Giant Fathom 29 1 (2023)
Confident. Capable. Trail-Ready.
Built for riders who crave semi-technical singletrack, punchy climbs and flowy descents.
The 2023 Giant Fathom 29 1 offers the perfect blend of agility and stable handling.
It's paired with modern geometry, premium components and dialled trail features. So this aluminium hardtail is ready to elevate your off-road adventures.
- Premium ALUXX-SL alloy frame with progressive trail geometry.
- Giant Crest 34 RCL fork with 130mm of travel.
- Shimano Deore 1x12-speed drivetrain.
- Tubeless-ready 29" wheels with grippy Maxxis tyres.
- Dropper seatpost with remote lever.
- Powerful Shimano hydraulic disc brakes.
Precision Trail Geometry
The Fathom’s modern frame geometry delivers a balanced ride feel:
- A 75° seat tube angle positions you for efficient climbing. You can really get forward
- A 66° head angle boosts front-end stability for confident descending.
It’s geometry that keeps you comfortable on the way up and in control on the way down.
Lightweight ALUXX SL Aluminium Frame
Crafted from Giant’s premium ALUXX SL aluminium, the Fathom 29 1 is built to be light, responsive, and durable.
Material is removed from the frame where it's not required. And added where it's needed.
It shines when you’re powering up a climb or cornering through switchbacks. The Fathom reacts quickly and efficiently to rider input.
Smooth Suspension & Confident Handling
The 130mm Giant Crest 34 fork absorbs bumps, roots, and rocks. It tracks over these features smoothly; delivering grip and confidence.
The Crest 34 has larger 34mm diameter tubes for stiffness. And it uses an air spring that's adjusted to the rider's weight.
A dropper seat-post with handlebar remote allows quick saddle height adjustments. Drop the saddle low for descending and jumps. Raise it back up using the remote when you're climbing or riding on flatter trails.
High-volume 29” tubeless-ready Maxxis tyres enhance traction and smooth out rough trails. The extra grip and comfort from these tyres lets you push with confidence.
SRAM Eagle Gears
SRAM 12-speed gear deliver an enormous gear range. This helps you maintain speed on undulating trails and gives you a super easy gear for climbing. Especially climbing steeper, tricky mountain bike trails.
