2023 Giant Fathom 29 2 Black Diamond

Trail tuned design

Balanced geometry with a 75-degree seat tube angle puts the rider in a powerful pedalling position on climbs, while a slacker 66-degree head angle boosts confidence and control on technical descents.

Responsive handling

Lightweight ALUXX SL aluminium hardtail frame offers agile acceleration and manoeuvrability to help riders climb, corner and hammer the flats with efficiency and speed.

Smooth control

Giant Crest 34 suspension fork with 130mm of travel absorbs roots, rocks and ruts. Grippy, high-volume tires boost traction on rugged terrain. And a dropper seatpost with handlebar remote lets you adjust saddle height on the fly for confident positioning on changing terrain
