I am an absolute newbie and would like to use my bike for
commuting 5mi each way to work. I have acquired an old used
Specialized Allez road bike with Suntour GPX drivetrain
components. In my two days of biking to work, I am finding
that climbing bridge overpasses is a chore. (Didn't I say I
was badly out of shape?) Anyway, I think my gearing is not
in my favor. The chainrings are 52t and 38t Suntour GPX, but
the freewheel is a 7 speed with 19t to 13t. So the lowest
gearing I have is 54" which is tough going for me and would
like to make that better.
The questions I have are:
1. Can I replace the 13-19 freewheel with one that has 30+
teeth as the largest gear? I see a Suntour 13-30t 7spd
freewheel on Ebay and am wondering if there is something
with higher number of teeth on the largest gear.
2. Should I be thinking of adding a smaller ring, if
possible, to the two rings that I have.
3. How difficult is it to do these things by myself? I like
mucking things around by myself, but have no idea how
good I am doing it. I managed to reverse my drop bar to
allow me to sit more upright.
If I am able to keep it up for a while, then I will probably
have more questions.
