Hello.

It is my understanding that stack and reach are the most important measurements when considering bike fit. With this in mind, I have the following question regarding potential bikes, and which one might best relate to the fit of my current bike (Lynskey).

The chart below shows Stack and Reach measurements for my current bike, as well as those for three other bikes. Two of those bikes, SystemSix and Foil are listed in size 51/52 and 54. The third, Cervelo, is only listed in size 54.



So when I look at the chart, would I be correct in thinking that the bike who would best match in fit is the Cervelo S Series?
Also, is there one of those two measurements which correlates better in order to obtain a similar fit? It seems that the SystemSix and Foil become quite longer in reach as the stack approximates that of the Helix....so in those cases, which would be of higher importance in getting as close as possible.

Thank you for any feedback with this.
