Hydroformed 6061 aluminium, 130mm (5.1in) travel RockShox Sektor Silver RL, 130mm (5.1in) travel Because the wheelbase isn’t overly long, you don’t have to ‘bus driver’ the wide way round tight turns and even novice riders synced with the Calibre straight away. While it’s not as stretched out and stable at the front end as Voodoo’s excellent Canzo – a rival for its budget full-sus crown – as soon as you settle in behind the wide bar it feels well balanced and confident.

The amazing thing about the Bossnut is that nothing needs upgrading to complete a totally sorted package.

The switchable clutch mechanism on the Shadow Plus rear derailleur increases spring strength to stop chain slap and makes a future switch to a single chainring up front simple. The shifters use integrated I-Spec mounts for a clean cockpit and the brakes offer decent feel and control.

The WTB i23 rims and tyres are tubeless ready if you add tape and valves, and the combination of Vigilante front and Bee Line rear tyres gives a great balance of traction and speed.Ī full set of Shimano Deore stop and go gear brings a ton of small but significant features as well as slick 20-speed shifting and proven durability. The Sektor fork they sit on top of is the same slightly heavy, steel-legged Silver model found on such peers as Boardman’s FS Team, but a 15mm axle gives accurate wheel placement and line-holding in hairy situations. The confidently slack-steering angles connect with a properly wide bar for maximum control The confidently slack-steering angles of the bossnut connect with a properly wide bar for maximum control: The 760mm Ritchey bar gives loads of trail-taming leverage and the matching stem gives a good balance of responsive but not twitchy steering manners for a range of riders and riding.

Even if you go through the spec with a fine-tooth comb it’s a genuinely weak-link free selection that we’d be content with on a bike at twice the price. Where Calibre really starts to score with the Bossnut is componentry. Sizing options are limited to small, medium and large though, and the reach is adequate rather than stretched so you may want to size up. The geometry is bang-on for technical trail riding too, with a slacker than listed 66.7-degree head angle but relatively steep 73.5-degree seat angle and standard issue 340mm BB height proving Calibre hasn’t just stuck a long fork in an old, out of date frame. The Monarch rear shock uses a relatively firm compression damping setting to keep suspension bounce to a minimum All we had to do was run the Sektor fork at the higher end of the recommended pressures printed on the back of the fork lowers, and run the rebound adjusters fully open on the fork and shock.The monarch rear shock uses a relatively firm compression damping setting to keep suspension bounce to a minimum: With RockShox taking care of suspension duties, it was relatively easy to get a balanced set-up on the Bossnut. This is great news for anyone either side of 5ft 10in, as taller and shorter riders can also benefit from the Bossnut’s killer ride quality. Unlike the Boardman, however, the dimensions are a little more generous on the size Medium Bossnut, so we didn’t automatically feel the need to go for the biggest frame size. Just like Boardman, Calibre only offers the Bossnut in three frame sizes.
