Step one of using the fit chart is finding your pad reach, and where you find it determines which frame and stem combinations will work for your fit coordinates.

• Mid-Pad: will drive you towards a frame and stem combo which pretty much centers your pads over the basebar.
• Pad-Range: similar to mid-pad, but accounts for the full adjustment of the pad by itself (i.e. how far can the pad go, forward and backward, without making any other adjustment like moving the pad wing or sliding the mono)
• Full-Range: shows you how far the system can go in both directions, again using the basebar as the center of the range

What would you use and why?

• Mid-Pad: where everyone should start, and where most people will finish. That is to say, the frame-stem combo you get by using this pad reach range is appropriate for most people most of the time
• Pad-Range: usually comes into play when the answer you got by using mid-pad includes basebar stack and/or reach numbers which you don't like...by using pad-range you open up the possibilities for finding a frame-stem combos which better matches your basebar location preference.
• Full-Range: this takes pad-range to the extremes, to handle the surprisingly large range of fit coordinates that actually exist out in the real world (contrary to what some mfr's would have you believe). If you and/or your fitter determine that the best pad position for you is well outside of ST-norms, we're not here to judge...we're here to find an SC combo that works for you. An example would be someone plugs their pad reach into "mid-pad" or even "pad-range" and finds no solution (i.e. reach is pointing to one frame size and pad stack points to another). It can also be used to deal with extreme cases of the basebar location scenario I mention in pad-range above.
