Besides, If you drop from the 46x22 down to the 36 you will get the next gear, a better gear spacing, and a straighter chain line all the way down to 31.
2. Can I use the 36 with cog #1? > > Why not? It will work OK, but if you're going to be there for a long time, the 46x20 will be a little better. > > BIG APPLES KOJAKS *46* 36 24 *46* 36 24 16 83 65 15 83 65 18 74 58 > 17 73 57 *20* *67* 52 *18* *69* 54 22 61 47 32 19 65 51 34 26 51 40 27 > 21 59 46 31 30 44 35 23 24 52 41 27 34 39 31 20 29 43 34 22 > I am still debating whether one of these has any real advantage for me: > > > 36 24 38 24 11 88 12 92 12 81 13 85 13 75 14 79 14 69 16 > 69 16 61 17 65 19 51 34 20 55 35 23 44 28 24 46 29 29 35 23 28 > 39 25 34 30 20 36 31 19 > The 12 will last longer than the 11 and you have more useful gears off the 24 than you are showing. You will need a short cage FD, like the campy, to make this work without running the derailler into the chain stay, and still be close enough to a 38 to shift smoothly. > Don't wait up for me: I have been a gear nerd, freak, obsessive, fanatic > for over 20 years despite fixed gear riding and I love the subject.
