Goes to show we’re reading the Herse emails. The Dancing Chain book, from years ago speaks very highly of the Nivex design. And along with the placement location, I thought having a chain rest on the inside of the rear dropouts, where you could shift the chain completely off the rear freewheel pretty cool. Being able to set one up, and adjust the desmodromic cables is probably beyond me, though. Too much? There’s a lot of bicycles, and their parts that are too much for me, but a handmade steel bike with an almost handmade derailleur system is going to be expensive. If Gugie was to build one for me, it would be a 126mm with the cable rest and a freewheel. How much? It would be worth every centime.
