Sorry but all of the archives to search are gone. As any trails are about 2 hours away, I'm giving some thought to running a 16 tooth for a less " busy " ride at higher speeds. Never carry a passenger. Just wanted to hear from those who have, or are using a 16. I'm aware running at higher RPMs is not a problem but just looking for a more relaxed higher speed ride. Sure appreciate comments from thos who have tried a 16 tooth. Many thanks.
