How to fit a threaded bottom bracket in 9 easy steps Threaded bottom brackets are still the most popular, here's how to fit one cycling
Before you can fit a new threaded external cup bottom bracket, you need to prepare the frame. The threads in the shell need to be clean and sharp. If after cleaning your frame's bottom bracket threads you notice any damage to the threads or that when you run your fingertip on them, they're not sharp and well defined, you should consider taking the frame to your local bike shop to have the threads 'chased', which cleans and defines them ready for a new bottom bracket.
Bottom bracket shells come in 68mm and 73mm widths. Depending on the width of your shell and the specific cranks you're fitting, you may need zero, one or two 2.5mm spacers. These slide on to the cups prior to fitting most bottom brackets have a guide sheet with them telling you how many you need and which cup to fit them to.One of the benefits of the threaded external cup design is that it's adjustment free, meaning you simply screw it in to the frame until it's tight.
Repeat the process for the other side of the bottom bracket shell. You'll realise the process is extremely simple and convenient to do if and when required. There's nothing, other than the spacers, in the way of adjustment to worry about. Once you know what you bike needs in terms of spacing that's it.Help us to fund our site
