Which Parts Do You Need To Build A Mountain Bike?

Building your own mountain bike can be a daunting task, but with some patience - plenty of Youtube videos and the right components, mountain bikers can design and build a mountain bike which perfectly suits their requirements and needs - proudly showing off their creation out on the trails.

At Westbrook Cycles, many of our customers come to us for a range of mountain bike frames and components which are then used in either the ground up design of a mountain bike build, or as part of a program of MTB upgrades.

Below, we list and comment on some of the most important parts and components that need to be purchased by anybody with dreams of building their own mountain bike.

Mountain Bike Component List

Below is a list of all of the parts you need to build your own mountain bike:

 

Frame

The starting point of your bike build, the frame can be either hardtail or full suspension - and can be purchased in a range of sizes. There are also many different frame materials available, including carbon fibre, steel and aluminum/alloy. The geometry of the frame will also need to correspond with the type of riding you want to do, with downhill mountain bike frames providing different performance characteristics to cross country mountain bike frames.
