G. Fisher XCAL BB replacement

I've just bought a used Gary Fisher XCAL and am wanting to replace the BB.
It has a set of Bontrager cranks.
The OG BB was an ES25 Octalink although I'm not sure if it was replaced previously.

I'm needing to know the exact size yo get.

Thank you.

Google says: http://www.vintage-trek.com/Trek-Fis...nualFisher.pdf 73 X 113. You could also pull it and look at the dimensions. https://www.sjscycles.co.uk/images/p...dium/50139.jpg -- assuming the person who replaced the first one used the right replacement spindle length. The longer spindles are probably more available.
