Inner bearing
Bottom bracket in every price range
The bottom bracket - also known as the bottom bracket - ensures that your crank rotates smoothly in the frame. Although there are no specific mountain bike bottom brackets, road bike bottom brackets or gravel bottom brackets in the strict sense, different manufacturers set their own priorities in terms of the installation dimensions offered or the area of application . The different price categories for the same type of bottom bracket usually differ in terms of the manufacturing quality and the type of bearing.
Whether you want to replace a worn bearing or put together a customized bike, find the right bottom bracket for your bike here.

Which bottom bracket is the right one?
As manufacturers have constantly introduced new installation dimensions with their own names onto the market over the years, there is unfortunately no uniform pattern in the designations.
Once you have clarified your area of use , there are three pieces of information to consider in order to find the right bottom bracket for your bike:
- Installation type
A distinction is made between threaded and non-threaded bottom brackets. The diameter is also decisive here. - Housing width (also: installation width)
The part of your frame in which the bottom bracket is installed has a certain width. To do this, measure the frame from right to left, without the bearing shells or spacers. - Axle type of your crank (also: crankshaft)
There are systems in which the crankshaft is part of the crank (two-piece cranks, i.e. the crankshaft is firmly connected to the crank arm) and systems in which the crankshaft is part of the bottom bracket. There is not a bottom bracket for every combination of crank and frame. In some cases, however, bottom brackets can be used as adapters between systems or can be installed with the help of adapters.
You will need special tools for mounting and dismounting, such as a press-in tool, knock-out tool or puller. Manufacturers also sometimes recommend using assembly grease or threadlocker during assembly.
