Why is moving the rear wheel only minimally important? I thought that was the whole point of the long, track (sorry, Sheldon) dropouts.
Now if you need more than your dropouts can handle, then yes; and getting, say, a 70" road gear with a sub 50" dirt gear will usually exceed dropout capacity if you try it with just rear cogs (let alone just chainrings). Or perhaps fenders might not let you use the entire dropout capacity. But otherwise, that's what long dropouts are for! What do you mean by "the gearing change is quite a bit more noticeable"? (This is not a jibe, just a question.) I've not used track ends, but I find that I can accomodate six teeth even in the rather short horizontals of my gofast Riv fixie, tho' I start with the axle almost touching the end of dropout when I'm using the 46/15. But I did try a 21 just to see, and the QR still clamps on dropout, not air. No fenders, of course, and this with a combo that just happens to have the happy, very-rear-edge position for the smaller cog. And that gives me about a 20 gi difference: 75 to 54. The retrofit 1010s on my Riv commuter fixed can (theoretically) accomodate even more, but then the rear fender also limits things. Personally, I have bailout gears more as theoretically satisfying options rather than much used alternatives; I finally settled on a 63" gear for my ss off roader because it was a decent compromise, for my tastes and abilities, between flat sand and dirt hills, and flailing despairingly on the flats. I'd rather walk up dirt hills than try to spin 175 mm cranks on a 60" gear on flat pavement! Patrick "who says you can't obsess about gears when riding strictly ss and fixed???"
