what is a 73mmE type bottom bracket?

Can I use a Truvativ Gigapipe Team Ti Bottom Bracket for my 2001 SB?

speedgoat's site says it is not for 73mm E-type....

Thanks

You are fine

E-type bottom brakets are for bb mounted front deraileurs (see pic below). Only Shimano makes (made?) the special e-type bb. They are fuctionally the same but are adjusted so you can fit the front derailleur mount and still maintain proper chainline.

The SB doesn't need an e-type. You can use a Gigapipe and pretty much anything else just fine. You would be hard pressed to actually find an e-type bb.
