The Synapse was just right. When I inquired about a medium Topstone, the LBS told me the Medium would feel too big.
If you want one of the bikes on your list and it is in your means, then ride them and see what fits you best.
I'm still thinking about that Synapse...

The frame also felt small compared to my previous road bike. I would likely have been happy with the Cannondale in large, however, the size/color combination was and remains unavailable. The online calculator for Specialized uses height plus shin length and returned a result of 58cm which is significantly larger than their medium sizes of 54/56. The 58cm also comes with the longest crank arms and I’m now getting sufficient knee extension without the seat post raised to the limit. The Specialized lineup does offer significantly more size increments than Cannondale which should help with the “Between sizes” dilemma.
Hello Trav1s, thank you for the help. I’ve been looking at bike sizing information, and I’m 172 cm tall with an 84 cm inseam. For the Topstone, I’m torn between sizes
S and
M. I tried both, and the
M frame left about 1 finger width of space between the top tube and my inseam, while the
S had more room. Unfortunately, I couldn’t test-ride them in the store to assess the reach.
The shop recommended the
M size, but I’m unsure how it will feel with the seat post raised. That’s why I was considering buying the
S so that the raised seat post would compensate for the size. However, as you mentioned, jevery57, considering your height on the Topstone, they recommend
M or
L. In your case, you mentioned that the larger size fits you better, correct?
Thanks to your recommendation, I also checked out the
Specialized sizing calculator, 42 cm leg, which suggests a
54 for me. Based on this, I believe the
M in the Topstone would be the right choice for me. Thank you both—I feel much more confident about my size now. It’s just a matter of deciding on a specific bike. Your comments have been greatly appreciated!.
