Hi people, some advice please, i have just fitted a new kmc kool chain onto my bike after the previiuos one snapping and it is skipping a bit i have lined to mech up perfectly, the teeth on the middleburn ti bash uci up front are in good condition but the rear seam to be a bit sharp and need replacing, i am unsure weather or not replacing to 14 tooth cog on the rear will stop this skiping whe i pedal fast with pressure.If people have had the same problem with there new chain skipping please tell me and how you overcome this problem.I am running a normal komc kool chian not the mega fat one and i have middleburn isis uci ti bash upfront 14 tooth cog on rear.
