Which Bottom Bracket for a Shimano Tiagra 30x42x52 Crankset

[mikesbytes]

I need to replace the bottom bracket on my Giant OCR02-04 and according to the web site, the OCR02-04 is fitted with a Shimano Tiagra 30x42x52 Crankset, but no info on the bottom bracket.

This page shows a Shimano Tiagra double crank set and says "for use with tapered bottom bracket.

These are the bottom brackets I'm looking at at Torpedo 7, but which one do I need?

Much appreciate your advice

Use a UN26 BB, about $25 retail,
110mm for a double
113mm for a triple.

Thanks George, how did you figure that out?

BTW, I didn't know that sheldonbrown had an entire section on the topic

I looked it up in the Shimano book.
