Kona Sutra - Need Sizing Advice

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Kona Sutra - Need Sizing Advice

Hi All, I know this could be posted in the touring or gravel forums, but I know there's more traffic here and I'm looking for quick advice. My local dealer doesn't stock the bike, but can order it. I'm a long ways from anywhere I could ride one.


I'm looking to purchase a Kona Sutra for my backup road/do-it-all bike, but am in a sizing conundrum. I seemingly fall between the 56 and 58. 58 cm is my standard road size - my '16 Tarmac fits me like a glove. I'm 6'1" with a 35 inch inseam, long arms, short torso. Comparison between the geo of my 58 Tarmac, the 56 Sutra, and 58 Sutra are here: https://geometrygeeks.bike/compare/s...sutra-2019-58/


I'm surprised that although both bikes have a longer effective TT length, they both have a shorter reach than my Tarmac. The 56 Sutra more closely matches most of the dimensions of my Tarmac, and I'm 75% sure that's the way I need to go, however the reach of the 58 Sutra comes closer to my Tarmac (by 5 millimeters). The 58 has an 850 mm standover, which is at the upper limit of what would feel right - my Wabi Classic FG (riding a 58) has a standover of 853 mm which clears, but is closer than ideal.


My intended use for the Sutra is LONG days on mixed terrain (road/gravel/dirt). My conventional wisdom to size down in road bikes and up in MTB when in-between hasn't failed me yet - but this bike is not really either. More an '80s 29'er with drops...


My fear is feeling too crammed into a 56, but the seat tube length and standover on the 58 is not exactly what I'd like to see. If anyone out there riding a Sutra could share your experience and how you sized your bike, your feedback is greatly appreciated.

So in an attempt to either answer my own question or clarify the ask:

Since the reach on the Sutra 56 & 58 are only 5 millimeters different, I think I need to throw that out the window and focus on standover and stack height.

I already know I prefer the standover of the 56; the stack on the 56 cm frame is 27 mm taller than my Tarmac vs. 49 mm higher on the 58 cm. 49 mm seems a pretty big jump, even given I'm comparing race geometry to touring geo. Plus, I imagine leaving room for a bit more seat post should make the ride a touch more compliant. Double-plus, I'm likely going to install a dropper seat post and would like more than 2-3 inches to work with.

All this considered, it seems to scream "Get the 56" - I think I answered my own question. Anyone see flaws to this logic? Am I missing something?

I am 6'4" and have a 58 cm Sutra. My Madone is a 60 cm so it sounds like the 56 might be right for you.
