So i know ive been posting alot of new threads lately but i got a new bike and im totally unfamiliar with some of the issues ive been having on it compared to my old bike. The most recent is the slacking chain. I cannot seem to get it as tight as it was when i got it the other day( i changed the rimset for deepvs i had but the cog was the same so chain length is fine). is there a secret to it? ha I have no stand so i put the bike on the saddle and handlebars, pull the wheel back as far in the dropouts as can be and tighten, it still slacks like a MFer.
