I have an old Cannondale road bike I bought on Ebay many, many years
ago. Under the seat on the main post is a sticker stating 3.0 SERIES
ALUMINUM and under the on of the rear axle mount bars on the frame is
the stamped number 58071389057. The crank is a SHIMANO FC-1055. The
sticker on the front main post is still the old Cannondale logo with
the house, not the bars.
I have started getting a clicking sound and feel in the crank as I
pedal and I would like to check (or replace) the crank bearings. The
issue is I need to identify the bike before I know what bearings (or
cartridge) I need.
Any help or know where I can go to find out?
Thanks!

The serial numbers on the older Cannondales actually contain the size
and date of manufacture. I've forgotten the naming convention. I'd
guess that you bike is a 1989 and an 58 cm size.
No matter, the bb shell width is 68 mm and threading BSC. You can
measure the existing axel width and get a new bb. If it is a non
cartridge bb, when you take of the cup, you can measure a ball. I'd
guess ¼".

Great site!!!!

Looks like that one, the one on the left. The locking nut takes a
spanner wrench so it sounds like that is it.

I doubt it will, the click/clunk I hear/feel happens at the same spot
in the rotation every turn, especially if under load. I am hoping the
axle or bearing seats have not been damaged but I'll find out as soon
as I disassemble.
THANKS!!!! (Gotta love these groups!!!)

Start here: <http://sheldonbrown.com/tooltips/bbadj.html >. Scroll down a
bit for pictures of the two types of bottom bracket that you might have.
If you've got a cup and lockring like on the left, you'll need 1/4"
balls and appropriate tools as described in that article. If your bottom
bracket looks like the one on the right, the whole thing is a sealed
unit. If the spindle turns smoothly with the cranks off, let it be. If
not, pull it and replace it with another one with the same spindle
length.
