I've just bought a second hand bike for one of my kids and need to replace the bottom bracket. It is an old style cup and cone type, can I simply replace this with a sealed unit like a Shimano UN55?
The bottom bracket shell measures 68mm which I think makes it English thread? The spindle/axle measures 115mm. There is a plastic white liner inside the bottom bracket at the moment, am I right in thinking I can just whip this out to make space for the new bottom bracket?
