Calibre Bossnut

The Calibre Bossnut is a mountain bike that has carved a niche for itself within the budget-friendly segment of the full-suspension market. Launched in 2016, it quickly became a darling of the value-conscious rider, offering performance features typically found on more expensive bikes. Positioned as an entry-level full-suspension bike, it has become a go-to option for those wanting to venture beyond hardtails without breaking the bank. Over its production span, which runs until 2025, the Bossnut has seen incremental improvements, ensuring it keeps pace with the evolving demands of riders and trails.

On UK trails, the Bossnut offers a comfortable and confidence-inspiring ride. Its suspension system, while not the most sophisticated on the market, does a commendable job of absorbing bumps and roots on technical trails. This makes it particularly well-suited for beginners and those looking to hone their skills on challenging terrains. The geometry is forgiving, balancing agility with stability, which is ideal for the varied conditions of UK trails where unpredictable weather can turn a ride into a technical challenge.

When comparing the Bossnut to its rivals, it stands out primarily because of its price-to-performance ratio. Where other bikes might cut corners on components or frame quality to hit a lower price point, the Bossnut maintains a solid specification, often featuring branded components that ensure reliability and performance. It may not have the cachet of brands like Trek or Specialized, but what it lacks in brand prestige, it compensates for with practicality and value. Some competitors offer more advanced technology and lighter frames, but few can match the Bossnut's ability to offer a quality ride at such a competitive price.

On the used market, the Bossnut holds its value quite well. This is due to its strong reputation among mountain bikers and the consistent updates it has received over the years. Models from 2018 onwards, which often feature improved suspension and drivetrain components, offer the best value, balancing modern features with a more attractive price point than new models. It's worth noting that earlier models may require upgrades to match the performance of later versions, particularly in terms of fork and shock performance.

Potential buyers should be aware of a few quirks and issues. Some riders have noted that the stock suspension might require tuning or upgrading to fully realise the bike's potential, especially for heavier riders or more aggressive trails. Additionally, while the frame is solid, it's important to check for any signs of wear or damage, particularly around the suspension linkage and pivot points, as these can be areas of stress over time.

What it's like to ride

The Calibre Bossnut is well-suited for the UK's varied and often unpredictable trails. Its full-suspension setup provides a smooth ride over rocky and root-laden paths, offering a forgiving experience for newer riders while still engaging for more experienced ones. The geometry strikes a balance between playful handling and stability, making it ideal for both flowing trails and more technical descents. Though not the lightest bike in its class, its weight is manageable and doesn't detract from its overall performance.

Who it's for

The Bossnut is perfect for riders seeking an affordable entry into full-suspension mountain biking. It's particularly suited for those who frequent UK trails and need a bike that can handle varied terrain without a hefty price tag.

The 2018 to 2020 models offer a sweet spot of modern features and good pricing on the used market. Newer models from 2021 onwards come with incremental improvements but may not offer as much of a bargain.
