i have recently changed my rear cog from a no make 16t to a dura ace 15t and now my chains overly loud? i have sorted out my chain line to near perfect by using washers behind my chain ring and have tried diffrent lubes but the noise is still there! are dura ace cogs known for being loud? i really dont know...
cheers
Assuming track ends or rear facing dropouts then have you checked the alignment of the rear wheel? Look at your rear cog and chainring directly from above ... are the teeth fully centered between the chain links? If your rear wheel is aligned even slightly off, it can cause your cog / chainring teeth to pull diagonally against the chain, resulting in noise at the point where the teeth come into contact with the edges of the chain.
Going to get flamed to fuckery here, but I actually find that TWO tugnuts are great for micro-adjustments to wheel alignment.
