Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Calibre Bossnut Mountain Bike 2025 Dark Teal

Season:2025

Brand:Calibre

Code:25-706303-TEA

Calibre 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 Calibre Bossnut Mountain Bike. 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.

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