MTB Bottom Brackets

The bottom bracket, a very technical piece:


You want to change your full-suspension MTB bottom bracket, but you don't know where to start? No worries, the bottom bracket gives the wrong impression of a complex part, just like the headset on a mountain bike. This is due to the multiplication of bearing, pedal and frame standards in recent years.
The bottom bracket allows you to connect the cranks between them, it's the connection between your mountain bike frame and your pedals. It's therefore important at first to identify the type of bottom bracket that will fit your frame.
This part being particular to the MTB, special tools are needed to change the bottom bracket more easily. You can find all the necessary tools on Alltricks.com.
 

Essential criteria to know when changing a bottom bracket:


To choose a bottom bracket compatible with your frame, you must be aware of the following criteria:

- the type of bottom bracket,
- the width of the bottom bracket,
- the standard of the bottom bracket,
- the standard of the crankset,
- the bearings' material,
- the crank axle,
- the inner diameter of the bottom bracket.

For the final aesthetic touch, you have the choice between many colours to tune your bottom bracket with the other equipment of your mountain bike.
On our Alltricks.com website, you'll find a wide range of mountain bike cranksets, among the best brands: BBB, ACS, Hope...

Find all our MTB cranksets at Alltricks.com at unbeatable prices delivered within 24-48h.
