Bossnut's Big Brother has arrived, and he's fast, fun and so responsive to every twist and turn.
Calibre's Triple B truly is the big brother of the Bossnut family, combining everything great about these award-winning, trail-smashing bikes with a host of upgrades that all the magazines and riders were crying out for.
It uses the same superb frame geometry from the Calibre Bossnut Evo, with the addition of a 142x12mm bolt through rear end and the longer and more capable Rock Shox Reba RL forks, making for a much more aggressive bike.
SRAM's NX 1x11NX gearing ensures responsive and simple shifting with a huge gear ratio for even the toughest climbs, while the SRAM Guide T brakes give you superb stopping power when you need it most.
The WTB ST rims now have an increased internal width of 29mm, giving greater strength but also a much better tyre profile which also offers more compliance, and the Vigilante front tyre is now paired with the WTB Trail Boss tyre for greater grip.
You also have the new Kore Durox 780mm handlebar with its 5 degree up and 8.5 degree back sweep, and the confidence boosting Tranz-X 125mm dropper that comes as standard.
For those who want to move to a stealth dropper, the frame now contains both external and internal post routing, letting you choose whichever suits your style.
Available in sizes 17.5" (M), 19.5" (L) and 21.5"(XL) (subject to stock availability)
