Title: bottom brackets
Post by: Nickgtmx on December 29, 2015, 06:19 AM

Hi everybody, I'm a newbie to this site looking for a bit of advice on bottom brackets. I bought some parts for my sons bike for Christmas , but having difficulty finding bearings for the crank. I will attach a picture of the crank . The bracket shell is about 41.5 mm internal diameter. Hopefully somebody will know what you call this type of bottom bracket . Cheers Nick.

Hi and  :welcome

You need to pop up a picture of the bike's bb as well as all the bits you have and then you'll get an answer :daumenhoch:

That looks like it just uses a loose ball BB the same as a one piece crank?   ???
