Ok here is my set up: Frame: Limey Back wheel : Full chris king HD spaced on old cassetee spacers +14t cog Cranks: Middleburn n Ti bash ring + 16t cog (square taper) Chain: KMC Kool fat one BB: Shimano , some long one. Right, well i baught this thinking it'd solve my problems, guess not. Firstly i tried to set it up on the outside of the hanger, but the tensioner doesnt go far enough in to get anywhere near the rear 14t cog. If i move the cog so that it is inline with the tensioner , then both the tensioner and rear cog are majorly out of line with the front (obvious problems). So then i tried to mount it on the inside, yeah i could get it in line but when i put wheen on everything rubbed off the spacers and the wheel didnt wanna move. Getting despaterate now, have even been thinking of getting rid of this curse and going 20", but i'll prolly even get problems with them! Help !?
