With the new NWT rear end design the Bike Friday in both It and the Tikit have an Option
of the rear dropout tensioning the chain.
works with Belt drives too .

The Silk was their other Belt drive capable design ..

I own a Pocket Llama Disc With a Rohloff and the R'off chain tensioner (Rear Fold hinge between BB & Hub)

Yes Cycle Monkey in Richmond took over the Distribution of all, the R'off stuff .. QBP Imports just what they Want Direct.

The Rohloff USA service Center was in El Cerrito California .. next town Over .. That is where I Sent My Hub in for a seal replacement.

(the '04 and earlier Hub used a Nylon Seal , now they're Neoprene, types, just like transmission and engine seals in cars and trucks .
