Hi,

I have a 1996 Trek 5500. Does this take an English or Italian bottom
bracket? Is there a specific length?

Many thanks in advance.

English. Shell will be 68mm, spindle length depends on the crank. It's
probably a Dura-Ace crank, but the spindle length will depend on the
revision, and could be anywhere between 103-113mm. There should be a 4-
digit number on the back of the crankarm, beginning with a 7. Compare
that to this chart:

Hope that helps!
