Re:
Ok, the bottom bracket shell dimensions are as follows:
Width : just over 65mm
Thread depth non-drive side : 22mm
Thread depth drive side : 19mm
As I mentioned earlier, I fitted a lock ring to the non-drive side of the bottom bracket and that worked fine, or alternatively you could pop a spacer onto the drive side. I will include the lock ring and the spacer then you can choose. I used a normal sealed Shimano bb on the frame.
