Rock Shox Recon RL forks are now fitted, still with 130mm travel and 15mm bolt through, but they are stiffer than the previous forks and give greater control in changes of direction and tracking your lines.Ī 1x11 SRAM NX drive chain provides simplicity for the rider, yet still gives a huge range of gear ratios to clear any climb. The frame stays with its superb geometry but now features both internal and external stealth dropper post routing, letting you choose whichever suits your style. Having listened to the many magazine reviews, team riders, and customers, Calibre have updated their Bossnut V2 with a view to making the best even better. While Rob’s a mountain biker at heart and never happier than when he’s sliding down a Welsh hillside, he’s more than happy to put the miles in on the road or gravel bike, too.Evolution can take a long time, thankfully the Calibre team are quick to act - let the fun begin! Lots of small changes have come together to make one big change and produce a new class killer, the Calibre Bossnut Evo. A degree in sports technology and decades of riding experience all help to give Rob a thorough understanding of what’s needed to create a great bike or product. After many years competing on the UK national circuit (including a year attempting to race UCI DH World Cups), Rob realised his know-how and passion for bike setup, tech and writing clearly outweighed his racing ability. He cut his teeth racing cross-country mountain bikes in the early 90s before finding his feet in downhill. Rob’s expansive knowledge of bikes comes courtesy of his passion for racing. In 2010 he joined the team full-time and has been keeping a close eye on all things test-related ever since. Rob first graced the pages of MBUK back in 2001 when working as a freelance writer and went on to start testing bikes for the title in 2007. Rob manages all of the testing here at BikeRadar and across our magazines, Mountain Biking UK and Cycling Plus. Rob Weaver is BikeRadar's technical editor-in-chief. 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.
