| 352.1 | I replaced mine... You can, too! | RAINBO::WASSER | John A. Wasser | Wed Jun 17 1987 15:11 | 6 |
| > Can I change my bottom bracket without replacing the crank set?
Yes. The bottom bracket set must be compatible with the
threading of your frame (English, Italian, French, other)
and your cranks (the tapers are slightly different on
different brands/models of crank).

| 352.2 | Check tapers and cups for compatability too... | MENTOR::REG | Husqvarna Sonata fur A# saw und vood | Wed Jun 17 1987 15:55 | 21 |
| re (.1 re .0) ...and make sure the tapers are compatible too.
If you don't the potential problems can range between:-
Crank goes too far onto spindle causing chainstay/crank interference,
cranks may not tighten down on spindle.
Crank wobbles on spindle, even when torqued down real hard, may
not be noticeable immediately, but will show up soon as creaking
noises and a tendency to work loose very frequently.
Crank may actually split around its squared hole, this is can be
thought of as the "wood splitter effect".
Some horrid combinations of the above, any of which could be
very expensive.

(Oh, cup depth varies too {leave this one alone Gary M.}, so
check that too)

As .1 and .2 suggest, the bottom line is, yes, if it's a replacement
of the same brand and type, but if not, you're asking for trouble
except in special circumstances. Some cranks are copies of one another,
ie. the Sugino Mighty Compe is compatible with Campy Nuovo Record.

| 352.4 | Check compatibility very carefully... | SUSHI::KMACDONALD | Macarooned on a Dessert Island | Thu Jun 18 1987 10:07 | 8 |
| Often (not often enough) the M.O. catalogs have charts of which bottom
brackets fit which of their cranksets. The most common are the Campy -
compatible B.B's and cranksets. Be careful - some of the manufacturers
(Sugino comes to mind) have about 42 styles and sizes of B.B's to go
with their cranks, none mutually compatible. Also note that in most
cases, double and triple cranks require different B.B's.

| 352.5 | Sutherland's might be a place to check | WARLRD::JBINGHAM | John Bingham | Tue Jun 23 1987 21:05 | 3 |
| For compatibility check Sutherland's Handbook for Bicycle
Mechanics. It lists compatible pieces. I haven't gotten
the newest one but older ones were good on what fit what.
