A bottom-bracket made for 46mm pressfit can be threaded up to a fit for a 47mm bottom-bracket and will have approximately a 46mm inside diameter. The T47 standard had a shell width of ...
Bottom bracket wrench for newer bottom bracket styles Crank extractor. A chain tool or chain splitter is used to 'break' a chain, in order to remove it from a bike or remove links, or to put a chain back together.

A less common headset failure is really a frame failure. The head tube can stretch, allowing a headset cup, which is supposed to be a tight interference fit, to become loose in the tube.

The value of the allowance depends on which material is being used, how big the ...
