When I was using a monocog 29er as my winter bike, I had a triple speed:
three cogs, three chainrings (the third, lowest gear was used for maximum
torque to drive through deep snow without bogging down) . All three combos
added up to the same total teeth but the change in angles was enough that
Yes, chain length remains the same in all cases - I guess what I meant to
say was 'rear center' (distance between bottom bracket and axle).
It's entirely possible a rear disc might work well enough over that ~3mm
range. I've never owned a disc braked bike with horizontal dropouts
allowing the
Thanks, Dave, good to know about the DOX 2-tooth gap fws.
Back to the question of disc brake and axle movement: the *chain length* will
remain the same; the axle will have to move to accommodate different size
cogs since I don't want a tensioner.* This of course assumes that one is
using
Patrick, I hope I am understanding what you are looking for, but the DOS
freewheels are still made in the two tooth differential versions; it's only
the three tooth differential version (16/19) that was discontinued.
I'm not sure if you are looking for DOS freewheels in this situation though
Thanks, but I don't want that complication. I want (if I can get it) the
simplicity of my Riv customer gofast: QR rear hub, Dingle cog, long
horizontal dropouts. I don't necessarily need these means but I do want the
same end.

The simplest solution is to also use two chainrings, matching the cog
difference (for instance, with a 16/18 Dos freewheel, use 42 and 44t
chainrings). Then the 44/16 and 42/18 have the same chain length, and the
rotor to pad relationship doesn't change.
Or just use a disc front and a rim brake
