I got a manic mechanic 40 t sprocket/ adapter and I cannot get my chain to fit . it was perfect with the 44 but I am in the middle of it being to small where it wont fit or too loose where its almost falling off. It works but is too loose and just about ready to fall off when I pin it. I put the tensioner all the way up and my wheel as far back as possible and its still too loose. I tried taking out another link but then its too ****ing short so I bought a new chain and am back to square 1. If the tensioner was higher it would be perfect but I am stumped. I read about a couple tensioner mods but before I try something I might not be able to do is there anything I am missing to try to get it tight again? My cruiser is a crazy size I have just about had to rig everything I have done with the bike
