This new off-road bike blends the efficient ride quality of a classic hardtail with the can-do capabilities of an all-around trail bike. It’s built around a lightweight ALUXX SL aluminum frame that’s designed specifically for 27.5 wheels. The frame features more forgiving geometry, including a 67-degree head angle designed for a 120mm suspension fork—so it’s well-suited to modern mountain bike trails. The Fathom series also offers a more rugged component selection, giving aspiring trail riders the ability to climb technical terrain with less effort and have more fun on the descents.
