Oh, and are you brazing in an eccentric bb shell to tension the link chain or using a mtb tensioner thingy?
I've got one of these:
Which clamps to the rear seat post (Esme legs aren't long enough for the frame yet) so by adjusting the height of this, and the height of the saddle together, plus a possible halflink, I hope to be able to tension the sync. chain okay.
The main drive will run from the front BB, with the adjustable BB doofer running the sync.chain on the non-drive side. I'd rather run it all on the left, but the sync. chain will be coming from above, and so will have to pass the drive chain. I could possibly do this if I could find a 32T chain ring for the granny ring on a triple, but I couldn't (The only short - 102mm cranks I could find had a fixed 32T chain ring). I did pick up a cheap Truvative tandem crankset, so can use that and run just one drive-side ring on that to the 8-speed Alfine. Once Esme is big enough for the regular BB I'll rethink it, until she's on her own bike and child no.2. is on this.

I hope that all makes some sense.
