Same geometry but smaller sizes, component changes and tuned suspension

Watch: Calibre/GoOutdoors’ promotional film for the Calibre Bossnut Ladies

Go Outdoors announce a women’s version of the popular Calibre Bossnut £1000 full suspension trail bike.

The ladies Bossnut will be listed at £1,299 but this price drops to £1,000 upon presentation of a Go Outdoors store card (which costs £5 to join). They’ll be available from November 19th onward.

We really rate the men’s Calibre Bossnut so this new women’s version offering a smaller frame size, some component tweaks and a custom suspension tune is a really great announcement for female riders looking to get in on the bargain Bossnut action.

Our verdict on the men’s Bossnut was: “With cutting edge geometry and a build kit that rivals similarly priced hardtails, the Calibre Bossnut is still well ahead of the development curve. From local lunchtime loops, to bike park blasting, the Bossnut proved time and time again that it’s a trail bike without compromise. It’s not just about going fast, however, it’s also guaranteed to put a massive smile on your face every time you take it for a blast.”


The decision to come out with a women’s version is basically due to repeated demand from customers – both instore and online – and the popularity of the existing Bossnut with female riders.

Calibre wanted to offer something specially but subtly tweaked for women and offer it in a size to accommodate riders who were too short for the 17.5″ size.

So yep, the geometry is the same as the men’s but the ‘contact point’ components have been tweaked to better fit females. Women’s specific WTB saddle and slimmer grips. The 15.5″/XS and 17.5″/S size models come with 740mm wide bars and 170mm length cranks.


The RockShox Sektor fork and RockShox Monarch rear shock both sport a specific tune designed to better suit lighter riders.

The paintjob has been altered slightly as well with the unsurprising choice of pink and teal as accent colours. The decision to use the ubiquitous pink will irk some riders but it could have been worse we suppose.
