Can't shift to highest front gear I've been trying to propely adjust front gears in my bike, but failed to do so. I can't make the front gear to shift to highest gear. I can make it work when testing the bike while it's lifted, but can't make it work when actually riding it. I've followed this tutorial, but it made no effect.

Should I go to a professional bike service, or is there something more I can try doing myself?
Front derailleur adjustment can be tricky. It's worth following a step-by step guide.

I follow Park Tool's process. The process recommends adjusting the derailleur position so it is parallel to the chainrings, but I find I need to toe-out the rear of the cage slightly to get reliable upshifts to the big ring on my bike.
