Gearing question...chain sound
Hi, first time poster. I just had a custom bike built and everyone pushed me to get campy record components. Previous to this I had Shimano Ultegra. After putting some miles on the new bike, I have a few questions:
--My Campy is 50:34 up front and 12-25 in back. I am a bit surprised that when I am in my smaller ring up front, I begin to hear some chain sound when I am 3 gears from the smallest in back. I can trim the sound out using the left paddle while in the 3rd from smallest but as I go to the second and finally smallest, I can't. By the way, I have a Wipperman chain. Now I know what you are all going to say...you aren't supposed to cross chain lilke that anyway, but there are times when you have to for a few minutes and my lowly Ultegra doesn't make a sound in any gear. Is this normal? If so, it's a bit of a shame that I have almost 3 gears that can't be used. What then makes Campy so great? I love the ergonomics of the hoods but from a pure shifting point of view, I like the Shimano better.
--Also, the Shimano has 50/36 up front and 12-28 in back. With the Campy setup my ultimate lowest gear is not as low as with the Shimano. There is also not as much overlap between the high range (big ring up front) and low range as with the Shimano. In other words with the Shimano, the highest gear in the low range is higher and the lowest gear in the high range is lower than with the Campy. I like this becasue in practice I could be going along at 18 mph in the large ring up front and see a hill coming up...I can then switch down to the small ring up front in anticipation of the hill and still not "over rev". Then, I have 10 good gears to use as I go up the hill. With the Campy, I can't do this becasue when I switch from the big ring to the small ring the gearing is too low for the speed and I end up "over revving". So with the Campy, I have to shift from big rignt to small ring somewhere in the middle of casette. I hope that some of this is making sense to someone. I guess my question is...they must know what they're doing at Campy so what is the thinking behind the gearing? Am I missing something?
It seems that with the Shimano, I get more usable gears and a wider overall range of gears.
