Chain ring upgrade-- Is it safe?
Hey all. A build of mine has a 68.5cc with a 44 tooth rear chain ring. Gets above 30 easily, max of 39 downhill. I was curious if it would be safe to upgrade to a 36 or lower tooth chain ring. It would be cool to get some extra speed out of this thing, but would I be seriously compromising safety, structural integrity, ability to start easily, etc...?
