Calibre has just released the latest version of its much loved Bossnut. In this video, Alan Muldoon takes the bike to Sheffield to ride it and to speak with Jonny from Calibre to learn more about it. Alan also shares his thoughts on the new Calibre Bossnut.
When Calibre launched the original Bossnut almost a decade ago, it totally changed the game. It was the first entry-level full suspension bike that was designed with the rider in mind, not just the bottom line. It could be ridden hard, had fun on, and the parts package was cherry picked with performance in mind.
Ten years on, and Calibre is back with the next generation of Bossnut. The new bike has more travel than before, bigger 29in wheels and an altogether sleeker aluminium frame. It has the same DNA though. Best of all it comes in five frame sizes to offer a better fit, where the size XS uses smaller 27.5in wheels to keep the proportions in check.
Combine the size range with the modern geometry and the new Bossnut is ready to shred. Yes, the price has crept up, but it now comes with a dropper seat post as standard, so that’s one upgrade you won’t have to make.
In fact, given the quality of the new frame, the Bossnut is designed for upgrading. Want to switch to MX wheels? That’s easy, because Caliber will have an MX shock extender to correct the geometry. In fact all of the spare parts for the frame will be made in Sheffield, so Calibre will be able to keep your Bossnut on the trails for the foreseeable future.
To get the headline price of £1,499 you need to be a Go Outdoors Club Card member, so it’s definitely worth signing up as this only costs £5.

Great concept of video also always good to get the insight from the designer/ company 👍
Looks like they simply repainted a polygon (again) and fitted a low spec, 10 speed 😂 really ! Groupset !!! Siskiu T8 looks almost identical.. same frame ? is only £200 more from go outdoors and has a MUCH better spec and miles better suspension.
Is that a bent spoke at 7:12
Need to make more. There always sold out
Change forks too 150/160mm and brakes
This looks like all the bike you need, great trail geo, if upgrading parts as you go, its got all the modern standards and external cable routing. I see a future where these are perminently sold out again 😂
Ouch! Should have perhaps routed that shifter cable UNDER the chain stay???
Looks awesome the right machine for everyone who loves going for a good blast around kicking ass 👊👍
Whats going on with cotic?
Sounds looks the part this or the voodoo canzo any one ?
They want you to have a bike that is worth upgrading but at the same time it doesn't have UDH, there is not a single 2024 big brand mtb that isnt transmission compatable. That decision does not make sense to me.
Such a good bike and so well spec'd for the price. I loved hearing the behind the scenes stuff on trying to spec a bike to meet a certain price point… I never thought about the components being made in the same location as the frame and/or assembly would cost differently. Congrats Calibre!!
Trek, specialized, santa cruz et al will sell you a 50% better bike for 500% more cash…..
Had a Calibre Line 10 for about 4 years now, been a good bike. New Bossnut looks good, a few upgrades could make it great. What trails was this filmed at?
Great interview and guest,thank you.
Cues 10 speed cassette with 11-48t is a great choice for this price point. Its going to have 95% of the ability of a 12 speed sram NX Eagle that has 11-50t. 10 speed components should also be more affordable to replace when worn out for people on a budget, which is what this bike is aimed at. A lot of affordable propper mtbs are going to be using this such as the entry level Merida Big Trail model thats available for around £800.
Nice bike great insight 🎉🎉🎉😊😊😊😊
It's a good bike for the RRP price. However with options like the GT Force sport online from £1200 at half price with very similar spec components, the same forks but the 160mm option on the front and 150mm at the back you have to wonder if it'll need a price cut to sell well.
