That’s about 18 minutes too long unless you are doing a new install. Then it’s about 10 minutes too long.

Just sayin’

Edit: Just to be clear, not all front derailers are equal. Shimano’s more expensive offerings are less forgiving in their setup. An Ultrega derailer is a wonder of channels and sculpting and guides to help in the shifting. Unfortunately all that metal work gets in the way and rubs in more gears that occurs in their lower priced front derailers. A Tiagra, Sora or Claris front derailer has fewer bells and whistles and they are better for it. They accommodate a wider range of gear combinations with less rubbing. The same applies to their mountain bikes. Deore and lower is generally better than anything higher.

Additionally, the position of the clamp can make a large difference in performance as well. For Shimano, a top swing clamp is far superior to a bottom swing.

All that’s goes out the window for SRAM...at least for mountain bike front derailers. Not a one of their front derailers is bad from top to bottom.
