Bottom bracket tool

Sorry if this is a little vague…but worth a try . I have a road bike with a Dura ace crankset and powermeter. I want to service the bottom bracket but was told this required a special tool to remove this particular powermeter/ crankset combination. Does anyone know what tool would be needed?

Impossible to answer without knowing the bike you have (model & year) to check the specs or a good picture of the bottom bracket area at the very least.

Adding one resource of many on the web:

great information!
thank you.

Not sure if you were asking about the tool you need to remove the crankset to then access the BB (the link Chad posted will help with your BB tool), but this is the tool you need to remove the preload cap on the new DA cranks with PM.

At some point I’ve picked up a Truativ (now GXP) Screw fit BB removal tool and was delighted to find out the Shimano plastic BB tool that comes with Shimano BB’s fits securely in it.
