Hey all, I was searching through the forums and one poster suggested that the best way to learn about a bottom bracket was to take one apart, so I am going to just that. I have a 2002 Specialized with a cracked frame, it's stripped of all the other components but the bottom bracket. I had a few questions regarding this:

1.) Which tools will I need to remove the bottom bracket. (The link is to the BikePedia page, if a actual photo would be better I will attach one tonight.)


2002 Specialized Allez A1 Sport

Bottom Bracket: Shimano BB-UN52, 118mm spindle

2.) Are these tools used for most bottom brackets? I have another specialized that I used to replace this bike, I assume it will work with that but do bikes like Treks and Cannondales use a different type of bracket.

Park tools has some great write ups but they list several different tool options so before I ordered anything I just wanted to be pointed in the right direction.

Thanks!
