smaller ratio's and custom rear ends calls for custom fitting.. sometimes you gotta bend the "rules"

 with the chainring in a different location it just means that the shift pins and shift ramps are in a different location respective to the crank arm. A rider may like his chainring to grab the chain on a particular position of his chainring so his crankarms are in a particular relationship with the bike. so... basically he wants the chain to be on the chainring right when he is ready to hammer. when your racing at his level you cant lose any time. even a half second of turning your cranks another 90* may be the difference in winning. (thats what i think...)

 its a single ring with a guide...shift ramps are nonexistent here.

@scofflaw23-those bashring tabs are just super thick and dont fit the contour of most new cranks as well, i had to shave mine down to fit the cranks, as im sure the mechanics had to modify theirs a little bit
