  • Yup!

    Though I'm my case there's an EBB which simply doesn't provide enough adjustment when used alone. But I love the floating ring so much I'll keep it even when chain stretch allows me the remove a link and adjust only with the EBB (it's probably at that point already).

    It's a 53t Dura Ace 7400 ring but I'm keeping my eyes open for a comedy 55-60t ring to use instead, just as a willy-waving exercise. I can adjust the EBB to use any large ring. Anyone selling a dinner plate please do holla!

    If you were using ⅛" chain, you might be interested in the 65T TA Cyclotouriste that's sitting in my parts bin.
    For serious comedic effect, while not a strict geometric solution, any arbitrary curve of constant width should function as a ghost ring since some degree of backlash is necessary at some points in the rotation of any non-unity ratio chain drive in order to accommodate chordal action

  • Not sure if this mad bargain has been posted here... Sorry @knowthejo if you have done this already...


    Never saw it fully built but remember the frame and some stuff you were starting to gather for it, everything very very very beautiful! If we didn't already have a tandem that isn't being used... (although I've ordered the kiddy cranks adapter from sjs yesterday so there's hope...)
