Calibre Triple B press release

After immediately selling out of our limited edition (250pcs) Beastnut bikes in 2017, there was high demand for a permanent, higher spec’d Bossnut model. We quickly got to work on designing a bike to take Calibre a step forward in the mountain bike world and after months of thorough testing in some of the most demanding bike parks and challenging races across the UK, we’re proud to introduce the £1399* Calibre Triple B.

The extra cash gets you a bolt-through back end for increased stiffness, a longer travel, higher spec’d Rock Shox fork that slackens out the head angle to give you a more gravity focused ride, a dropper post – often Bossnut owners first upgrade and a pair of SRAM guide brakes. These upgrades make the Triple B the go-to full suspension bike in this price range.

We took the Triple B to Wales to show off its capability both in the big mountains and on technical bike park trails with Cadair Idris and Revolution Bike Park providing the goods. Watch the video to see how it gets on.
