107 will bring the non-drive side crank in ~3 mm towards the frame.

113 will place the drive side ~3mm further from the frame.

That is assuming you stick to Shimano bottom brackets.


Won't 107mm move both the drive side and none drive side in by 1.5mm and the 113mm move them both out by 1.5mm each? Or are the bottom brackets offset to only effect the drive side?

107 and 113 are the original chain line lengths (with super low profile cranks, eg m900, giving 47.5 and 50mm)
110 was a later in fill and people have measured it and it is just a none drive side Increase of the 107. I always thought it was as you say but was shown otherwise a few years back. Think its all on this forum somewhere. I cannot vouch for other makes of bottom bracket but I'm sure in Sutherland it says,that's the standard.
