Default Re: SRAM front drum brake hub

That is a trip eDJ! No wonder Dan has been bugging me ALL DAY to look at it! LOL

Why mess with the chain? drill a hole in the sprocket and use one of those brass cable stops. I belive your 1st drawing would be the strongest mechanical advantage (see disclaimer below).
The chain may add to mechanical advantage but IMHO too many moving parts. On that note, I would be drawn to the second drawing with one large pulley. My approach has always been build it and ask questions later.

Now I have to be on the lookout for a 26" coaster brake rim in the dump! LOL

Building 2nd kit in 6 years. Cheez this time. 1st one was a DAX.
