Description
Giant's Fathom 29 is a big wheeled trail bike designed for smooth rolling fun. The big 29" wheels give you great traction uphill and excellent stability down singletrack descents.
Built on an ALUXX SL aluminium frame, the Fathom 29 features updated geometry that produces a stable ride quality for challenging XC trails. The frame is optimised for a 130mm suspension fork for smooth control on the descents. An updated Giant WheelSystem comes with tubeless tyres already set up, making it easy to experience added efficiency and control, plus a reduced risk of flats on technical terrain.
Key Features:
ALUXX SL aluminium frameset is hand-built in-house by the world leader in aluminium engineering.
Frame geometry is designed to optimise the balance and roll-over capabilities of 29-inch wheels.
Giant Crest 34 SL RCL air sprung 130mm 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.
Set up tubeless from the factory for fewer punctures and more grip.
Please note: This model features tubeless ready wheels and tyres which offer a superior ride and less rolling resistance than traditional innertubes. This system requires tyre sealant to function correctly and this will be fitted in our workshop prior to despatch. The nature of this sealant means that the tyre may not be fully sealed until it has been ridden a short distance and therefore the bicycle may arrive with reduced pressure in the tyres. Please check the bicycle's tyres are inflated to the recommended pressure before cycling.
IMPORTANT: This bicycle is supplied without pedals.
IMPORTANT: This bicycle requires a suspension pump to set and tune its suspension correctly. This is not included as standard.

Sizing information is provided as a general guide only. This is based on the average rider riding the bicycle in the style for which it is intended. This takes no account of a rider's personal proportions, physique, flexibility and biomechanics. If your height places you on, or near, a bicycle size step then we recommend you consider both sizes. All bicycles offer a range of handlebar and saddle adjustment which will enable you to fine tune your riding position once the correct size has been established. If you are unsure on sizing, we strongly recommend you visit our store so we can assist you. Pedal On offers advice and information on sizing in good faith, the final decision and responsibility on which size to purchase is yours.
