Calibre Releases The Triple B, An Upgraded Bossnut

by 1

Calibre, you know, that bike brand that keeps scooping up the awards with its low-cost mountain bikes? Well, the company is in the news again today with its latest variant of the popular Calibre Bossnut which it calls the Triple B.

The standard Bossnut is a good bike but customers have been asking for a version of the budget full-suspension bike with a little more travel, a dropper, and better brakes ever since the limited edition Beastnut sold out last year.

Meet the Triple B with upgraded brakes, forks and more,

Calibre’s answer was to figure out what upgrades customers were making to the standard Bossnut and offer a build with that upgraded spec off the shelf. The result is the £1399 Calibre Triple B.

The Triple B takes the award-winning Bossnut frame and adds a bolt through 142 x 12mm axle to the rear to stiffen things up and boosts the front suspension to 140mm that also slackens out the head angle for ‘a more gravity focussed ride’.

The Triple B gets 140mm travel forks which also slackens the front end.

Calibre also switched to more powerful 4 pot SRAM Guide T brakes and added a 125mm Tranz-X dropper post to the mix. It’s interesting that the Triple B comes specced with an externally routed dropper post when the Bossnut Evo was actually upgraded to accept stealth dropper posts, whether the frame on the Triple B is slightly different we’re not sure.

SRAM Guide R brakes and a Tranz-X dropper now come as standard.

The Triple B also gets a special black and yellow paint job, Triple B chainstay decals and a Triple B saddle.

As for the rest of the specification, it looks as thought Calibre has followed the tried, trusted and proven Bossnut formula including an SRAM NX 1 x 11 drivetrain, WTB wheels and tyres, Kore handlebar and RockShox suspension front and rear.

    I have just got one and the front triangle is the same as the evo and can take internal routed dropper – it just comes with a cheaper extrenal one. rear triangle is bolt thru so bit diff from evo. (might just be at the drop-outs though)
