The hardest thing is.

The hardest things to do on a bike are
1) Wrap handlebar tap
2) adjust a front derailleur.

I've been having a time setting up my front der. with the new crankset. Thankfully I had a chapter from Barnett's Manual.

24 pages of how the front derailleur works and step by step for setting it up. It seems to be much better though still slow to go to the big ring.
