At the
risk of stating the obvious, women are a different shape to men - they therefore
have different requirements to ensure their comfort on a bike.
You don't
have to ride the "step through" or "woman's bike". These
are throwbacks to when most women rode in skirts. If you prefer riding in
shorts, or leggings, there's no reason you shouldn't ride the same kind of
"diamond frame" as a man.
As
a woman your main problem comes when trying to get your "reach"
sorted out, i.e. how far you stretch out on your bike. For women of 5'5" or
under, this problem will be especially pronounced.
One alternative
is to have a bike built specially for you. This is expensive so you'll be
pleased to know that there are many changes that can be made to an off the
peg bike to ensure it fits you. A CoBR member will suggest you make these
kinds of alteration.
As
most women have narrower shoulders than men you may therefore need narrower
handlebars. The bars should be roughly the same width as your shoulders.
If
you have MTB bars you will probably not need to purchase new, just ask your
CoBR member to cut down the existing ones.
Fit
a
shorter stem (the part connecting the bars to the bike) to reduce the
distance
between your saddle and the handlebars. This will allow you to sit more upright.
As
you
also have smaller hands than men you also need to adjust your brake levers
so your hands can easily grip them. If this doesn't work, you may need
what
are called "short-reach levers".
And
finally
- if your inside leg is between 29" and 33" you will need 170mm
crank arms (the items to which your pedals are connected). If shorter
than this, go for crank arms which are 165mm in length.
