The bike is actually an evolution of the Beastnut, a short run of limited-edition higher-spec versions of the Bossnut that sold out very quickly when they were released in January of last year. The Triple B is the permanent replacement of that crowd favorite.

Calibre Triple B highlights
Compared to the V2 version of the Bossnut, which costs £999 (£1,300 without the discount card), you can buy the Triple B for £400 more at £1,399 (£1,600 without the discount card), with some substantial upgrades.
Starting from the back, the rear triangle gains a thru-axle, and up front, a higher spec 140mm travel RockShox Reba RL fork replaces the 130mm Sektor used on the Bossnut.
The 2x Deore groupset has been swapped out in favour of a 1x11 SRAM NX. A Tranz-X dropper post and a set of SRAM Guide brakes have also been fitted.
While Go Outdoors is a UK-based retailer, it’s worth bearing in mind that the outdoor mega-retailer offers world wide shipping.
It’s no secret that we’re big fans of the Calibre Bossnut — Go Outdoors has done a stellar job putting together a properly sorted, inflation-dodging bike and we’re really looking forward to trying out the Triple B, which on the surface at least, seems to feature many of the upgrades we would recommend making to the Bossnut.
The bike comes in at £1,399 (with discount card, £1,600 without) and can be preordered now at Go Outdoors.
