[RBW] Re: Gearing question -
A 24/36/46 triple will shift beautifully, and the 105 double, as long as it's not one of the oddball current types, should work just fine. I've used my 105 FD-5500 from 1999 on rings with 26/44/48 and 24/36/50. I'm not a fan of adding more cogs(and the hub required) in the rear if the desired gearing variety can be done with a double or triple. I think 5-7sp FW's and hubs are terrific and highly versatile,. I've even purchased more NOS FW vintage hubs(Suntour XC Pro and Specialized) as I have a number of NOS 13-32 FW's, plus 14-34's(14/16/18/21/24/28/34) and 13-28's are still available as they have been for years. Try to find a 7sp cassette with those cogs, you won't. Try to find one of those, plus a 12t cog for 8 speeds, you won't. Sure you can go the Aliexpress route and make your own cassettes, which is fine if you already have the freehubs, but if don't already have the hubs , why bother ? Keep it simple.

[RBW] Re: Gearing question -
If you change the rear to a cassette hub, you will likely need to re-space the drop outs. I'm guessing your current freewheel hub is 126mm. Spacing.out to 130mm would be okay. My opinion would be just to change the chainrings to give the higher gear. The older 5 ans 6 speed wide range freewheels lend themselves well to half-step gearing. If you have a triple crank maybe a 44/48 or 42/46 with a granny gear of 28. If you are just commuting and running around with bike (vs touring or randomneuring), I would be inclined to just put on bigger chainrings. Cheaper, easier, better! My 26" wheel commuter had a 14-28 6 speed freewheel and I paired it with a 53/42 double and it was great like that. I do enjoy mashing up hills on my commuter though. I consider it anaerobic training. Because the bike sees so much winter use, I decided to make it a single speed and like it even better now, but the above gearing worked well for me.

Re: [RBW] Re: Gearing question
That's a good idea. I'll probably mix and match anyway to use the cogs I have, many of which are 7 speed. Right now the cassettes (BAs and Kojaks) are mostly 7 speed cogs with some 9 speeds, one or two Miche aftermarkets and mostly 9 sp spacers with two extra spacers between the big cogs and the freehub flange.

Re: [RBW] Re: Gearing question
Thanks, you are right. Yes, I did a replace all for tire diameter and forgot about the cogs. This wheelset is geared for dirt, so the high and low are useful. Anyway, riding fixed so much, I find myself not bothering much above 85: I can sprint such a gear to well over 30 at need, but usually just coast. And I find a gear of about 30 ample for most pavement hills, but grinding through sand takes as low as you've got. I will probably play around with these ratios; the 65 is fine for pavement or firm dirt with the Big Apples but a 61 (17t) instead of the 58/18 would work better for looser dirt cruising.

Looks good to me! I tried something similar for a while with a 34/22. Front derailer setup was fiddly. There was a fine line between getting it to shift to the big ring and shifting off to the outside of the big ring. I ended up switching to manual front shifting, then removed the rear derailer to make a sweet 2x3 setup (3 usable gears).

[RBW] Re: Gearing question
Patrick: I dunno if you've achieved your goal ...to make the perfectly accessible into something more complicated, One has 12 different gears and the other 11; doesn't seem too meaningful a difference, as long as you've got the range you want. Assuming you'll use the same 36T 24T rings, and that they shift OK now, seems like a simplification if anything. Your proposed 9 speed looks nicely progressive. Heck, just stick on the 9 speed and ride it for a while before bothering messing with the crankset.
