I'm an unabashed triple fan. Both my commuters have 'em and I wouldn't have them any other way. When set up properly, the triple should shift crisply and easily in both directions between all three rings. With time and practice, I've gotten both my triples to shift just as nicely as both my doubles.

I like the Park Tool book and web site too, except for troubleshooting derailleur indexing. Then I find the Shimano information (either on paper in the box, or on the web) to be more helpful.

I refer the OP to the Shimano link dedhed supplied above, (Thanks for saving me the trouble of finding it myself!): http://techdocs.shimano.com/media/te...9830606982.pdf

The troubleshooting section is in the lower right corner. Your problem is the second on the list, "If shifting is difficult from the intermediate chainring to the largest chainring."

The cure is: "Loosen the top (H) adjustment screw counterclockwise (about 1/8 turn)."

It's fairly common to set this screw a little too to tight in an effort to be sure you don't overshift off the big ring entirely.

Oh, BTW, nice bike. A friend of mine has one. He likes his too.
