Here goes.
Sheldon states 107-113 for XT M739, which is what I was planning to fit to my Heckler. So I went for the 113 as it has a fat seat tube. Decided after buying the BB to fit the Spesh cranks as I had better rings. I've not fitted the chain yet so I can't be certain but I think the mech will struggle for clearance with the big ring even at maximum adjustment. So I will probably end up having to get a 110mm. YMMV.
