Replacing your bike bottom brackets
There are two different types of bike bottom brackets: those that are pressed into your frame and those that need to be threaded into it. The latter comes in different versions, with the more modern offerings providing long-lasting durability. Press-fit bottom brackets don’t require a threaded shell but still have to adhere to strict standards.
If you’re not sure about the type of bracket you need, measure the inside of the bottom bracket shell within your bike frame. If you need assistance with this, please contact us and we’ll help further. Our range of bike bottom brackets also includes ceramic ones.
