Title: Nomad Bottom bracket size for chainlink?
Post by: Pavel on April 14, 2020, 11:23:52 pm

what square taper bottom bracket size is recommended for the Thorn Nomad, in order to maintain the correct chainline please?  I've got three 73mm Shimano bottom brackets, all with a different size, and I can't remember which one it was that came from the Nomad.

Depends on the chainset, the Rohloff chainline is 54mm with a screw on sprocket, 55mm with a slim slined carrier and 57mm with the wider carrier, if that helps!
I have two - A Stronglight double chainset with the ring on the inner position which requires a 118mm BB and a Thorn triple with the ring on the middle position which requires a 110 + 1mm spacer.
