Fantom Cross - In between sizes

I am looking into buying a Motobecane Fantom Cross as regular road biking purpose and some light off-road riding. I am between sizes (and may have a slightly longer legs than normal) at 5' 11" height and 34" inseam, so am looking for some advice. Would a 56" or 58" fit better for me? I heard that for cyclocross slightly smaller is preferred, is this true?

Would really appreciate input from folks with similar body/frame dimensions.

Their sizing guide puts me right in the middle of 56" and 58":
49cm = standover 29'' fits most riders 5'1'' to 5'4''
52cm = standover 29.5'' fits most riders 5'4'' to 5'6''
54cm = standover 30'' fits most riders 5'7'' to 5'9''
56cm = standover 31'' fits most riders 5'9'' to 5'11''
58cm = standover 32'' fits most riders 5'11'' to 6'1''
61cm = standover 33'' fits most riders 6'1'' to 6'4''

I'll chime in as no expert what-so-ever, but I'm 5'11" with a 34.5" inseam, so we are pretty similar for sizing purposes. For further reference I run 78cm from the middle of bottom bracket to the top of my saddle on all my bikes. That Fantom Cross in the 58cm has a 57cm effective top tube, and in the 56cm size has a 56cm effective top tube. For the past few years I've ridden a road bike (CAAD10) with a 57.5" ETT, but recently purchased a road bike (Bianchi Sempre Pro) with a 56cm ETT. The 56cm ETT seems to fit quite nicely. Now when I jump on my old bike it feels huge.

Looking at the geometry listed on BD, if I were to buy a Fantom Cross, I would choose 56cm.

Intent ? Cross Racing go down from the point you feel in the midst of (56), JRA, go Up, (58)
change the stem to suit your fit needs in either case.

You cannot test ride a bikes direct bike, but you can pay a bike shop

to make it assembled and adjusted as well as their own..


I'm Not your size..

Thanks all. Based on the suggestions I decided to go with 56 cm top tube, with the thinking that: slightly smaller top tube may work better with my slightly shorter torso.
