ok a bit of searching, ENO are single speed modern stuff (probably explains the forum section we're in )
so err, longer bottom bracket or spacer the rings out EDIT cannot spacer the ring /EDIT
from White industries site...
Bottom bracket: The ENO crank is designed with an extremely low Q factor: 160mm ENO; 142mm for VBC. With a 68mm BB shell we recommend a 113mm square tapered bottom bracket, however, some frames have wider chainstays and need a longer BB. By simply taking a few measurements on your frame you can determine a suitable BB spindle length for your frame. First measure from the center of the BB shell back along the chainstay 180mm. At that point, measure across the stays. Your measurement should be from the outside of the stay to the opposing outside stay. If the measurement is 135mm or less, use a 113mm BB. If your measurement is higher than 135mm, then add the difference to the base 113mm to determine you BB length. For instance, if the chainstay measurement is 140mm then the BB length would be 118mm.
What do you get as your length.
Though if you're happy to space the bottom bracket out, it seems fine to me, my FC-M900 runs very close to my frame and that's an old steel one, but if you take the measurement above as a guide to how far it should be away.
