It's possible to add spacers to the axle of the ASC to bring it out to about 115-117mm. I would then have then have the rear end of the frame cold set to the required spacing and the dropouts aligned perfectly - it will be very easy and will not show - after all it is only 2mm per side. It is very important when using Sturmey gears that the dropouts are spaced correctly - incorrectly spaced dropouts are the major cause of axle breakages on Sturmey hubs. Sturmey axles are very hard - they rarely bend but do break. Standard fixed wheel hubs are either 110mm (old British standard) or 120mm across the locknuts. I am sure it is possible to respace either to your new rear end dimension - its either a question of adding about 5-7mm or taking away about 3-5mm.
