Is the hard shifting on the front something to just
live with?
The shift from middle to largest front chainring is always
the most difficult with an STI bike, for two reasons-
#1: Technique. Most don't realize that you actually have to
# hold the shift
lever all the way against the stop for a second or two to
get it to make that shift. It's not that she's not pushing
it far enough, but probably not long enough. It's
something that most of us do automatically, but many new
riders don't recognize. I see this all the time on test
rides; when we explain what to do ahead of time, the
problem usually goes away.
#2: Cable tension could be too tight, so that the
# derailleur just barely
moves to the point where the lever engages, requiring a lot
of force to get it to the click. A bit less cable tension
and things more better, in some cases.
#3: Make sure the cable is greased where it runs underneath
# the bottom
bracket, particularly on bikes where there's a metal
plate the cable runs over (the plastic ones aren't as
much of a problem).
But really focus on #1, especially if it's a problem that
she has with the bike and not others. It may seem like
mostly a small-hands problem, but it often isn't.
