I agree. I pedal over to base of Mt. Tam in one gear, switch to the second for the climb, then back to other gear for descent and ride home. I do that a lot, on all sorts of varied Nor Cal terrain.

To: rbw-owners-bunch@googlegroups.com Date: Tuesday, January 29, 2013, 10:40 AM In Sonoma County and Oregon's Willamette Valley, there are great valley rides that dead end into seriously steep climbs, often dirt. Having two fixed gear bikes on the same ride more than doubles the fun.

OTOH, I can see rigging a ss with two ratios, one for road and one for off road: the Dingle cog is excellent for that. I'd love to have a light, ss 29er with, say, a 39X17/21 for a 67 on-road gear and a 54 off-road gear. One day, God willing. While I think multiple sprocket and cog combos on what is designed as a ss is odd, I do sympathize with the conflicting desires for simplicity and multiple speeds. IMO, the good ol' AW is the way to go. Long ago, short of cash after buying my first decent road bike, I hacked an off roader out of a horrible Schwinn 3 speed with a 36 ring and an 18 cog. With the roughly 26" wheels, this gave me gears of 39, 52, and 69 inches which suited me (this was almost 25 years ago when I was young and buff) off road. (I remember riding with my flame at the time over a jeep track with multiple stream crossings and enjoying watching the water flow into and out of the rear hub. It continued to work fine until I finally abandoned the bike near a dumpster with the usual "free to good home" sign.

Some, like Colin, go for essentially two gears, as far apart a practical keeping the matched tooth difference. He's done a TON more riding than I have with this set up so it's obviously very effective! Others try to get 3 or 4 different ratios out of the 2x2. 3 is pretty easy, but getting a 4th useful ratio while staying within the 8 tooth range of the QB/SO dropout is tough. Does anyone have a 2x2 set-up with 4 useful gears within the 8 tooth range? -Pete in CT On Monday, January 28, 2013 11:18:43 PM UTC-5, Colin B. wrote: I've ridden 2x2 fixed for touring since 2007 - first an IRO Rob Roy and now a Simple One. I've done cross country and some significant tours on both coasts with this setup. I'm a fan of the widest spaced Surly Dingle (17/21) and when using it I match the tooth difference on a double up front (ex.: 44/40) so the wheel doesn't move when I switch between two useable gear combinations, ex.: 44/17 (high) and 40/21 (low). The White Industries Dos is as similar concept but a freewheel. Surly Dingle (fixed): http://surlybikes.com/parts/di ngle_cog White Dos (freewheel): http://www.whiteind.com/single speedgearing/freewheels.html With the Dingle and a matched-tooth-difference double gear changes are quite fast. (You don't need to flip the wheel and won't need to adjust the brakes.) In practice, you can have a wider range or more than two useable gears going the 2x2 route, but accomplishing these things is a bit more fiddly than my set up, and w/r/t touring I resist fiddly-ness. Up front, 42/38 is the sweet spot for me for loaded touring. This gives me 68" and 49". The idea is that the high gear is for 98% of the time. The low gear is for when you're heading north in Glacier on a long day, or nursing an injury. (Or if you're less religious or dumb than me, save your knees and use the low gear whenever appropriate.) The hardest part of this setup is getting the chainline perfect in both gear combinations - if you worry about those sorts of things. Overall, highly recommended.
