Your problem is probably with the crankset instead of the hub. If your using track hubs, your limited in adjustment. Are you using a double crankset with the chainring on the front of the spider? If so, move it behind the spider(where the small ring usually goes). If you're already on the small ring side, you might have to change BB length. hIf you're using a track crankset, you should be using a 109mm bottom bracket.
