BOSSNUT

We think that your first mountain bike can get you hooked on riding. Creating a bike that makes riding fun and accessible has always been the priority with the Bossnut. Finding the right balance of components that will keep the bike at a price point but perform at a level that makes no excuses or compromises when on the trail.

The bike is now rolling on 29″ wheels, the travel has been increased from 130mm all round to 140mm on the front and 135mm on the rear. It is a capable, fast rolling trail bike that can take the bigger hits as your riding progresses.

We have seen how hard the previous generation bikes got pushed, from UK enduro racing to alpine seasons so we have made sure that the new bike is built to last. We developed a chunky custom tubeset and redesigned the forgings to strengthen every part of the frame. We have had our riders absolutely hammering them and nobody has managed to break one of the new frames. We have also taken care of the details, we’ve got space for a bottle cage inside the frame, improved cable management and added bosses for tool storage under the toptube. We’ve also gone for Boost spacing on the hubs adding stiffness and keeping the frame futureproof.
