Giant Fathom 1 Mens Hardtail Mountain Bike 2020 in Black

Season : 2020

Brand : Giant

Code : 2011070GUNBLK

Weight : 20KG

The Giant Fathom 1 is a classic hardtail mountain bike designed for technical trails. 

The combination of a lightweight ALUXX SL aluminium frame, 120mm suspension fork, 27.5 wheels with wide rims, and cushy high-volume tyres delivers loads of traction, speed and fun on the trail. The new frame is designed with trail-friendly geometry that includes a more relaxed head angle made for a 120mm suspension fork.

The wide handlebars (780mm) and short stem give you maximum control when navigating challenging terrain. The dropper post allows you to quickly lower the saddle before confidently tackling a technical section, or to allow a better position for a fast descent.

The Giant Fathom 1 is an excellent alternative to a full suspension bike as a trail-ready machine.

Mountain Bike Sizing Guide

Mountain Bikes tend to use the T-Shirt sizing of S, M, L etc. or will have the seat tube measurement in INCHES. Why mountain bikes are inches and road bikes are CM who knows, but the part of the frame being measured is the same.

As a rule of thumb if you can identify your size as Medium on one brand, you should use that as a starting point on another brand too.

If you already own a medium mountain bike for example and are comfortable with the sizing, start there.
 

What is your height? Your suggested bicycle size
Feet/Inches Centimetres Suggested Size
4'10" - 5'2" 148cm - 158cm X-Small (14-15")
5'2" - 5'6" 158cm - 168cm Small (15.5-17")
5'6" - 5'10" 168cm - 178cm Medium (17.5-18")
5'10" - 6'1" 178cm - 185cm Large (18.5-20")
6'1" - 6'4" 185cm - 193cm X-Large (20.5-22")
6'4" - 6'6" 193cm - 198cm XX-Large (22.5"+)

Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery Dates

Estimated Delivery Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery Dates provided on product pages.
