ok so, when the sealed bearings get put into the bb, do you need a tool to actually get them in at all? are they not suppose to slip in any by hand?

haha, dude oyu got a lot to learn, try to read some of the replies i got back from my posts about cranks. but usually the bearings have to be hammered in. but if oyu dont want to risk breaking them, put them in the freezer for a day, itll compress (cold stuff compresses, hot stuff expands) then itll shrink like 1/3 mm. stick it into the BB right when you take them out of the freezer, itll slip right in. then wait until it heats up and expands into place garantee itll be a lot easierwink

Just USE GREASE, and then make your own tool to press them in. Get a large bolt, with two large washers and a nut. Put the first washer on the bolt and then put the bearing on, then put the bolt through the bottom bracket of the frame with another large washer on the other side, and then tighten the nut on the other end, it will pull the bearing in to your frame. Repeat for the spacer and second bearing on the other side.

Essentially, you are making something like this http://www.parktool.com/product/home-mechanic-bearing-cup-press-hhp-3 but just with a simple set of washers, a bolt and a nut on the end.

You can use a hammer, but you just have to be careful, and you probably want to try a rubber mallet at first.

That freezer thing. Damn. I would rather do that than hammer them into some frames. Putting bb cups into American frames especially. I never thought of that either unsure I have been so confused lately about everything for some reasonsad
