Ghost ring works realy well !!! , i was going to use a tensioner but couldnt make my mind up witch one to get so when i put it all together i thought i would give it a try ,got to say though there was very little slack in the chain when joined and to be honest i just didnt have the bits to keep trying different ratios , had to put the front ring on the inside of the spider and make sure that the chain line was spot on , i recon i can move it back at least one more link before i have to shorten the chai again
