Calibre Bossnut Full Suspension Mountain Bike

Product details

The Calibre Bossnut is our MTB of the Year because of its well-earned, outstanding legacy. Capable of going toe to toe with any other trail bike out there, it's made its mark in the industry by providing a high quality build and handling in almost any conditions, without ever compromising on quality.  The Bossnut quickly gained a reputation as the go-to bike for new riders or people getting back into the sport. This sums up Calibre's ethos of producing bikes that provide affordable performance. The original bike went through 5 iterations and continued to grow in popularity until 2020 when due to covid our production ceased. It's been over 4 years since the last model launched, 4 years of redevelopment, testing and refining to create what we believe to be the best entry level performance mountain bike on the market. The bike that your mate who is into Mtb will recommend to get you hooked and become one of us! The original Bossnut built a cult-like following, what became clear to us was that people loved their Bossnuts in the same way that VW Transporter owners love their Bus. They want to upgrade them, personalise them and show them off. This meant that the new bike needed to be built around a solid frame that would be worthy of the upgrades that people make and not just get them into mountain biking but join them on the journey and stand the test of time. • Frame: 29” 6061 Alu, boost spacing, 135mm rear travel, tool and bottle bosses • Forks: RockShox Recon Silver RL, 29”, 140mm, stealth boost, 42mm offset • Rear shock: RockShox Deluxe Select R, 210x55 • Handlebar: 780mm, 31.8mm, 20mm rise • Stem: 45mm, 31.8mm clamp • Grips: Calibre lock-on grips • Headset: FSA No. 57e tapered, ZS44 upper, ZS56 lower • Saddle: Calibre trail • Dropper post: X-Fusion Manic LC, XS&S:125mm, M:150mm, L&XL: 170mm • Seatclamp: 34.9mm • Chainset: Shimano Cues 32T, 170mm cranks • Pedals: Flat pedals • BB: 73mm threaded BSA BB • Chain: Shimano Linkglide, LG500 • Cassette: Shimano, 10 speed, 11-48T • Shifters: Shimano Cues • Rear derailleur: Shimano Cues • Front Tyre: Maxxis 29” x 2.5” Minion DHF 60Tpi Exo • Rear Tyre: Maxxis 29” x 2.4” Forekaster 60Tpi Exo • Rims: 30mm ID, tubeless ready • Front hub: Shimano, 110mm, 32h • Rear hub: Shimano, 148mm, 32h • Thru-axle: M12, pitch 1.5, length 172mm, thread length: 20mm • Brakes: Shimano MT401 • Rotors: Shimano 180mm Please note: some minor specification changes may occur without notice.
