I'd like to get a clearer perspective on the pros and cons of a tensioner. Thanks
Wouldn't the chain tensioner negate that weight savings? If I am going for SS or IGH I wouldn't really want a derailleur that really isn't. I would rather just properly tension the chain if I could. Save on weight, have less moving parts and save some money buying a tensioner. The only reason for a chain tensioner is for bikes not designed for SS or IGH and since you haven't bought the bike yet there is really no reason to consider it.
There will be some friction and it won't be very smooth unless maybe you replace the pulleys with nice ceramic bearing'd ones and used a nicer grease.
