I recently bought Nature Boy in Reynolds 853 and Mr Pink, both in 55 and they are way more comfortable for me, fit like a glove with 100 mm stem.
Now looking at getting either Big Block again but in 55 or Wabi Special (I rebuilt SH and Big Block for my wife so need to backfill the gap :-)). Still keeping my first Nature Boy for myself though, just gonna build it as another winter ride with 110mm stem and different bar setup
What made the 55 more comfortable for you? The higher stack? The difference in reach looks very minor on the geometry chart - is that what you found in riding it? Going through a similar debate - thanks for the help.
