That means I have to use 10 speed derailleurs with 10 speed levers even though it would be cheaper to get 11 speed derailleurs. Or a 9 speed derailleur but those are even harder to come by. Good thing I've decided to disassembly my 62 cm Eddy Merckx Corsa Extra and sell the frame/fork and keep the 10 speed parts for spares. Also I have two or three Campy Triples I have to sell off to make more space. |

Front doubles in '9 speed' boxes are still plentiful and cheap, not different in any way from the later '10 speed' marked changers except the lettering. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

Granted the "standard" fronts are the same. On both the 9 speed front compact and standard I would always use a Deda Elementi Dog Fang to stop a dropped chain when moving to the smaller ring but you can't do that with my new Colnago because the seat tube is teardrop shaped. |
