Calibre Bossnut V2: sorted full suspension ride for under a grand!

In a world where bike prices only ever seem to head in one direction, bikes like Calibre’s Bossnut are a breath of fresh air. The predecessor of this bike showed the UK (and indeed the rest of the world thanks to a flat shipping rate of £10) that building a properly capable full-suspension mountain bike was possible despite a tight budget.

The original Bossnut cost £1,299, however next to nobody ever paid that price thanks to a hefty reduction offered to members of GO Outdoors’ loyalty scheme (£5 per annum) that dropped the outlay to £999. This latest version of the Bossnut builds on what Go Outdoors learned with its first bike but still honours that same aggressive pricing.

Calibre’s careful component choices and well-considered geometry were key to the success of the original Bossnut and so it’s no surprise to see subtle rather than radical changes.

As far as the frame is concerned, the Bossnut V2 features a slightly longer top tube and a fresh lick of paint. There’s the same linkage activated single pivot suspension delivering 130mm at the rear wheel, but it’s now via a new one-piece rocker link for a stiffer rear-end with additional clearance. Calibre states the Bossnut V2 will accept a 2.35in rear tyre without any troubles.

Simplicity arrives in the form of a regular 73mm threaded bottom bracket shell and full external cable routing.

The simple RockShox suspension combo of the Bossnut V2 is the same as that of its predecessor. At the front end of the Bossnut is a RockShox Sektor Silver, which matches the 130mm of travel offered by the Monarch R at the rear end of the bike.

Both units are air sprung, with an easily adjustable damping range that should suit a majority of riders just fine.

Talking of wheels, the WTB i25 rims of the Bossnut will allow riders to take advantage of a tubeless upgrade, that’s as soon as the standard fit 2.3in WTB Vigilante front and 2.2in WTB Bee Line rear tyres are worn out.

There’s no dropper post, it would’ve been unfair to expect one at this price, but the 31.6mm seat tube is ready to accept an externally routed item, which should be top of the upgrade list for anyone after this bike.

Any women looking at this bike should be aware that the Bossnut Ladies V2 exists, which features women-specific contact points, a lighter suspension tune and a different colour.

It seems like Calibre has played it safe with the Bossnut V2 by sticking closely to the formula that worked so well for the bike before it. At the same time, it’s now been more than three years since we first rode the original Bossnut and it’ll be interesting to see if this design still cuts the mustard among more recent competitors, such as Boardman’s Team FS or Voodoo Canzo.

We’ll be putting plenty of test time into this bike to find out so stay tuned for a full review.
