American Classic conversion cassette questions
I just bought a 12-25 10spd American Classic conversion cassette to allow me
to use my new Mavic Cosmos wheels with my new Campy 10spd Centaur drivetrain. I'm wondering though if it's possible to buy spare individual cogs to "convert" this conversion cassette to a different ratio, and if so from whom? Specifically, I'd like to be able to swap out the 4 highest gears, which come as two pinned-together dual "cartridges" of 19/21 & 23/25, to either 18/19 & 21/23 (which would effectively turn this into AC's 12-23 cassette), or 19/21 & 23/27, or perhaps 19/21 & 23/29. Note that the lower 6 cogs are as follows: 12, 13, 14, 15, 16, 17. Is it possible to swap any of them out to achieve similar results? Also, does anyone know the recommended torque setting for the Shimano-compatible AC lockring? -- Kovie zen |

Very difficult. The spacing on the AC cassette is not symetrical. The inner cogs are really close together. You can save a pile of $ by just putting a Shimano 12/23 cassette on. Increase the tension in the derailleur cable by 1½ turns and screw the inner derailleur stop in 1¼ turns. Go riding. You will never miss the 18t cog on a real Campy 10 sp. cassette. |

Thus, my 10spd drivetrain is effectively a 9spd, in terms of the gears I'm likely to use 99% of the time. So I suppose that if I ever need higher gears, I can swap out the 12-25 10spd for a 9spd 13-27 or 13-29, and never notice the "missing" gear. Still, there's no harm in exploring 10spd options. -- Kovie zen Hey Kovie, Sorry, I'm a little late (you already ordered from AC) but you should check out Marchisio's conversion cassettes. It sounds like they're a little more customizable then the AC cassettes in that you can buy individual cogs. Also nice if one or two wear out but the others are still ok. You can find them he http://anysystem.de/ So far my Campy 9s Veloce group is running fine with a Shimano hub and 9s cassette but should I ever decide to build a custom cluster then I'll probably order it from them.
