I do have three, though as of late I mainly use chainring 2 and alter the rear from there - hoping I'll see improvements if I only "wimp out" on hills half way. Was under the impression the largest cog was a bit too diagonal as a result but it may have been illusion / inexperience with the subject.Is the term "Alpine Gear" generally accepted? My googling took me to a page that used this term for this kind of gear, though it was apparently misused at one point to refer to 2x5 bikes. In other communities I belong to, once a term has a history of misuse, any use becomes misuse.Thanks,M.
