Calibre Two Cubed: the Go Outdoors hardtail with cult appeal

The Calibre Two Cubed sits in a rare sweet spot in the UK mountain bike scene: a no‑nonsense aluminium hardtail that rode like it cost far more than it did. Sold through Go Outdoors, it earned a loyal following by bringing genuinely progressive trail geometry and sensible component choices to riders who didn’t want boutique prices or flashy branding. For years, it was the bike people quietly recommended when friends asked how to get into ‘proper’ trail riding without emptying their bank account.

Where it came from

Calibre is Go Outdoors’ in‑house bike brand, and the Two Cubed was developed at a time when trail geometry was moving on fast — longer, slacker and more stable — but budget bikes hadn’t quite caught up. Rather than playing it safe, Calibre leaned into modern numbers early, designing a hardtail that felt confident on red‑grade trail centres and natural UK singletrack.

Being sold through a national outdoor retailer shaped the bike’s role in the market. The Two Cubed wasn’t pitched as an elite race machine or a lifestyle object; it was positioned as a practical trail tool you could walk into a store and ride away. That combination of accessibility and forward‑thinking design is a big part of why it gained cult status, especially among riders upgrading from older cross‑country bikes.

Why it works

At the heart of the Two Cubed’s appeal is geometry that prioritises confidence over twitchiness. A longer reach, slacker head angle and short stem give it stability on descents without turning climbs into a chore. It’s a hardtail that encourages riders to let the bike roll rather than constantly tip‑toe around obstacles.

Component choices were typically pragmatic rather than flashy. Suspension forks with usable travel, wide bars, decent tyre clearance and a dropper‑post‑friendly frame made it feel trail‑ready out of the box. It wasn’t about shaving grams; it was about durability and control on UK trails that are often wet, rooty and unpredictable.

• Progressive trail geometry that still climbs sensibly
• Sturdy aluminium frame built for real off‑road use
• Modern standards that allow easy upgrades
• Spec focused on control and reliability rather than bling

Who it’s for

The Two Cubed suits riders who want one bike to tackle trail centres, local woods and the odd uplift day without stepping into full‑suspension territory. It’s ideal for intermediates building skills, or lapsed riders coming back to mountain biking and discovering how much geometry has moved on. Budget‑wise, it historically sat in the affordable trail bracket, typically around £700–£1,000 new, with used examples now offering strong value if well looked after.

Variants and what to look for today

Over its life, the Two Cubed family generally followed a simple structure: an entry build with reliable basics, a mid‑level option with better fork damping and drivetrain, and a higher‑spec version aimed at riders who wanted fewer compromises. Wheel size and finishing kit evolved, but the core geometry remained the star of the show.

If you’re considering one second‑hand, condition matters more than trim level. Check the fork for smooth action and oil leaks, inspect the frame around the bottom bracket and head tube for cracks, and make sure the wheels are still true. Many owners upgraded droppers, brakes or tyres, which can be a bonus — just ensure the work was done properly.

Frequently asked questions

Is the Two Cubed suitable for beginners?

Yes, provided the rider is comfortable with a more stable, modern feel. It’s forgiving on descents, though complete novices might find it longer and slacker than older entry‑level hardtails.

How does it compare to a full‑suspension bike?

A hardtail like the Two Cubed rewards good line choice and body position. It won’t smooth out rough trails like full suspension, but it’s lighter, simpler to maintain and excellent for building skills.

Are parts easy to replace or upgrade?

Generally yes. The use of common standards means drivetrains, brakes and droppers are straightforward to swap, making it a solid platform for gradual upgrades.

The Calibre Two Cubed remains a reference point for value‑led trail hardtails in the UK. Its reputation wasn’t built on hype, but on riders discovering that good geometry and sensible spec can transform how — and where — a bike can be ridden. Even today, it stands as a reminder that affordability doesn’t have to mean compromise.
