Spa often seem to disagree with Stronglight on BB length.
Escape doesn't feature on Stronglight's site any more but fortunately Sheldon has a copy of an old table towards the bottom of
this page.
Much as I like Spa, they are not infallible, they delivered a wrong chain ring to me this week and they are definitely wrong on the BB length for the Impact triple (unless you are using it on a Tandem), so I would go with 113 mm
