I just installed a new D/A 10sp front derailler for the first time. Noticed when shifting, the feel of the shift lever when going to the big chainring was very stiff - nothing like the buttery smooth action when shifting the rear derailler.
Most disturbing was the loud sound when shifting from the big to the small chainring. This isn't just a loud click but almost a bang, It vibrates the entire frame and makes a really harsh jolt felt through the crankarm. Not only that but it feels like it takes way too much effort to move the lever (going in either direction).
This can't be right. It's so different from the rear derailler's super smooth action, something must be wrong.

The 10s left lever has a higher mech advantage because it is longer. Ensure the BB guide is clean and lubed. Also ensure the inner wire and housing (REc 5mm!!) is smooth..if all above is set, it is as good as it's gonna be. The 10s front der does seem to have a stronger spring...

It does pop down pretty hard, it should shift up pretty easily though (atleast it does on my 2 DA10 bikes).

Does anyone have any ideas? Many thanks!

1. Mount on the correct (side) of the pivot?
1. Cable is too tight?
I would give DA10 a try if Shimano drops the price of the STIs by $100.
