<p>The calculator above is designed to help fitters trained in the F.I.S.T. tri
|
||
|
|
bike fit protocol to generate geometries for custom triathlon bikes. Note
|
||
|
|
that the inputs required to use this calculator include "stack" and "reach."
|
||
|
|
These values are described at length in our <a href="/Bike_Fit/The_F.I.S.T._Method_for_fitting_triathletes_to_their_bikes_16.html ">tri bike fit articles</a> on Slowtwitch.com.

|
||
|
|
</div>
|
||
|
|
<p>
|
||
|
|
Even if the fit is performed correctly, pitfalls loom. You must have the
|
||
|
|
tools to accurately find the stack and reach of the bike that fits under the
|
||
|
|
rider. The fitter is required to account for the stem length, stem pitch,
|
||
|
|
height of the stem clamp, headset upper stack, spacers under the stem if
|
||
|
|
any, and of course the choice of aerobar. He then must have an accurate way
|
||
|
|
of generating the stack and reach measures, using either a fit bike (best is
|
||
|
|
the bike made by Exit Cycling) that accurately generates these values
|
||
|
|
(taking into consideration <a href="/Bike_Fit/Fudging_for_negative_reach_123.html">negative reach</a> if applicable), or he must use an external tool, such
|
||
|
|
as Serotta's X/Y tool.
