The
traditional method of measuring frame size was based on studying
a pool of accomplished cyclists and making assumptions. For example,
if cyclist A and B have a leg length of x and they are riding
a frame with a 58 seat tube, then if cyclist C has the same leg
length, he should also ride a 58, and so on.
 This
concept is the foundation for all sizing systems in use today.
However people are creatures of nature and as such we are all
different. We do not come out of nice moulds; we all grow differently.
Therefore it is not only the length of a limb that plays a role
in this puzzle, but size of joint, orientation of the joint, symmetry,
fitness level and flexibility of the individual.
A new perspective was needed and therefore The Serotta Size-Cycle
was born. The Size-Cycle is essentially an infinitely adjustable
stationary bicycle. On it a trained technician will help you determine
the optimal cycling position for you, based on your body, your
fitness and your flexibility. From your position, the technician
can then help you make the optimal decision on frame size selection
and component selection. This will insure that your new (or newly
fitted) bike will deliver the maximum performance. You will have
maximum power, maximum comfort and maximum endurance. No hocus-pocus.
Just the right fit.
A Serotta Size-Cycle
and appropriately trained technician is available in the form
of James Huggins, of Rock 'n' Road Cycles. If you like what you
hear in this section please drop
us an e-mail with your details and we will be happy to pass
them on to James. James also imports the complete range of Serotta
bikes from the USA so again if you are interested in further details
drop us
a note and we'll do the necessary.

Size or Custom?
A
properly designed custom bicycle takes your biomechanical fit
into consideration along with over-all balance and desired ride
quality of the bicycle. Ideally everything is proportionate.
Bigger people need bigger, stiffer, longer frames, longer cranks
and longer stems. A properly proportioned fit is just as important
for mountain bike cyclists as it is for road cyclists (and tourists).
Extreme conditions (very steep descents and climbs), abrupt
sharp turns etc, make weight distribution a critical element
of performance capability and safety.
Who needs a custom bicycle?
If you cannot achieve proper position on a bike even while changing
seatpost and/or stem you may be a custom candidate. If you can
achieve proper fit on your bike (or a new stock model) but find
that you end up with a disproportionately long or short stem,
or if your seat is out of travel or if your stem is dangerously
high out of the frame, you are a good candidate for a custom
frame.
