Garthr,
Thanks for the very useful information! I am still working on completely understanding your most excellent gearing chart. Nice work! Do you have a suggestion as to the best (as in shifting ease and durability) chain for use with the IRD 6 speed? It, the freewheel, must be different in some important way to make a different chain necessary. What is the difference?
I see there is someone nearby who might have one:
Arizona Spoke

Cosmic Cycles? Did you once live in Northern Arizona?

You'll need a new chain. Your Mountech should be OK . (It is a long cage, for those that don't know) I can't believe you still using yours...... mine broke not long after I bought my Stumpjumper back in '83 at Cosmic Cycles .
If you use a good gear chart, you'll see the Shimano 6sp megarange FW isn't so great for
half step gears. I also use half-step gearing, so I'm very familiar with it. I wouldn't use that particular FW.
