How to choose a mountain bike bottom bracket

A bottom bracket is chosen at the intersection of two constraints: the frame on one side and the crankset on the other. Getting either one wrong makes installation impossible. Shimano, SRAM and Race Face cover all common combinations.

Which frame standard?

BSA (threaded) : 68 or 73 mm wide, the bottom bracket screws in. The easiest to fit and maintain.
Press Fit : the bottom bracket is press-fitted. The 89.5 and 92 mm widths (BB92) are dominant in mountain biking.
PF30 and BB30 : larger diameter, found on some frames.
The standard is engraved on or can be measured from the frame: width and internal diameter.

Which crank spindle?

24 mm for a Shimano Hollowtech II crankset.
28.99 mm for a SRAM DUB crankset.
30 mm for Race Face Cinch and equivalent systems.
An adapter often allows a given spindle to be fitted in a bottom bracket of another diameter — but not always the other way round.

Bearings: when should they be replaced?

A tight spot, lateral play at the crank arms or regular creaking indicates bearings nearing the end of their service life.
On a BSA bottom bracket, the whole assembly can be replaced in one piece using two spanners.
On a Press Fit, removal requires a dedicated tool and clean reassembly, otherwise it may creak.
Bearings ceramic reduce friction but require more regular maintenance.

When fitting

Apply plenty of grease to the threads of a BSA bottom bracket, or use assembly grease on a Press Fit. Observe the specified torque and do not forget the spacers: their absence causes most play and creaking after reassembly.
