Here's the end result---
A 14-17-20-24-28-34 freewheel. Should I make any adjustments?
Now, how should I gear the crankset? 42-46, 42-47, or 42-49 (the chainrings in my spares), or something else?
Your wise "vintage half-step" gearing advice is appreciated!
That's exactly my 7sp cassette, minus the 12T. A 42-46 should give a very good 1/2 step (9.5% vs mean step of 19.4%). The tall gear won't be super tall but it should do!
