I'm getting ready to put a new chain on my Miami Vice Ironman. So I've posted although I can shift to my lowest gear (28t) with some hesitation, once there it makes more noise than I'd like with the RD pulley hugging the freewheel too close. So the question is will adding a adding a link to the new chain be helpful?
Currently running stock 105 components with a 7 speed gripshift shifters and a China shimano freewheel and original 31 year old chain (b screw is maxed).
