Trying to Identify Bottom Bracket Tool?
Hi have a hybrid bicycle with Shimano gears. The rear casset takes a shimano fitting.
What I'm interested in is identifying the bottom bracket so I can buy the correct removal tool.

Please see the photo attached.
There are 4 groups of 4 notches running along the inside of the bracket bolt holding in the bearings.
From what I understand I need a shimano tool of some description but I could be wrong.
the Internal crank shaft is around 16mm thick and the diameter. The diameter of the inside of the outer ring I need the tool for is somewhere between 28mm and 33mm (It's difficult to measure).

Please see the photo.
Any help identifying this would be greatly appreciated.


I would contact Park tools and forward your photo to them.
