Giant Fathom

The Giant Fathom is a hardtail mountain bike that has built a steady reputation since its introduction. It's positioned as a mid-range performer in Giant's lineup, designed for riders who want a capable trail bike without the fuss of full suspension. The Fathom combines a lightweight aluminium frame with 27.5 or 29-inch wheels, depending on the model year and variant. Giant has consistently refined the bike over the years, ensuring it remains modern and competitive.

On UK trails, the Fathom is a solid performer. Its geometry strikes a balance between comfort and agility, making it versatile enough for both leisurely rides and more technical trails. The front suspension, varying from a 100mm to 130mm travel depending on the year and model, offers sufficient cushioning for most trail conditions you'll encounter across the UK. The bike's handling is predictable, and the frame's stiffness ensures efficient power transfer, making climbs a bit less daunting.

When compared to its rivals, such as the Trek Roscoe or the Specialized Rockhopper, the Fathom stands out for its thoughtful component choices and balance between performance and price. While it may not boast the brand prestige of some competitors, it often packs more value into its price point. The Shimano and SRAM components featured across different model years ensure reliability and ease of maintenance.

The second-hand market for the Giant Fathom is quite active, thanks in part to its reputation for durability. Models from 2019 onwards tend to offer the best value, given their updated geometry and components. Look out for models with upgraded forks or groupsets, as these can offer a better riding experience without a steep increase in price. Prices generally hover between £500 for older models to around £1,200 for the more recent variants.

When buying used, pay close attention to the condition of the suspension and drivetrain. These components can wear out with heavy use and may require servicing. Additionally, check for any signs of frame damage or stress, particularly around the headtube and bottom bracket area. Some owners have reported issues with the stock tyres, so it might be worth budgeting for an upgrade if the tyres show excessive wear.

What it's like to ride

The Giant Fathom is a dependable choice for UK trails, offering a smooth and controlled ride. Its geometry is well-suited to the varied terrain found across the country, from the rolling hills of the South Downs to the more demanding tracks of the Lake District. The bike's handling is responsive, making it easy to navigate tight corners and rocky paths. Its front suspension provides adequate comfort for most trails, though hardcore mountain bikers might seek more travel for extremely rough terrain.

Who it's for

The Fathom is ideal for riders looking for a reliable and versatile mountain bike. It's suitable for those who enjoy a mix of trail riding and light cross-country adventures. This bike appeals to those who want performance without the complexity of full suspension.

Models from 2019 onwards provide the best blend of updated geometry and components. Older models can be more affordable but may lack some of the newer features and performance enhancements.
