...What is the best sprocket teeth combo for easy freeway cruising to 120Km? I am in serious need to renew, and would like to make sure I use the best option.

Opinions vary yet the general consensus is 18/42. btw I've always run with oem combo 17/42. I am going to change as I have an 18/42 ready to install...all that's needed is a chain.
