Owned and operated by GO Outdoors, the Calibre brand may not be that well known in a market filled with bigger and older bike brands, but it is one that has been stirring up some attention lately with its well-priced mountain bike options. We’ve not had a lot of experience with the Calibre brand ourselves, but that’s set to change with the all-new Bossnut V2 full suspension bike that we have in for testing and review.
With a sticker price of £1300, the Bossnut is rather tasty value for a full suspension trail bike – and especially one that’s wearing air-sprung RockShox front and rear, a Shimano Deore 2×10 drivetrain and Shimano hydraulic disc brakes.
As we all know though, nice parts don’t necessarily make a bike ride well. So lets take a closer look at some of the features on the Calibre Bossnut V2 to see what’s unique about this alloy trail bike.
“The frame of the Calibre Bossnut V2 has increased its lateral stiffness with the introduction of a one piece rocker link, which in turn has given greater clearance for a larger rear tyre – great for those UK winters. It now has wider WTB tubeless ready rims that give an overall stronger wheel, and more importantly a better tyre profile to allow more control and grip. The effective top tube of the bike has been stretched a little; this gives more room to maneuverer and allows a shorter stem which gives better steering control and confidence in steeper terrain” – From Calibre.

The Bossnut is one of two full suspension bikes from Calibre. It uses a hydroformed alloy frame, and cuts a rather pleasing shape that uses chunky and mostly straight tube profiles. The Bossnut features 130mm of front and rear travel, and rolls on 27.5in wheels. Geometry is geared towards trail riding, with a slack 66.8° head angle and a modern cockpit that features 760mm wide handlebars and a stubby 45mm long stem (60mm on the X-Large framesize).
While the frame is ready for a dropper post, Calibre does make another full suspension model that comes with one as stock, called the Beastnut. The Beastnut uses the same frame, the same 130mm of rear travel, but ups the fork travel to 140mm. Along with a 1×11 SRAM drivetrain, the Beastnut jumps up to £1499.
In terms of spec, the Calibre Bossnut V2 is brimming with value. But it’s the kicked-back frame geometry and modern cockpit setup that is most impressive for an entry-level full suspension bike. Factor in the air-adjustable fork and shock, and there’s plenty of reason to get excited by this budget boinger.
We’ll have a full review coming soon on the Calibre Bossnut V2, though for further information just head through to the GO Outdoors website.
