I'm currently running 10-speed Centaur on my crosser. The RD is actually a spare long cage that used to be on my wife's bike and is paired with a 12-25 rear cassette. I've decided that I'd probably want to go single ring up front and run a 12-32 MTB cassette if possible. So, here is the question. I'm pretty sure I have read that I can run a campy ergo 10 with a campy 10 RD with a 9 speed cassette without a shiftmate if I lock out the lower gear. Does this sound correct? I plan on running the 10-speed chain as well. Thanks for the help!

I run 10 speed shifters, 10 speed rd with a 9 speed cassette with a 9 speed chain. no shiftmate, works pretty good. adjust the limit screws and it should be it should be fine. for get the 10 speed chain, they are narrower, thinner, flexy and prone to breaking. they are only good for 1,500 miles and they cost at least 40 bucks. so why did you want to use a 10 speed chain?

newbie to the whole bike thing but have read quite a bit...I did not realize the chain would be weaker for 10 speeds (ie 20 speed with a double crank or 30 speed with triple crank). Only 1500 miles seems terrible, especially when the bikes with the 10 speed cassettes are usually more expensive. Is the chain a little longer on a 10 speed.

PS after getting a Giant OCR3 as my first bike I now realize a cross bike might be better suited for the rough roads I ride at my 240 lbs but so far (3 months and about 300 miles) and have not busted a spoke. And from what I have read, I could even get in some trail riding with a cross.

on a road bike, I feel I should have a lightest top notch stuff. but on a cross bike, I'm looking for durability and performance. and with the cross tires pumped up, it feels pretty fast and I don't feel like I'm giving up much to a road bike.
as for 10 speed chains: http://www.velonews.com/tech/report/articles/10011.0.html
thank you fogrider, and yes, I can see where lighter stuff might be ok on a road bike but probably not as desiarable on a cross bike. I read the link you supplied and also did a search on "durability problems with 10 speed chains" and found several articles and this forum which went into details over my head but I got the picture that light weight narrow 10 speed chains can break. some reported at low milage and others a bit better.

even for road bikes, I'm set up for 9 speed. with 4 bikes, I can't be spending 40 bucks on a chain every 1,500 miles.

thanks for the input. No real reason for wanting to use the 10-speed chain other than b/c I already have one. I'll shelve it a throw a 9 speed on there.
