I sure miss the granny gear that my MTB has but the road bike doesn't.
It's an old Shimano set from the early 80's when I had this bike custom
built for me. The usual, 42-52T up front and a sweat breaking 13-21T
corn cob in back. 130mm BCD and for some reason the bike industry has
never figured out how to allow granny gear with that. And I don't have
the required machines and welding gear to make one. Meaning the smallest
I could theoretically get is 38 or 39 which isn't any improvement to
write home about. Sooo ... after a hint in a German NG I want to get an
HG50 7-speed 14-32T cassette, hack it apart, take the five center
sprockets, reduce the wide spline with a file and mount them, keeping
the old threaded outer sprocket to secure it all. Hoping that the old
Shimano 600 derailleur will push the chain to the 28T sprocket if maybe
I mount the rear wheel slightly forward. 32 would be asking too much I
guess.
Of course after the last ride I noticed that when I rolled my bike by
hand the freehub didn't always do its clicka-di-click thing and
occasionally drove the pedals. So maybe I'll have to let some chainsaw
oil ooze in from the side. I can't part with this classic bike. It's
tempting but if I'd buy a new carbon frame deal I know my wife would
make me get rid of my good ol' Gazelle.

I know that feeling :-)
But I am used to this because many of my trips lead me into Folsom and
farther. That's at 200ft altitude and we live at 1450ft. Lots of ups and
downs inbetween.

Oh yeah, that it does :-)

I thought about changing out the whole works. But that would not be a
nice thing to do to a classic bike with a Gazelle Trim Trophy Reynolds
531 frame.
