Product Info

Full suspension ain't for everyone and there are plenty of shenanigans to be had with a hardtail like the Giant Fathom 2 Complete Mountain Bike. Aside from the weight savings and simplicity of components, this ALUXX SL aluminum frame is durable and light. Spearheading your ride is a 120mm Suntour Radion for added stability while a pair of Tektro brakes modulate your speed. A proven Shimano Deore drivetrain shifts through climbs with ease, while transitions are easy thanks to the included dropper post. The Giant Fathom 2 Complete Mountain Bike awaits your favorite trails, secret singletrack, and beyond.

Product Details


ALUXX SL Aluminum ConstructionExtremely lightweight framesets featuring high-performance strength-to-weight ratios, predominantly featuring 6011 alloy. A heritage of craftsmanship combined with unmatched manufacturing capabilities gives Giant the unique ability to monitor every step of the aluminum frame-building process. Through Giant's cutting-edge materials science, proprietary forming techniques, and attention to detail, we are constantly advancing aluminum performance to create bikes that are lighter, stronger and stiffer. The difference can be felt in the ride. Every aluminum bike bearing the ALUXX Aluminum Technology label must live up to the highest standards and meet the tightest tolerances of any aluminum frame in the world.

OverDriveOverDrive provides up to 15 percent more torsional steering stiffness than straight steerer-tube designs. This translates into much more accurate steering input from a rider's hands, through the handlebar and stem, and down to the front wheel. Whether hammering uphill or carving through a corner, OverDrive transmits input directly to the front wheel for more precise handling.
