Help with Adjustment of front derailler

Hello new to this fourm,
I have a Lemond with Shimano Ultegra, I have had the bike in my local shop every year to get it tuned up. Now I thought I will try and do the work myself. How do i adjust the front derailler it refuses to go into the big chain ring in front. I have a triple front ring.
thanks for the information

Try increasing the cable tension by turning the barrel adjustor counter-clockwise.

The first thing to do, is make sure your rear derailleur is set up right. From there you go to checking the adjustment of the front der. limit screws. Once they are ok, you mess with the cable tension to fine tune.

Close, but not good enough.

Front derailleurs are sensitive to the sequence in which you make the adjustments. Start with the position of the derailleur on the seatpost. Then set the low limit screw, cable tension and high limit screw in that order.

My experience has been that most of the time when psople have trouble with a front derailleur the problem stems from either the position of the derailleur on the seatpost or the position of the low limit screw.

Yeah; most people don't position the cage close enough to the large ring (1 - 2mm).
