To address the complaint that Campagnolo should have put out the new lever shape in 10v, they did.
It's called Centaur. As much as some of us may hate to put something on our bikes that does not say "RECORD", those who want to try the new levers can do it, without replacing their entire drive train.
The thumb shifter has always seemed in a great position for me, but I have small hands and prefer to ride farther back on my hoods. Also, Ergopower was designed to run on Italian drops, which put the thumb shifter in the perfect position for sprinting. If you want to talk about gimmicks, let's talk about "anatomic" bars...
Also, front shifting for Campy has always been better than everything else due to its ability to trim. The Ergopower has a full 8 clicks of trim.
On Shimano:
7900 is leagues better than 7800. The new lever shape is great compared to what it was, and the new levers and sub-routed cables are far more pleasing to the eye,
BUT:
*The shift lever is still the brake lever.
*It's still not re-build-able/
*The chain and cassette wear out mid season.
To quote Spinal Tap:
"But these go to 11."
