Speaking of Regina FW's, anyone know a source for a 28T inside cog? The cogset I salvaged from the trashed body last weekend turns out to be well spaced for my use except that the inside 31T needs to be changed to a 28T, about the most an NR RD can be made to handle.
Two observations, Jerry -
1) Getting the inside cog off, particularly a large one, can be quite difficult - even when you remember that it has LH threading. Lot more lever arm there for tightening it up while riding than on the other end (13 or 14), and time takes its toll, too. I had one go wavy not too long ago.
2) We have used 13-31 quite successfully with a NR and a half-step chainring set-up. Indeed, my Beloved Spouse's bike still has that, with a 40/45 front split. She has not found it a problem to be limited to a 93 top gear.
